Switching audio device on pavudevice switches to non existent device "Unknown output".
In pavucontrol, if I try changing output device, the current device ends up showing "Unknown output" and audio output stops.
This also means there is no way to change back to a real device.
The only solution is to restart whichever program I have done this to.
I am using Ubuntu 21.04 64 bit, with upstream pipewire PPA.
