Hi,
some of the recently added UCM profiles are the files to be included by others, and they are not card targets. Unfortunately alsaucm doesn't know about it, and it aborts with error, e.g.
==== % alsaucm ALSA lib utils.c:67:(uc_mgr_config_load) could not open configuration file /usr/share/alsa/ucm/bytcr/bytcr.conf ALSA lib parser.c:1427:(load_master_config) error: could not parse configuration for card bytcr alsaucm: unable to obtain card list: No such file or directory ====
The similar error is found in nau8824, rt5640 and rt5651. After putting a placeholder card config file (e.g. bytcr.conf), the error is gone. But certainly we don't want to allow user to choose this as the proper card.
So, I guess we need to put some flag to each such directory indicating that it's no card config. For example, putting /usr/share/alsa/ucm/bytcr/.nocard file or such...
Not sure whether it's wise to have a file starting with dot, though. Maybe clearer to be "nocard" or any other visible one?
Comments / suggestions appreciated.
thanks,
Takashi
