Do I understand correctly that, if you remove /var/lib/alsa/* before the reboot, the mic works always?
I have to remove the devices *and* clear out the directory. Under the above conditions, after the first boot, the mic works.
OTOH, if /var/lib/alsa/* is present, the mic is always broken?
That does seem to be the case.
If they are related, at the 1st boot, run "alsactl store", and "alsactl restore". Does it break the mic recording?
The above was an interesting test. You obviously know your domain well because it did break the mic. I tried to anticipate what you may need so I captured some additional data. I also compared "alsactl store" .cfg file after boot 1 vs boot 2: they're identical. ::: /var/lib/alsa - before restore ::: # ls asound.state card0.conf.d/ # ls -la * -rw-r--r-- 1 root root 0 2022-04-01 22:26 asound.state card0.conf.d: total 0 drwxr-xr-x 1 root root 0 2022-04-01 22:27 ./ drwxr-xr-x 1 root root 48 2022-04-01 22:27 ../ root@zoom:/var/lib/alsa ::: /var/lib/alsa - after restore ::: # ls asound.state card0.conf.d/ # ls -la * -rw-r--r-- 1 root root 0 2022-04-01 22:26 asound.state card0.conf.d: total 0 drwxr-xr-x 1 root root 0 2022-04-01 22:31 ./ drwxr-xr-x 1 root root 48 2022-04-01 22:31 ../ ::: Restore w/-d ::: alsactl: set_controls:1499: device='hw:0', doit=0 alsactl: set_controls:1511: card-info-id: 'sofsoundwire' alsactl: set_controls:1546: list count: 67 alsactl: set_controls:1574: maxnumid=67 maxnumid2=65 alsactl: set_controls:1579: more controls than maxnumid? alsactl: set_controls:1587: result code: -11 alsactl: sysfs_init:45: sysfs_path='/sys' alsactl: set_controls:1499: device='hw:0', doit=1 alsactl: set_controls:1511: card-info-id: 'sofsoundwire' alsactl: set_controls:1587: result code: 0 -- You are receiving this mail because: You are on the CC list for the bug.
