Bug#1042713: wireplumber: High cpu usage

[Jonathan Kamens]

I just encountered this again, and sound (both input and output) weren't 
working while it was going on. I did `systemctl --user restart pipewire 
pipewire-pulse` and wireplumber stopped spinning and sound started 
working again. Just posting this update in case somebody else stumbles 
across this bug report and is looking for a workaround.
