Always "pulse-rust".

I did not have pipewire-pulse installed.
Installing it and starting the daemon with "systemctl status --user 
pipewire-pulse.service" fixed the video issue, but there was no audio 
from the browser.
Actually restarting the gnome session restored the audio too.

While this is not a serious issue, I think that the failure mode is 
non-obvious enough that something should be changed to prevent this 
situation.

Are there any other non-obvious packages that should be installed?
E.g. I see that pipewire-pulse recommends pipewire-alsa, but I have no 
idea of what I would need it for.

BTW, after installing wireplumber now something emits an annoying beep 
when I raise/lower the volume with the keyboard volume keys: how can 
I disable it?
