Additional comment: The AppImage for Audacity 3.0.4, as downloaded from audacityteam.org sees all available devices, including pulse. Not sure what "default" was pointed at, but the pulse device..., the sysdefault, and another USB connected device all worked as recording sources.

This still is an issue. Didn't get stable to work. Only got pulseaudio to work by installing edge and not allowing ALSA even against it complaining. Even thought record is disabled it works...
