OBS Studio - Audio capture doesn't work on Fedora 34

Project Discussion

OBS Studio’s audio capture feature degrades significantly of Fedora 34. When using the pulseaudio capture from the Flatpak application, the audio is very choppy and rarely comes through.

This is not an issue with the input device itself. I confirmed that audio recording works fine with Cheese.

I replied on OBS Forums - changing my system’s default microphone to the desired mic worked. Audio can be captured through the “Mix/aux” audio input.
