permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11.

It supports multiple soundcards. If your card has +features that you can't seem to control from a mixer application, +you have come to the right place. + +.SH COMMANDS + +.SS Introduction + +The \fI\fP argument is optional. If no soundcards are specified, +setup for all cards will be saved, loaded or monitored. + +.SS store + +This command saves the current driver state for the selected soundcard +to the configuration file. + +.SS restore + +This command loads driver state for the selected soundcard from the +configuration file. If restoring fails (eventually partly), the init +action is called. + +.SS nrestore + +This command is like \fIrestore\fP, but it notifies also the daemon +to do new rescan for available soundcards. + +.SS init + +This command tries to initialize all devices to a default state. If device +is not known, error code 99 is returned. + +.SS daemon + +This command manages to save periodically the sound state. + +.SS rdaemon + +This command is like \fIdaemon\fP but restore the sound state at first. + +.SS kill + +This command notifies the daemon to do the specified operation (quit, +rescan, save_and_quit). + +.SS monitor + +This command is for monitoring the events received from the given +control device. + +.SS info + +This command shows the general information in the YAML format +collected from the given control device (sound card). + +.SS clean [filter] + +This command cleans the controls created by applications. + +The optional element identifiers are accepted as a filter. One extra +argument is parsed as an element identifiers. + +\fIExample:\fP alsactl clean 0 "name='PCM'" "name='Mic Phantom'" + +.SS dump-state + +This command dumps the current state (all cards) to stdout. + +.SS dump-cfg + +This command dumps the current configuration (all cards) to stdout. +Note that the configuration hooks are evaluated. + +.SH OPTIONS + +.TP +\fI\-h, \-\-help\fP +Help: show available flags and commands. + +.TP +\fI\-d, \-\-debug\fP +Use debug mode: a bit more verbose. + +.TP +\fI\-v, \-\-version\fP +Print alsactl version number. + +.TP +\fI\-f, \-\-file\fP +Select the configuration file to use. The default is /var/lib/alsa/asound.state. + +.TP +\fI\-a, \-\-config-dir\fP +Select the boot / hotplug ALSA configuration directory to use. The default is /var/lib/alsa. + +.TP +\fI\-l, \-\-lock\fP +Use the file locking to serialize the concurrent access to the state file (this +option is default for the global state file). + +.TP +\fI\-L, \-\-no-lock\fP +Do not use the file locking to serialize the concurrent access to the state +file (including the global state file). + +.TP +\fI\-O, \-\-lock-state-file\fP +Select the state lock file path. + +.TP +\fI\-F, \-\-force\fP +Used with restore command. Try to restore the matching control elements +as much as possible. This option is set as default now. + +.TP +\fI\-g, \-\-ignore\fP +Used with store, restore and init commands. Do not show 'No soundcards found' +and do not set an error exit code when soundcards are not installed. + +.TP +\fI\-P, \-\-pedantic\fP +Used with restore command. Don't restore mismatching control elements. +This option was the old default behavior. + +.TP +\fI\-I, \-\-no\-init\-fallback\fP +Don't initialize cards if restore fails. Since version 1.0.18, +\fBalsactl\fP tries to initialize the card with the restore operation +as default. But this can cause incompatibility with the older version. +The caller may expect that the state won't be touched if no state file +exists. This option takes the restore behavior back to the older +version by suppressing the initialization. + +.TP +\fI\-r, \-\-runstate\fP +Save restore and init state to this file. The file will contain only errors. +Errors are appended with the soundcard id to the end of file. + +.TP +\fI\-R, \-\-remove\fP +Remove runstate file at first. + +.TP +\fI\-E, \-\-env\fP #=# +Set environment variable (useful for init action or you may override +ALSA_CONFIG_PATH to read different or optimized configuration - may be +useful for "boot" scripts). + +.TP +\fI\-i, \-\-initfile\fP +The configuration file for init. By default, PREFIX/share/alsa/init/00main +is used. + +.TP +\fI\-p, \-\-period\fP +The store period in seconds for the daemon command. + +.TP +\fI\-e, \-\-pid-file\fP +The pathname to store the process-id file in the HDB UUCP format (ASCII). + +.TP +\fI\-b, \-\-background\fP +Run the task in background. + +.TP +\fI\-s, \-\-syslog\fP +Use syslog for messages. + +.TP +\fI\-n, \-\-nice\fP +Set the process priority (see 'man nice') + +.TP +\fI\-c, \-\-sched-idle\fP +Set the process scheduling policy to idle (SCHED_IDLE). + +.TP +\fI\-D, \-\-ucm-defaults\fP +Execute also the 'defaults' section from the UCM configuration. The standard +behaviour is to execute only 'once' section. + +.TP +\fI\-U, \-\-no-ucm\fP +Skip the UCM init even if available. It may be useful for the test the +legacy init configuration. + +.SH FILES +\fI/var/lib/alsa/asound.state\fP (or whatever file you specify with the +\fB\-f\fP flag) is used to store current settings for your +soundcards. The settings include all the usual soundcard mixer +settings. More importantly, alsactl is +capable of controlling other card-specific features that mixer apps +usually don't know about. + +The configuration file is generated automatically by running +\fBalsactl store\fP. Editing the configuration file by hand may be +necessary for some soundcard features (e.g. enabling/disabling +automatic mic gain, digital output, joystick/game ports, some future MIDI +routing options, etc). + +.SH SEE ALSO +\fB +amixer(1), +alsamixer(1), +aplay(1), +alsactl_init(7) +\fP + +.SH BUGS +None known. + +.SH AUTHOR +\fBalsactl\fP is by Jaroslav Kysela and Abramo Bagnara +.

+ alsactl init + + + alsactl init + July 2008 + alsactl + + + + alsactl_init + 7 + + + + + alsactl init + alsa control management - initialization + + + DESCRIPTION + "alsactl init" provides soundcard specific initialization. + + + CONFIGURATION + All "alsactl init" configuration files are placed in + /usr/share/alsa/init/ directory. The top level + configuration file is /usr/share/alsa/init/00main. + The default top-level file can be also specified using -i or + --initfile parameter for the alsactl tool. + Every file consists of a set of lines of text. All empty lines or + lines beginning with '#' will be ignored. + + Rules files + The "alsactl init" rules are read from the files located + in the /usr/share/alsa/init/*. The top + level configuration file is /usr/share/alsa/init/00main. + Every line in the rules file contains at least one key value pair. + There are two kind of keys, match and assignment keys. If all match + keys are matching against its value, the rule gets applied and the + assign keys get the specified value assigned. + + A rule may consists of a list of one or more key value pairs + separated by a comma. Each key has a distinct operation, depending + on the used operator. Valid operators are: + + + + + Compare for equality. + + + + + + + Compare for non-equality. + + + + + + + Assign a value to a key. Keys that represent a list, + are reset and only this single value is assigned. + + + + + + + Add the value to a key that holds a list + of entries. + + + + + + + Assign a value to a key finally; disallow any + later changes, which may be used to prevent changes by + any later rules. + + + + + The following key names can be used to match against device + properties: + + + + + Match the card index of the ALSA driver. + + + + + + + Set or test universal control attribute. Possible + attributes: + + + + + Numeric control identification. + + + + , + + Control interface name (CARD, HWEDEP, MIXER, PCM, RAWMIDI, TIMER, SEQUENCER) + + + + , + + Subdevice number. + + + + + + Control name + + + + + + Control index + + + + + + Control type (BOOLEAN, INTEGER, INTEGER64, ENUMERATED, BYTES, IEC958) + + + + , + + Attributes (stored in a string - use match characters * and ?): + + + + + control is readable + + + + + + control is writable + + + + + + control is volatile + + + + + + control is inactive + + + + + + control is locked + + + + + + control is TLV readable + + + + + + control is TLV writable + + + + + + control is TLV commandable + + + + + + process is owner of this control + + + + + + control created in user space + + + + + + + + + Control owner process PID number + + + + + + Control count of values + + + + + + Value range - minimum value + + + + + + Value range - maximum value + + + + + + Value range - step value + + + + + + Value range - minimum dB value + + + + + + Value range - maximum dB value + + + + + + Enumerated value - number of text items + + + + + + Enumerated value - list of text names stored between '|' character + + + + + + Value of control stored to a string delimited by + comma (,). + + + + + + Search for a control. Value "1" is returned + if a control was found. The CTL{name} key might + contain match characters * and ?. An control index + might be specified as first argument starting from + zero (e.g. CTL{do_search 2}="1"). + + + + + + Search for a controls and return total count + of matched ones. The CTL{name} key might contain match + characters * and ?. + + + + + + + + + + The relative path to sysfs subsystem specifying + the root directory of a soundcard device. Usually, + it should be set to "/class/sound/card$cardinfo{card}/device". + + + + + + + + Match sysfs attribute values of the soundcard device. + The relative path to sysfs tree must be defined by + CONFIG{sysfs_device} key. Trailing whitespace in the attribute + values is ignored, if the specified match value does + not contain trailing whitespace itself. Depending on + the type of operator, this key is also used to set + the value of a sysfs attribute. + + + + + + + + Match against the value of an environment variable. Up + to five keys can be specified per rule. + Depending on the type of operator, this key is also used + to export a variable to the environment. + + + + + + + Execute external program. The key is true, if + the program returns without exit code zero. The whole event + environment is available to the executed program. The + program's output printed to stdout is available for + the RESULT key. + Several buildin commands are available: + + + + + Search for a control. The CTL{name} key might + contain match characters * and ?. An control index + might be specified as first argument starting from + zero (e.g. PROGRAM="__ctl_search 2"). + + + + + + Search for a controls and return total count + of matched ones. The CTL{name} key might contain match + characters * and ?. + + + + + + + + + + Match the returned string of the last PROGRAM call. + This key can be used in the same or in any later rule + after a PROGRAM call. + + + + + + Most of the fields support a shell style pattern matching. + The following pattern characters are supported: + + + + + Matches zero, or any number of characters. + + + + + + Matches any single character. + + + + + + Matches any single character specified within + the brackets. For example, the pattern string 'tty[SR]' + would match either 'ttyS' or 'ttyR'. Ranges are also + supported within this match with the '-' character. + For example, to match on the range of all digits, + the pattern [0-9] would be used. If the first character + following the '[' is a '!', any characters + not enclosed are matched. + + + + + The following keys can get values assigned: + + + , , + , , + , , + + + Select universal control element. + + + + + + Value is set (written) also to soundcard's control + device and RESULT key is set to errno code. The result of + set operation is always true (it means continue with + next key on line). + + + + + + Value is set (written) also to soundcard's control + device (all control values are set to specified value) and + RESULT key is set to errno code. The result of + set operation is always true (it means continue with + next key on line). + + + + + + Value is set (written) also to soundcard's control + device (all control values are set to specified value). + The result of set operation is true when operation + succeed (it means continue with next key on line). + + + + + + + Export a variable to the environment. Depending on the type of operator, + this key is also to match against an environment variable. + + + + + + + Set RESULT variable. Note that PROGRAM also sets + this variable, but setting this variable manually + might be useful to change code execution order (included + files). + + + + + + + Named label where a GOTO can jump to. + + + + + + + Jumps to the next LABEL with a matching name. + The goto cannot jump backward. + + + + + + + Include the specified filename or files in specified directory. + + + When a directory is specified, only the files with the + extension ".conf" are read. + Also they are read in the alphabetical order. + Thus it's highly recommended to use some number prefix + (e.g. "01-something.conf") to assure the order of execucions. + + + + + + + + Check if specified file or directory exists + + + + + + + The relative path to sysfs subsystem specifying + the root directory of a soundcard device. Usually, + it should be set to "/class/sound/card$cardinfo{card}/device". + + + + + + + + PRINT value to stdout. + + + + + + + PRINT value to stderr. + + + + + + + Exit immediately and set program exit code to value + (should be integer). If value is "return" string, + parser leaves current included file and returns to parent + configuration file. + + + + + + The , , + , + , , + , + fields support simple printf-like string substitutions. + It allows the use of the complete environment set by earlier matching + rules. For all other fields, substitutions are applied while the individual rule is + being processed.

You can +scroll left/right when all controls can't be put in a single screen. +The name of each control is shown in the bottom below the volume bars. +The currently selected item is drawn in red and/or emphasized. + +Each mixer control with volume capability shows a box and the current +volume filled in that box. The volume percentages are displayed below +the volume bar for left and right channels. For a mono control, only +one value is shown there. + +When a mixer control is turned off, \fIM\fP (mute) appears below the +volume bar. When it's turned on, \fIO\fP in green appears instead. +You can toggle the switch via \fIm\fP key. + +When a mixer control has capture capability, the capture flag appears +below the volume bar, too. When the capture is turned off, +\-\-\-\-\-\-\- is shown. \fICAPTURE\fP in red appears when the +capture switch is turned on. In addition, \fIL\fP and \fIR\fP letters +appear in left and right side to indicate that left and the right +channels are turned on. + +Some controls have the enumeration list, and don't show boxes but only +texts which indicate the currently active item. You can change the +item via up/down keys. + +.SH VIEW MODES +\fBalsamixer\fP has three view modes: playback, capture and all. +In the playback view, only the controls related with playback are shown. +Similarly, only the controls for capture (recording) are shown in the capture +view. The all view mode shows all controls. The current view mode is displayed +in the top-left position together with the mixer name, etc. + +The default view mode is the playback view. You can change it via +\fI-V\fP option. + +Each view mode can be switched via keyboard commands, too. +See the next section. + +.SH KEYBOARD COMMANDS +\fBalsamixer\fP recognizes the following keyboard commands to control the soundcard. +Commands shown here in upper case can also be given in lower case. +To be reminded of these keystrokes, hit the \fIh\fP key. + +.SS +General Controls + +The \fILeft\fP and \fIright arrow\fP keys are used to select the +channel (or device, depending on your preferred terminology). You can +also use \fIn\fP ("next") and \fIp\fP ("previous"). + +The \fIUp\fP and \fIDown Arrows\fP control the volume for the +currently selected device. You can also use \fI+\fP or \fI\-\fP for the +same purpose. Both the left and right signals are affected. For +independent left and right control, see below. + +The \fIB\fP or \fI=\fP key adjusts the balance of volumes on left and +right channels. + +\fIM\fP toggles muting for the current channel (both left and right). +If the hardware supports it, you can +mute left and right independently by using \fI,\fP (or \fI<\fP) and +\fI.\fP (or \fI>\fP) respectively. + +\fISPACE\fP enables recording for the current channel. If any other +channels have recording enabled, they will have their recording function +disabled first. This only works for valid input channels, of course. + +\fIL\fP re-draws the screen. + +.SS +View Mode Controls +Function keys are used to change view modes. +You can switch to the help mode and the proc info mode via \fIF1\fP and +\fIF2\fP keys, respectively. +On terminals that can't use function keys like gnome\-terminal, \fI?\fP and +\fI/\fP keys can be used alternatively for help and proc modes. + +\fIF3\fP, \fIF4\fP and \fIF5\fP keys are used to switch to playback, capture +and all view mode, respectively. \fITAB\fP key toggles the +current view mode circularly. + +.SS +Quick Volume Changes + +\fIPageUp\fP increases volume by 5. + +\fIPageDown\fP decreases volume by 5. + +\fIEnd\fP sets volume to 0. + +You can also control left & right levels for the current channel +independently, as follows: + +[\fIQ\fP | \fIW\fP | \fIE\fP ] -- turn UP [ left | both | right ] + +[\fIZ\fP | \fIX\fP | \fIC\fP ] -- turn DOWN [ left | both | right ] + +If the currently selected mixer channel is not a stereo channel, then +all UP keys will work like \fIW\fP, and all DOWN keys will work like \fIX\fP. + +The number keys from \fI0\fP to \fI9\fP are to change the absolute volume +quickly. They correspond to 0 to 90% volume. + +.SS +Selecting the Sound Card + +You can select another sound card by pressing the \fIF6\fP or \fIS\fP keys. +This will show a list of available sound cards to choose from, +and an entry to enter the mixer device name by hand. + +.SS +Exiting + +Quit the program with \fIALT Q\fP, or by hitting \fIESC\fP. +Please note that you might need to hit \fIESC\fP twice on some terminals +since it's regarded as a prefix key. + +.SH VOLUME MAPPING +In \fBalsamixer\fP, the volume is mapped to a value that is more natural +for a human ear. The mapping is designed so that the position in the +interval is proportional to the volume as a human ear would perceive +it, i.e. the position is the cubic root of the linear sample +multiplication factor. For controls with a small range (24 dB or +less), the mapping is linear in the dB values so that each step has +the same size visually. + +Only for controls without dB information, a linear mapping of the +hardware volume register values is used (this is the same algorithm as +used in the old \fBalsamixer\fP). + +.SH FILES + +Configuration is read from the following files: + +\fI$XDG_CONFIG_HOME\fP/alsamixer.rc + +\fI$HOME\fP/.config/alsamixer.rc + +.SH CONFIGURATION + +Comments start with '#'. + +.TP +\fBcolor\fP \fIelement\fP \fIforeground\fP \fIbackground\fP [\fIattribute...\fP] + +Valid values for \fIforeground\fP and \fIbackground\fP are: red, green, yellow, blue, magenta, cyan, white, black, none / default. + +Valid values for \fIattribute\fP are: bold, normal, reverse, underline, dim, italic, blink. + +See section \fBTHEME ELEMENTS\fP for a list of \fIelements\fP. + +.TP +\fBset\fP \fIoption\fP \fIvalue\fP + +\fBmouse_wheel_step\fP \fI\fP + +Set the mouse wheel step to \fI\fP + +\fBmouse_wheel_focuses_control\fP \fI0|1\fP + +If enabled (\fI1\fP), mixer controls can be changed by hovering over them and scrolling the mouse wheel. + +\fBbackground\fP \fIcolor\fP + +Set the default background color + +.TP +\fBbind\fP \fIkey_definition\fP \fIcommand\fP + +A \fIkey_definition\fP may be: + - a single character + - a combination with control: C-a + - a combination with alt: M-a + - a special keyname: Enter, Escape, PageUp, PageDown, Left, Down, Right, Up, Home, End, Backspace, F1 ..

An audio use case can be defined by a **verb** and **device** parameter. + +The verb describes the use case action i.e. a phone call, listening to music, +recording a conversation etc. The device describes the physical audio capture +and playback hardware i.e. headphones, phone handset, bluetooth headset, etc. + + +OPTIONS +======= + +Available options: + + **-h**, **--help** + this help + + **-c**, **--card** `NAME` + open card NAME + + **-i**, **--interactive** + interactive mode + + **-b**, **--batch** `FILE` + batch mode (use ``'-'`` for the stdin input) + + **-n**, **--no-open** + do not open first card found + + +Available commands: + + ``open`` `NAME` + open card NAME. + + valid names are sound card names as listed in ``/usr/share/alsa/ucm``. + + ``reset`` + reset sound card to default state. + + ``reload`` + reload configuration. + + ``listcards`` + list available cards. + + ``list`` `IDENTIFIER` + list command, for items returning two entries (value+comment). + + the value of the `IDENTIFIER` argument can be: + + - ``_verbs`` - get verb list (in pair verb+comment) + - ``_devices[/{verb}]`` - get list of supported devices (in pair device+comment) + - ``_modifiers[/{verb}]`` - get list of supported modifiers (in pair modifier+comment) + + The forms without the trailing ``/{verb}`` are valid only after a specific + verb has been set. + + ``list1`` `IDENTIFIER` + list command, for lists returning one item per entry. + + the value of the `IDENTIFIER` argument can vary depending on the context, + it can be: + + - ``TQ[/{verb}]`` - get list of Tone Quality identifiers + - ``_enadevs`` - get list of enabled devices + - ``_enamods`` - get list of enabled modifiers + - ``_supporteddevs/{modifier}|{device}[/{verb}]`` - list of supported devices + - ``_conflictingdevs/{modifier}|{device}[/{verb}]`` - list of conflicting devices + + ``get`` `IDENTIFIER` + get string value. + + the value of the `IDENTIFIER` argument can be: + + - ``_verb`` - return current verb + - ``[=]{NAME}[/[{modifier}|{/device}][/{verb}]]`` (For valid NAMEs look at the + ALSA `Use Case Interface`_) + + + ``geti`` `IDENTIFIER` + get integer value. + + the value of the `IDENTIFIER` argument can be: + + - ``_devstatus/{device}`` + - ``_modstatus/{device}`` + + ``set`` `IDENTIFIER` `VALUE` + set string value + + The value of the `IDENTIFIER` argument can be: + + - ``_verb`` - set the verb to `VALUE` + - ``_enadev`` - enable the device specified by `VALUE` + - ``_disdev`` - disable the device specified by `VALUE` + - ``_swdev/{old_device}`` - switche device: + + - disable `old_device` and then enable the device specified by + `VALUE` + - if no device was enabled just return + + - ``_enamod`` - enable the modifier specified by `VALUE` + - ``_dismod`` - disable the modifier specified by `VALUE` + - ``_swmod/{old_modifier}`` - switch modifier: + + - disable `old_modifier` and then enable the modifier specified by + `VALUE` + - if no modifier was enabled just return + + Note that the identifiers referring to devices and modifiers are valid + only after setting a verb. + + ``h``, ``help`` + help + + ``q``, ``quit`` + quit + + +FILES +===== + +The master use case files for each supported sound card are in ``/usr/share/alsa/ucm``. + +For example, the master use case file for the `Pandaboard` card is in +``/usr/share/alsa/ucm/PandaBoard/PandaBoard.conf``, this file lists all the +supported use cases, e.g. + +:: + + SectionUseCase."HiFi" { + File "hifi" + Comment "Play HiFi quality Music." + } + ... + + +Each use case defines a _verb, which is described in the file specified in +the ``File`` directive, like above. + +The ``HiFi`` verb above is described in +``/usr/share/alsa/ucm/PandaBoard/hifi``. + +For more details on the syntax of UCM files, see the alsa-lib source code: +http://git.alsa-project.org/?p=alsa-lib.git;a=blob;f=src/ucm/parser.c + + +EXAMPLES OF USE +=============== + +Some commands, like for instance ``list _devices``, +can only work after setting a ``_verb`` in the **same execution**, for +instance this sequence doesn't work: + +:: + + # alsaucm -c bytcr-rt5640 set _verb HiFi + # alsaucm -c bytcr-rt5640 list _devices + + +However this command does: + +:: + + # alsaucm -n -b - < + */ + +#include +#include +#include +#include +#include "usecase.h" +#include "aconfig.h" +#include "version.h" + +struct renderer { + int (*init)(struct renderer *r);

In this mode, libffado +adds unit directory into configuration ROM of 1394 OHCI controller where Linux +system runs. The unit directory can be found by the other node on the same bus. +Linux system running on the node can transfer isochronous packet with audio +data frame to the unit.

In this mode, in\-kernel drivers should operate hardware to +generate periodical notification for transmission of audio data frame. The +interval of notification is equivalent to the same amount of audio data frame +as one period of buffer, against actual time. + +In a handler assigned to the notification, a helper function of ALSA PCM core +is called to update a position to head of hardware transmission, then compare +it with a position to head of application operation to judge overrun/underrun +(XRUN) and to wake up blocked processes. + +For this purpose, hardware IRQ of controller for serial audio bus such as +Inter\-IC sound is typically used. In this case, the controller generates the +IRQ according to transmission on the serial audio bus. In the handler assigned +to the IRQ, direct media access (DMA) transmission is requested between +dedicated host memory and device memory. + +If target hardware doesn't support this kind of mechanism, the periodical +notification should be emulated by any timer; e.g. hrtimer, kernel timer. +External PCM plugins generated by PCM plugin SDK in alsa\-lib should also +emulate the above behaviour. + +In this mode, PCM applications are programmed according to typical way of I/O +operations. They execute blocking system calls to read/write audio data frame +in buffer of PCM substream, or blocking system calls to wait until any audio +data frame is available. In +.I axfer +, this is called +.I IRQ\-based +scheduling model and a default behaviour. Users can explicitly configure this +mode by usage of +.I \-\-sched\-model +option with +.I irq +value. + +.SS Timer\-based scheduling model + +The +.I no\-period\-wakeup +mode is an optional mode of runtime of PCM substream. The mode assumes a +specific feature of hardware and assist of in\-kernel driver and PCM +applications. In this mode, in\-kernel drivers don't operate hardware to +generate periodical notification for transmission of audio data frame. +The hardware should automatically continue transmission of audio data frame +without periodical operation of the drivers; e.g. according to auto\-triggered +DMA transmission, a chain of registered descriptors. + +In this mode, nothing wakes up blocked processes, therefore PCM applications +should be programmed without any blocking operation. For this reason, this mode +is enabled when the PCM applications explicitly configure hardware parameter to +runtime of PCM substream, to prevent disorder of existing applications. +Additionally, nothing maintains timing for transmission of audio data frame, +therefore the PCM applications should voluntarily handle any timer to queue +audio data frame in buffer of the PCM substream for lapse of time. Furthermore, +instead of driver, the PCM application should call a helper function of ALSA +PCM core to update a position to head of hardware transmission and to check +XRUN. + +In +.I axfer +, this is called +.I timer\-based +scheduling model and available as long as hardware/driver assists +.I no\-period\-wakeup +runtime. Users should explicitly set this mode by usage of +.I \-\-sched\-model +option with +.I timer +value. + +In the scheduling model, PCM applications need to care of available space on +PCM buffer by lapse of time, typically by yielding CPU and wait for +rescheduling. For the yielding, timeout is calculated for preferable amount of +PCM frames to process. This is convenient to a kind of applications, like sound +servers. when an I/O thread of the server wait for the timeout, the other +threads can process audio data frames for server clients. Furthermore, with +usage of rewinding/forwarding, applications can achieve low latency between +transmission position and handling position even if they uses large size of +PCM buffers. + +.SS Advantages and issues + +Ideally, timer\-based scheduling model has some advantages than IRQ\-based +scheduling model. At first, no interrupt context runs for PCM substream. The +PCM substream is handled in any process context only. No need to care of race +conditions between IRQ and process contexts. This reduces some concerns for +some developers of drivers and applications. Secondary, CPU time is not used +for handlers on the interrupt context. The CPU time can be dedicated for the +other tasks. This is good in a point of Time Sharing System. Thirdly, hardware +is not configured to generate interrupts. This is good in a point of reduction +of overall power consumption possibly. + +In either scheduling model, the hardware should allow drivers to read the +number of audio data frame transferred between the dedicated memory and the +device memory for audio serial bus. However, in timer\-based scheduling model, +fine granularity and accuracy of the value is important. Actually hardware +performs transmission between dedicated memory and device memory for a small +batch of audio data frames or bytes. In a view of PCM applications, the +granularity in current transmission is required to decide correct timeout for +each I/O operation. As of Linux kernel v4.21, ALSA PCM interface between +kernel/userspace has no feature to report it. + +.SH COMPATIBILITY TO APLAY + +The +.B transfer +subcommand of +.B axfer +is designed to keep compatibility to aplay(1). However some options below are +not compatible due to several technical reasons. + +.TP +.I \-I, \-\-separate\-channels +This option is supported just for files to store audio data frames corresponding +to each channel. In aplay(1) implementation, this option has an additional +effect to use PCM buffer aligned to non\-interleaved order if a target device +supports. As of 2018, PCM buffer of non\-interleaved order is hardly used by +sound devices. + +.TP +.I \-A, \-\-avail\-min=# +This option indicates threshold to wake up blocked process in a unit of +audio data frame. Against aplay(1) implementation, this option has no effect +with +.I \-\-mmap +option as well as +.I timer +of +.I \-\-sched\-model +option. + +.TP +.I \-R, \-\-start\-delay=# +This option indicates threshold to start prepared PCM substream in a unit of +audio data frame. Against aplay(1) implementation, this option has no effect +with +.I \-\-mmap +option as well as +.I timer +of +.I \-\-sched\-model +option. + +.TP +.I \-T, \-\-stop\-delay=# +This option indicates threshold to stop running PCM substream in a unit of +audio data frame. Against aplay(1) implementation, this option has no effect +with +.I \-\-mmap +option as well as +.I timer +of +.I \-\-sched\-model +option. + +.TP +.I \-\-max\-file\-time=# +This option is unsupported. In aplay(1) implementation, the option has an +effect for capture transmission to save files up to the same number of data +frames as the given value by second unit, or the maximum number of data frames +supported by used file format. When reaching to the limitation, used file is +closed, then new file is opened and audio data frames are written. However, this +option requires extra handling of files and shall increase complexity of main +loop of axfer. + +.TP +.I \-\-use\-strftime=FORMAT +This option is unsupported. In aplay(1) implementation, the option has an effect +for capture transmission to generate file paths according to given format in +which some extra formats are available as well as formats supported by +strftime(3). However, this option requires extra string processing for file +paths and it\(aqs bothersome if written in C language. + +.TP +.I \-\-process\-id\-file=FILEPATH +This option is unsupported. In aplay(1) implementation, the option has an effect +to create a file for given value and write out process ID to it. This file +allows users to get process ID and send any POSIX signal to aplay process. +However, this idea has some troubles for file locking when multiple aplay +processes run with the same file. + +.TP +.I \-V, \-\-vumeter=TYPE +This option is not supported at present. In aplay(1) implementation, this option +has an effect to occupy stdout with some terminal control characters and display +vumeter for monaural and stereo channels. However, some problems lay; this +feature is just for audio data frames with PCM format, this feature brings +disorder of terminal after aborting, stdout is not available for pipeline. + +.TP +.I \-i, \-\-interactive +This option is not supported at present. In aplay(1) implementation, this option +has an effect to occupy stdin for key input and suspend/resume PCM substream +according to pushed enter key. However, this feature requires an additional +input handling in main loop and leave bothersome operation to maintain PCM +substream. + +.TP +.I \-m, \-\-chmap=CH1,CH2,... +ALSA PCM core and control core doesn't support this feature, therefore +remapping should be done in userspace. This brings overhead to align audio +data frames, especially for mmap operation. Furthermore, as of alsa-lib v1.1.8, +some plugins don't support this feature expectedly, thus this option is a lack +of transparent operation. At present, this option is not supported yet not to +confuse users. + +.TP +.I SIGTSTP, SIGCONT +This performs suspend/resume of PCM substream. In aplay(1) implementation, +these operations bring XRUN state to the substream, and suspend/resume is done +in interactive mode in the above. Some developers use the signal for recovery +test from XRUN. At present, no alternative is supported for the test. + +.TP +.I SIGUSR1 +This is not supported. In aplay(1) implementation, this signal is assigned to a +handler to close a current file to store audio data frame and open a new file +to continue processing. However, as well as +.I \-\-max\-file\-time +option, this option should increase complexity of main loop of axfer. + +.SH DESIGN + +.SS Modular structure + +This program consists of three modules; +.I xfer +, +.I mapper +and +.I container +\&. +Each module has an abstraction layer to enable actual implementation. + +.nf + -------- ---------- ------------- +device <-> | xfer | <-> | mapper | <-> | container | <-> file + -------- ---------- ------------- + libasound single wav + libffado multiple au + voc + raw +.fi + +The +.I xfer +module performs actual transmission to devices and nodes. The module can have +several transmission backends. As a default backend, +.I libasound +backend is used to perform transmission via alsa\-lib APIs. The module allows +each backend to parse own command line options. + +The +.I container +module performs to read/write audio data frame via descriptor for file/stream +of multimedia container or raw data. The module automatically detect type of +multimedia container and parse parameters in its metadata of data header. At +present, three types of multimedia containers are supported; Microsoft/IBM +RIFF/Wave ( +.I wav +), Sparc AU ( +.I au +) and Creative Technology voice ( +.I voc +). Additionally, a special container is prepared for raw audio data ( +.I raw +). + +The +.I mapper +module handles buffer layout and alignment for transmission of audio data frame. +The module has two implementations; +.I single +and +.I multiple +\&. +The +.I single +backend uses one container to construct the buffer. The +.I multiple +backend uses several containers to construct it. + +.SS Care of copying audio data frame + +Between the +.I xfer +module and +.I mapper +module, a pointer to buffer including audio data frames is passed. This buffer +has two shapes for interleaved and non\-interleaved order. For the former, the +pointer points to one buffer. For the latter, the pointer points to an array in +which each element points to one buffer. Between the +.I mapper +module and +.I container +module, a pointer to one buffer is passed because supported media containers +including raw type store audio data frames in interleaved order. + +In passing audio data frame between the modules, axfer is programmed to avoid +copying between a buffer to another buffer as much as possible. For example, in +some scenarios below, no copying occurs between modules. + + - xfer(mmap/interleaved), mapper(single), container(any) + - xfer(mmap/non\-interleaved), mapper(multiple), containers(any) + +.SS Unit test + +For each of the +.I mapper +and +.I container +module, unit test is available. To run the tests, execute below command: + +.nf +$ make test +.fi + +Each test iterates writing to file and reading to the file for many times and it +takes long time to finish.

ALSABAT can be used to test audio quality, stress test +features and test audio before and after PM state changes. + +ALSABAT's design is relatively simple. ALSABAT plays an audio stream and +captures the same stream in either a digital or analog loop back. It then +compares the captured stream using a FFT to the original to determine if +the test case passes or fails. + +ALSABAT can either run wholly on the target machine being tested (standalone +mode) or can run as a client/server mode where by alsabat client runs on the +target and runs as a server on a separate tester machine. The client/server +mode still requires some manual interaction for synchronization, but this +is actively being developed for future releases. + +The hardware testing configuration may require the use of an analog cable +connecting target to tester machines or a cable to create an analog +loopback if no loopback mode is available on the sound hardware that is +being tested. +An analog loopback cable can be used to connect the "line in" to "line out" +jacks to create a loopback. If only headphone and mic jacks (or combo jack) +are available then the following simple circuit can be used to create an +analog loopback :- + +https://source.android.com/devices/audio/loopback.html + +If tinyalsa is installed in system, user can choose tinyalsa as backend lib +of alsabat, with configure option "--enable-alsabat-backend-tiny". + +.SH OPTIONS +.TP +\fI\-h, \-\-help\fP +Help: show syntax. +.TP +\fI\-D\fP +Select sound card to be tested by name. +.TP +\fI\-P\fP +Select the playback PCM device. +.TP +\fI\-C\fP +Select the capture PCM device. +.TP +\fI\-f\fP +Sample format +.br +Recognized sample formats are: U8 S16_LE S24_3LE S32_LE +.br +Some of these may not be available on selected hardware +.br +The available format shortcuts are: +.nf +\-f cd (16 bit little endian, 44100, stereo) [\-f S16_LE \-c2 \-r44100] +\-f dat (16 bit little endian, 48000, stereo) [\-f S16_LE \-c2 \-r48000] +.fi +If no format is given S16_LE is used. +.TP +\fI\-c\fP +The number of channels. The default is one channel. +Valid values at the moment are 1 or 2. +.TP +\fI\-r\fP +Sampling rate in Hertz. The default rate is 44100 Hertz. +Valid values depends on hardware support. +.TP +\fI\-n\fP +Duration of generated signal. +The value could be either of the two forms: +.br +1. Decimal integer, means number of frames; +.br +2. Floating point with suffix 's', means number of seconds. +.br +The default is 2 seconds. +.TP +\fI\-k\fP +Sigma k value for analysis. +.br +The analysis function reads data from WAV file, run FFT against the data +to get magnitude of frequency vectors, and then calculates the average +value and standard deviation of frequency vectors. After that, we define +a threshold: +.br +threshold = k * standard_deviation + mean_value +.br +Frequencies with amplitude larger than threshold will be recognized as a +peak, and the frequency with largest peak value will be recognized as a +detected frequency. +.br +ALSABAT then compares the detected frequency to target frequency, to +decide if the detecting passes or fails. +.br +The default value is 3.0. +.TP +\fI\-F\fP +Target frequency for signal generation and analysis, in Hertz. +The default is 997.0 Hertz. +Valid range is (DC_THRESHOLD, 40% * Sampling rate). +.TP +\fI\-p\fP +Total number of periods to play or capture. +.TP +\fI\-\-log=#\fP +Write stderr and stdout output to this log file. +.TP +\fI\-\-file=#\fP +Input WAV file for playback. +.TP +\fI\-\-saveplay=#\fP +Target WAV file to save capture test content. +.TP +\fI\-\-local\fP +Internal loopback mode. +Playback, capture and analysis internal to ALSABAT only. This is intended +for developers to test new ALSABAT features as no audio is routed outside +of ALSABAT. +.TP +\fI\-\-standalone\fP +Add support for standalone mode where ALSABAT will run on a different machine +to the one being tested. +In standalone mode, the sound data can be generated, playback and captured +just like in normal mode, but will not be analyzed. +The ALSABAT being built without libfftw3 support is always in standalone mode. +The ALSABAT in normal mode can also bypass data analysis using option +"--standalone". +.TP +\fI\-\-roundtriplatency\fP +Round trip latency test. +Audio latency is the time delay as an audio signal passes through a system. +There are many kinds of audio latency metrics. One useful metric is the +round trip latency, which is the sum of output latency and input latency. +.TP +\fI\-\-snr\-db=#\fP +Noise detection threshold in SNR (dB). 26dB indicates 5% noise in amplitude. +ALSABAT will return error if signal SNR is smaller than the threshold. +.TP +\fI\-\-snr\-pc=#\fP +Noise detection threshold in percentage of noise amplitude (%). +ALSABAT will return error if the noise amplitude is larger than the threshold. + +.SH EXAMPLES + +.TP +\fBalsabat \-P plughw:0,0 \-C plughw:0,0 \-c 2 \-f S32_LE \-F 250\fR +Generate and play a sine wave of 250 Hertz with 2 channel and S32_LE format, +and then capture and analyze. + +.TP +\fBalsabat \-P plughw:0,0 \-C plughw:0,0 \-\-file 500Hz.wav\fR +Play the RIFF WAV file "500Hz.wav" which contains 500 Hertz waveform LPCM +data, and then capture and analyze. + +.SH RETURN VALUE +.br +On success, returns 0. +.br +If no peak be detected, returns -1001; +.br +If only DC be detected, returns -1002; +.br +If peak frequency does not match with the target frequency, returns -1003. + +.SH SEE ALSO +\fB +aplay(1) +\fP + +.SH BUGS +Currently only support RIFF WAV format with PCM data.

The time signature is 4:4 by default. + +.SH AUTHOR +Clemens Ladisch diff --git a/seq/aplaymidi/arecordmidi.c b/seq/aplaymidi/arecordmidi.c new file mode 100644 index 0000000..a4c1181 --- /dev/null +++ b/seq/aplaymidi/arecordmidi.c @@ -0,0 +1,921 @@ +/* + * arecordmidi.c - record standard MIDI files from sequencer ports + * + * Copyright (c) 2004-2005 Clemens Ladisch + * + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It implies \fI\-s\fP option, too. + +.SH OPTIONS + +.TP +.I \-h,\-\-help +Prints a list of options. + +.TP +.I \-V,\-\-version +Prints the current version. + +.TP +.I \-p,\-\-port=client:port,... +Sets the sequencer port(s) from which events are recorded. + +A client can be specified by its number, its name, or a prefix of its +name. A port is specified by its number; for port 0 of a client, the +":0" part of the port specification can be omitted. + +\fBarecordmidi2\fP creates a UMP Endpoint containing the same number +of Function Blocks as specified by this option, each of which is +connected to the specified port as a source. + +When no source ports are specified with \fI\-p\fP option, +\fBarecordmidi2\fP creates a UMP Endpoint with full 16 Function Blocks +and records from those inputs. User can connect the sequencer ports +freely via \fBaconnect\fP, for example. This mode can be used +together with the interactive mode via \fI\-r\fP option. + +.TP +.I \-b,\-\-bpm=beats +Sets the musical tempo of the MIDI file, in beats per minute. +The default value is 120 BPM. + +.TP +.I \-t,\-\-ticks=ticks +Sets the resolution of timestamps (ticks) in the MIDI file, +in ticks per beat. +The default value is 384 ticks/beat. + +.TP +.I \-i,\-\-timesig=numerator:denominator +Sets the time signature for the MIDI file. + +The time signature is specified as usual with two numbers, representing +the numerator and denominator of the time signature as it would be +notated. The denominator must be a power of two. Both numbers should be +separated by a colon. The time signature is 4:4 by default. + +.TP +.I \-n,\-\-num-events=events +Stops the recording after receiving the given number of events. + +.TP +.I \-u,\-\-ump=version +Sets the UMP MIDI protocol version. Either 1 or 2 has to be given for +MIDI 1.0 and MIDI 2.0 protocol, respectively. +Default is 1. + +.TP +.I \-r,\-\-interactive +Run in the interactive mode. \fBarecordmidi2\fP waits for a RETURN +key input from the terminal to start the recording. After starting, +the recording ends when another RETURN key is input from the +terminal. The received events before the start of recording are +discarded. + +.TP +.I \-s,\-\-silent +Don't print messages to stdout. + +.TP +.I \-P,\-\-profile=file +Read the UMP data from the given file and put them into the +configuration section of the recorded output. +The file must contain only valid UMP data encoded in big-endian. + +.TP +.I \-\-song=text, \-\-clip=text, \-\-copyright=text, \-\-composer=text, \ +\-\-lyricist=text, \-\-arranger=text, \-\-publisher=text, \ +\-\-performer=text \-\-accompany=text, \-\-date=text, \-\-location=text +Put the given meta data text in the configuration section. + +.SH SEE ALSO +arecordmidi(1) +.br +aplaymidi2(1) + +.SH AUTHOR +Takashi Iwai + + diff --git a/seq/aplaymidi2/arecordmidi2.c b/seq/aplaymidi2/arecordmidi2.c new file mode 100644 index 0000000..467af65 --- /dev/null +++ b/seq/aplaymidi2/arecordmidi2.c @@ -0,0 +1,717 @@ +/* + */ + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include "aconfig.h" +#include "version.h" + +static snd_seq_t *seq;

If you +want to test another sound device you will have first to get a list of +all of the sound cards in your system and the devices associated with +those cards. Notice that there might be for example, one device for +analog sound, one for digital sound and one for HDMI sound. +To get the list of available cards and devices you can run \fBaplay \-L\fR. + +.P \fBaplay\fR's output will be similar to this one: + +.nf +$ aplay \-L +null + Discard all samples (playback) or generate zero samples (capture) +default:CARD=ICH5 + Intel ICH5, Intel ICH5 + Default Audio Device +front:CARD=ICH5,DEV=0 + Intel ICH5, Intel ICH5 + Front speakers +surround40:CARD=ICH5,DEV=0 + Intel ICH5, Intel ICH5 + 4.0 Surround output to Front and Rear speakers +(...) +.fi + +.P Each of the devices is listed in the beginning of the definition so, +in the above example, there are four devices listed: null, default, front +and surround40. So, if you want to test the last device you can +run \fBspeaker\-test \-Dsurround40:ICH5 \-c 6\fR. The \fB\-c\fR option will +indicate that the six audio channels in the device have to be tested. + + + + + +.SH OPTIONS + +.TP +\fB\-c\fP | \fB\-\-channels\fP \fINUM\fP +\fINUM\fP channels in stream + +.TP +\fB\-D\fP | \fB\-\-device\fP \fINAME\fP +PCM device name \fINAME\fP + +.TP +\fB\-f\fP | \fB\-\-frequency\fP \fIFREQ\fP +sine wave of \fIFREQ\fP Hz + +.TP +\fB\-\-help\fP +Print usage help + +.TP +\fB\-b\fP | \fB\-\-buffer\fP \fITIME\fP +Use buffer size of \fITIME\fP microseconds. +When 0 is given, use the maximal buffer size. +The default value is 0. + +.TP +\fB\-p\fP | \fB\-\-period\fP \fITIME\fP +Use period size of \fITIME\fP microseconds. +When 0 is given, the periods given by \fB\-P\fP option is used. +The default value is 0. + +.TP +\fB\-P\fP | \fB\-\-nperiods\fP \fIPERIODS\fP +Use number of periods.

If you can hear any tone it may indicate resonances in your speaker system or room. + +\fB\-t st2095\fP means use bandlimited pink noise at -18.5dB AES FS, generated according to SMPTE ST-2095:1-2015. +In addition to speaker localization it may be used for system calibration, for example 85dB for thater drivers, with an extra +10dB for subwoofers. +Per the spec, it is intended "to be used in calibrating the sound pressure level and +electroacoustic response of a cinema B-chain system." +Note that sampling rates less than 48KHz are outside the scope of the spec, and an attempt will be made to construct a reduced rate filter. + +\fB\-t sine\fP means to use sine wave. + +\fB\-t wav\fP means to play WAV files, either pre-defined files or given via \fB\-w\fP option. + +You can pass the number from 1 to 3 as a backward compatibility. + +.TP +\fB\-l\fP | \fB\-\-nloops\fP \fICOUNT\fP + +Specifies the number of loops. Zero means to run infinitely. + +When \fB\-s\fP option below with a valid channel is given, \fBspeaker\-test\fP will perform +always a single-shot without looping. + +.TP +\fB\-s\fP | \fB\-\-speaker\fP \fICHANNEL\fP +Do a single-shot speaker test for the given channel. The channel number starts from 1. +The channel number corresponds to left, right, rear-left, rear-right, center, LFE, +side-left, side-right, and so on. + +For example, when 1 is passed, it tests the left channel only once rather than both channels +with looping. + +.TP +\fB\-w\fP | \fB\-\-wavfile\fP \fIFILE\fP +Use the given WAV file for the playback instead of pre-defined WAV files. + +.TP +\fB\-W\fP | \fB\-\-wavdir\fP \fIDIRECTORY\fP +Specify the directory containing WAV files for playback. +The default path is \fI/usr/share/sounds/alsa\fP. + +.TP +\fB\-m\fP | \fB\-\-chmap\fP \fIMAP\fP +Pass the channel map to override. +If the playback in a specific channel order or channel positions is +required, pass the channel position strings to this option. + +.TP +\fB\-X\fP | \fB\-\-force-frequency\fP +Allow supplied \fIFREQ\fP to be outside the default range of 30-8000Hz.

The driver is also +tightly coupled to the DSP firmware version meaning extra care +is needed to keep the driver and firmware version in sync. +New firmware features also mean driver updates. + +The ALSA topology project removes the need for re-writing or +porting audio drivers to different devices or different firmwares: +Drivers have no hard coded topology data meaning a single driver +can be used on different devices by updating the topology data +from the file system. Firmware updates can be pushed without +having to update the drivers. The new firmware just needs +to include an updated topology file describing the update. + +OPTIONS +======= + +Available options: + + **-h**, **--help** + this help + + **-V**, **--version** + show the utility version and versions of used libraries + + **-c**, **--compile** `FILE` + source configuration file for the compilation + + **-d**, **--decode** `FILE` + source binary topology file for the decode + + **-n**, **--normalize** `FILE` + parse and save the configuration file in the normalized format + + **-u**, **--dump** `FILE` + parse and save the configuration file in the specified format + + **-o**, **--output** `FILE` + output file + + **-v**, **--verbose** `LEVEL` + set verbose level + + **-s**, **--sort** + sort the configuration identifiers (set for normalization) + + **-x**, **--nocheck** + save the configuration without additional integrity check + + **-z**, **--dapm-nosort** + do not sort DAPM graph items (like in version 1.2.1-) + + +FILES +===== + +The master topology files for each supported sound card are in +``/usr/share/alsa/topology``. + +For example, the master use case file for the `broadwell` card is in +``/usr/share/alsa/topology/broadwell/broadwell.conf``, this file +describes the audio hardware for the driver. + +For more details on the syntax of UCM files, see the alsa-lib source code: +http://git.alsa-project.org/?p=alsa-lib.git;a=blob;f=src/topology/parser.c + +SEE ALSO +======== + +* Topology Interface: http://www.alsa-project.org/alsa-doc/alsa-lib/group__topology.html + +BUGS +==== + +None known. diff --git a/topology/nhlt/Makefile.am b/topology/nhlt/Makefile.am new file mode 100644 index 0000000..1b68382 --- /dev/null +++ b/topology/nhlt/Makefile.am @@ -0,0 +1,29 @@ +alsatplg_module_nhlt_LTLIBRARIES = libalsatplg_module_nhlt.la + +alsatplg_module_nhltdir = @ALSA_TOPOLOGY_PLUGIN_DIR@ + +AM_CFLAGS = -Wall -fvisibility=hidden -I$(top_srcdir)/include -I$(top_srcdir)/topology +AM_LDFLAGS = -module -avoid-version -export-dynamic -no-undefined $(LDFLAGS_NOUNDEFINED) + +libalsatplg_module_nhlt_la_SOURCES = nhlt-processor.c \ + intel/intel-nhlt.c \ + intel/dmic-nhlt.c \ + intel/dmic/dmic-debug.c intel/dmic/dmic-process.c \ + intel/ssp-nhlt.c \ + intel/ssp/ssp-debug.c intel/ssp/ssp-process.c + +noinst_HEADERS = nhlt.h \ + intel/intel-nhlt.h \ + intel/dmic-nhlt.h \ + intel/dmic/dmic-intel.h \ + intel/dmic/dmic-process.h \ + intel/dmic/dmic-debug.h \ + intel/dmic/dmic-internal.h \ + intel/dmic/pdm-decim-fir.h \ + intel/ssp-nhlt.h \ + intel/ssp/ssp-debug.h \ + intel/ssp/ssp-intel.h \ + intel/ssp/ssp-process.h \ + intel/ssp/ssp-internal.h + +libalsatplg_module_nhlt_la_LIBADD = @ALSA_LIBS@ diff --git a/topology/nhlt/intel/dmic-nhlt.c b/topology/nhlt/intel/dmic-nhlt.c new file mode 100644 index 0000000..7c98a3b --- /dev/null +++ b/topology/nhlt/intel/dmic-nhlt.c @@ -0,0 +1,519 @@ +// SPDX-License-Identifier: BSD-3-Clause +// +// Copyright(c) 2021 Intel Corporation.
