After one of my daily upgrades on Debian (SID), my sound no longer worked. In only saw a "Dummy Device". Although I no longer have PulseAduio installed and replace it with PipeWire, there still were some artifacts that seemed to have caused problems. NOTE: I could still pair my BlueTooth devices. Only my internal Laptop sound devices did not work!
Here is what worked for me:
- I checked if there was any valuable output with
journalctl -b --no-pager -g pulseaudio. In my case it told me some binaries were no longer available and PipeWire shut down. The culprit was/etc/xdg/autostart/pulseaudio.desktop.
I deleted that file. After a reboot, I did not have ANY sound device to select from. - So, I reinstalled the following packages: gnome-audio, pipewire-pulse, pipewire-audio.
After another reboot, everything was back to normal :-)
