alsa-project/alsa-ucm-conf issue #471 was opened from beatboxa:

I had previously gotten my MOTU D828 working with UCM. I recently used Ubuntu 24.04's software updater, and now my UCM appears to have stopped working. The UCM files are still present in the directories where they previously worked.

The output of spa-acp-tool -c 0 -vvvv info now begins with the following:

``` UCM is not supported for this USB device (MOTU 828 at usb-0000:59:00.0-6, high speed @ USB07fd:000e) error: failed to import hw:0 use case configuration -6 UCM is not supported for this USB device (MOTU 828 at usb-0000:59:00.0-6, high speed @ USB07fd:000e) error: failed to import 828 use case configuration -6 UCM not available for card 828 Check for file: /home/beatboxa/.config/alsa-card-profile/mixer/profile-sets/default.conf Check for file: /home/beatboxa/.config/alsa-card-profile/profile-sets/default.conf Check for file: /etc/alsa-card-profile/mixer/profile-sets/default.conf Check for file: /etc/alsa-card-profile/profile-sets/default.conf Loading profile set: /usr/share/alsa-card-profile/mixer/profile-sets/default.conf Parsing configuration file '/usr/share/alsa-card-profile/mixer/profile-sets/default.conf' Parsing configuration file '/usr/share/alsa-card-profile/mixer/profile-sets/9999-custom.conf' Looking at profile input:analog-stereo Checking for recording on Analog Stereo (analog-stereo) Trying front:0 with SND_PCM_NO_AUTO_FORMAT ...

``` And goes on from there.

Previously, my configuration worked, and is tracked in this thread: #https://github.com/alsa-project/alsa-ucm-conf/pull/416

Is there some little thing I need to change to get UCM working again?
