I think so in your case, but may take time for a reply. In your message to the dev's, include a link to this forum thread, as that will help to explain the problem and what has been looked at so far.
Maybe after the Christmas and New Year holiday's over maybe more users will be back here and some bright spark may think of a potential solution.
@Rigge, can you download Pop! OS 21.10 and boot it live to see if the sound issue is gone ? Just for testing purpose because i know they use kernel 5.15.8
Wasn't sure if this was a nod to me!
Give yourself ownership of /etc
sudo chown [your user name] etc
then create a folder and call it 'pulse off' and drag the pulse folder into it.
Now add all the ALSA packages you can find in Synaptic Package Manager but not the ones for Jack or Pulse or OSS. Also install QAS Mixer, QAS Config plus one more whose name escapes me. Launch QAS Mixer and you should see your audio device at bottom of mixer window unchecked. Check it and you should hear a slight pop indicating you now have sound.
thanks guys, i think i am done... its too complex for me, i choosed an easy distro because i don't want to have to dive into all that, i am not a geek.
Gonna wait the answer of the support
Do not feel too bad, actually. I am all over the forum being complex and being simple, too. And Sound Issues drive me up the wall. Makes my head spin.
I am more than happy to dump those off on better users like @zabadabadoo or @swarfendor437 .
