Bug#972689: Sound output is only working randomly

[Karsten]

Package: pulseaudio
Version: 12.2-4+deb10u1
Severity: important

Maybe this this bug is already reported, but i could not find an open or fixed solution for it.
Maybe this is similar https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=787286
or https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=972654 (pipewire is not installed)

It is not possible to use Debian 10 as desktop environment, because sound is only sometimes available.
Alsa is working, because i get a sound with some sound like
aplay -D hw:0,1 /usr/share/sounds/sound-icons/canary-long.wav
But when i try speaker-test i can see in pavucontrol that there is signal, but even switching it to the correct output
the sound keeps dead.

I have no idea what can be done and why it is working only sometimes?
I can only say that i have to boot Debian 8 to get always sound!
But Debian 8 is somehow outdated now ...

Please help - this is more than annoying.

Regards
karsten
