This patch adds --ucm-nodev (or -X) option to get those
messages back. The code works only with library 1.2.6+.
By default, these messages are suppressed:
alsactl[xxx]: alsa-lib parser.c:242:(error_node) UCM is not supported for this HDA model (HDA Intel PCH...)
alsactl[xxx]: alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -6
