Using PipeWire as audio server
When I updated to the latest version of Debian, I also started to use PipeWire instead of PulseAudio.
To enable this, this meta-package install all necessary:
sudo apt install pipewire-audio
In addition to this, if you need to restart the audio service, you can use this command:
systemctl --user restart wireplumber pipewire pipewire-pulse
