I've lurked for a while but I finally found a problem I can't solve. I have a Behringer UMC 204HD, on the current version of Pop_OS (which uses Pipewire natively), and I'm using mostly Bitwig Studio. I can't for the life of me get sound out of the 204's outputs.
My OS's audio settings give me a Front L and R and a Rear L and R, but none of those output sound when I try them. I've tried messing around with wireplumber and qwtlgraph with no results. Since the 204 is a commonly recommended interface for Linux, I was wondering if anyone has encountered this issue.
I'd prefer not to switch off Pipewire if possible, since it works so well otherwise.
