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. Takashi
