[Pkg-utopia-maintainers] Bug#1042713: wireplumber: High cpu usage

Package: wireplumber
Version: 0.5.8-2

I have the same issue. Sometimes Firefox seems to hang and I notice wireplumber
eating 100% CPU on one core. Restarting wireplumber fixes the issue and
unfreezes Firefox as well.

I don't have pipewire-libcamera installed. Here are some logs, I restarted wireplumber 14:29:
