I want to record video from my #Ubuntu desktop or #Firefox browser using a mic through an audio interface. With #OBS I get the video signal alright but I can't get the audio to work. I have the current Ubuntu release (hence #pipewire) and the Pro Audio profile enabled. I also tried #Kooha, to no avail. Just in case it helps, I installed both with #Flatpak.

I have no idea what could be the problem. I can make video calls and play songs, no problem. Any ideas? Happy to take other approaches.
