Was the corresponding change for alsa-ucm-conf submitted to upstream?

IMO, the profile name sounds too generic.  It's better to have with
some model name at least so that it can be identified more uniquely.


thanks,

It's no longer necessary to force the card names in the drivers. UCM can match 
the USB vendor / device IDs from the 'components' string, too.

I think that we should abandon this way of the UCM configuration selection for 
new devices with device IDs. The kernel already exports necessary information 
to select the right UCM configuration in the user space.

I had tested with USB-Audio.conf that the system seems not to apply the UCM config.

The related info of the test machine shows below.

Looks like the alsa-lib in the ubuntu 20.04 doesn't support it.

I cannot comment specific distribution packages. It seems that alsa-lib-1.2.2 
in Ubuntu has many later UCM upstream changes, but I cannot verify, if it's 
enough for this file. I would recommend to use upstream alsa-lib and 
alsa-ucm-conf 1.2.5 or later (from the repository) for tests.

Also, please, create an issue or pull request on github for this problem:

   https://github.com/alsa-project/alsa-ucm-conf/issues

We can resolve it there.

Sounds reasonable.  Less changes in kernel, better :)
