Public bug reported:
Basically, when I boot the computer or restart that process (see below),
the sound appears in top right corner, but it just disappears in a few
seconds, and the sound never works. If I go into youtube on firefox for
example, it just fails immediately and never produces any sound. But
somehow if I go into sound settings during that short period before it
breaks, I can actually hear the sound by clicking on the test thing.
Anyways, it just breaks without ever producing sound besides the sound
settings test.
This is the log from when I restart using `systemctl --user restart
pipewire-pulse`. Not sure if it was already captured or not, but anyways
it's here.
