USB soundcard crakling ( bit redux ) and then no audio. Ports switch on their own
pipewire
Compiled with libpipewire 0.3.56
Linked with libpipewire 0.3.56
Manjaro Linux
KDE plasma
5.19.1-3-MANJARO
Description of Problem:
When playing with audio inputs->processing->output, after a random amount of time there is a screech sound after which the sound turns off. Sounds like bit reduction at times or ringing.
Then usually after that the outputs switch. Normally motu mk4 output to main would be on playback_AUX0, but it changes to playback_AUX16 (not the connections but when manually patching it to 16 17 the sound its there till it crashes again)
Same goes for the capture port, it varies between capture_AUX0 and capture_AUX16
How Reproducible:
Install pipewire-* , setup the configs. Fire up Carla at 128/48000. Play for a bit and wait for the crashes to happen
Actual Results:
Audio breaks partially (distorsion , ringing...) or completely and switches AUX

Tried to use the configs, changing sample rate & buffer. nothing seems to work. I've also noticed how plasma-pa appears and disappears when opening the volume control panel on KDE Tried also to compile from the repository with no difference

Please tell me if I can provide any further details since I would love to work with my motu ultralite mk4 on my system
