Ubuntu Studio lead here. We have been very closely watching the development of PipeWire as it is of interest to a large amount of our user base in the Audio Production world.
Please note that PipeWire, in its current iteration, is meant to be a drop-in replacement for both PulseAudio and Jack sound servers. Having PulseAudio and PipeWire (specifically the pipewire-pulse package) installed simultaneously is asking for trouble as the PulseAudio implementation of PipeWire is feature-complete. I'm actually surprised that the pipeiwire-pulse package doesn't have a "Provides:" or "Conflicts:" line for PulseAudio as it's literally a drop-in replacement.
For this reason, this is *strongly* looking like a support request more than an actual bug and I'm tempted to close it as invalid (support requests are not allowed on a bug tracker). Either that or a bug against the pipewire source package for not having the "Provides:" or "Conflicts:" lines mentioned above.
TL;DR: pipewire-pulse and PulseAudio should *not* be installed at the same time as they serve the same function and applications don't know the difference.
