@triantares reading the rest of the convo:
- I updated your howto with a few changes (you can see them in the edit button), like pulseaudio not able to be killed without using that command
- can you update the howto to remove not-needed things ? (like the bindings.cfg configuration, setvolume in bullseye is updated now with the fix)
- @PerfMonk has a few improvements too that can be updated on the Howto upgrade Elive Beta from Buster to Bullseye - #2 (or can you @PerfMonk edit the howto to improve it?), like the pre-upgrade install
ah! that was the cause! 
the problem is that the elive tool "audio-configurator" creates this file for compatibility with ALSA 
, ok let me solve that... done
so, @PerfMonk do an "apug" on your bullseye and try the last updated combo in the end of the howto Howto upgrade Elive Beta from Buster to Bullseye , this should solve your audio cards among reboots
