Hi!, i’m having some issues with pipewire on a new instalation of cachyos (new user!), when OBS (Both, the Flatpak and the AUR obs-browser) is open capturing audio (or the screen via pipewire, idk) pipewire stops and restarts constantly, sometimes making OBS crash.
The behavior i see is that it deletes all the audio sources and then re-adds them every 2 seconds except any virtual sources I’ve created (yes, I’ve tried to start the system without them, no luck), making it impossible to capture and listen to audio, this stops when i close OBS or i restart pipewire and wireplumber via terminal but don’t dare to touch the KDE’s volume applet or it’ll go haywire again.
I’ve tried different kernels, Cachy, CachyLTS and Zen (my last distro used Zen).
I’ll add some logs that might be relevant:
OBS before a crash:
