I installed Debian Bullseye: I have to correct myself, sound is NOT working out of the box but I needed to add my UCMv1 profile in /usr/share/alsa/ucm/ and reboot once and after a positive sound test, I removed my UCMv1 profile and the sound keeps working over reboots.

It means that the mixer setup saved in /var/lib/alsa/asound.state is applied after the reboot and it isn't overridden again by UCM, so it keeps working (at least until the change is needed). It's still interesting how ucmv1 got in place although alsa-lib 1.2.2 is used... UCM profile directories were empty beforehand?

I attach the alsa-info reports from Debian with sound working and from Tumbleweed.

Could you run "alsactl -f alsactl.out store" on the working Debian system, and copy the generated alsactl.out file to TW, restore it via "alsactl -f alsactl.out restore"? At best, copy user UCMv1 profiles into ucm2 directory as-is, restart the session, then run alsactl restore above. -- You are receiving this mail because: You are on the CC list for the bug.
