Good morning Dan
I can confirm that by eliminating PipeWire and reinstalling Pulse-audio,
the system returns to work in a regular and perfect way. I therefore
confirm that the bug is specific to Pipewire and you have to work on it,
you can confirm everything to the developers. For specific information I
remember that I use a dedicated sound card that has always been
supported by Linux, namely the RME HDSPE-AIO. Having said that I hope
that you will also work to improve the management of Gnome 40 which
currently on Power architecture is really horrendous.
Thanks for everything
best regards
Maurizio
