Some times no sound after login into Mate

[Christian Schoepplein <chris@schoeppi.net>]

Hi,

with Debian 11, latest updates and backports enabled, I very ofthen have the 
problem that no sound is available after login into Mate. I normaly use a 
headset for work and when this headset is plugged in all is fine. But 
sometimes, when I want to use the laptop without the headset, no sound is 
there after login into Mate. Sometimes a reboot fixes this issue, very 
ofthen this does not help. To get sound back the only working fix is to 
plugin the headset and plug it of again.

Strangely this whole thing is totaly random. Sometimes its working wit or 
without a headset  for days, but e.g. this morning even two reboots did not 
bring sound back with no headset plugged in.

Is there a reproducable way or configuration I can have sound in Mate in 
all situations and where it does not matter if a headset is plugged in or 
not? Is this another bad issue with pulseaudio and might a switch to 
pipewire help?

Ciao and thanks for any helpfull hint,
