Thanks for the reply.
Is audacity recording via pulseaudio?
It's set to "ALSA" for its host interface, and it doesn't seem to offer other options.
Other software like obs-studio works fine. I haven't done a comprehensive survey but I'm happy to try other methods. I doubt this is an audacity bug since even after exiting, it leaves my audio device in a broken state.
Does it communicate with alsa-lib pulse plugin? Or is it the direct ALSA device access? The exact setups are unclear, so it's difficult to guess what's going on.
That is, if you keep arecord running (over pulseaudio), and start audacity in parallel
Good idea . I just tried, and the recording becomes garbled at the precise instant where audacity is started !
Do you mean that the sound from arecord gets garbled? And, did you record with arecord, or with parecord? And if it's arecord, is it over pulseaudio (with alsa-lib pulse plugin)?
without the need of complex sound system setup.
This is already as simple as I can make it .... reboot, run arecord / audacity, and the problem is 100% repeatable.
No, I mean the way to trigger without audacity but only with simple arecord or other command-line sequences.
