Added a screenshot of the waveform of the glitches.

Created attachment 129350 [details] tgz containing sine.wav, silence.wav, recorded.wav Attached in the .tar.gz are 3 files: - sine.wav: 30-second sine wave - silence.wav: 0.1-second silence - recorded.wav: the glitched recorded result. How to reproduce: - run: paplay sine.wav - While the sine wave is playing, in another terminal run: parec -d $MONITOR --file-format=wav > recorded.wav where $MONITOR is your monitor device, in my case it's alsa_output.pci-0000_00_1f.3.analog-stereo.monitor - While recording, in another terminal run: paplay silence.wav - stop parec with Control+C - stop the paplay sine.wav - Listen to recorded.wav: you should hear glitches similar to my recorded.wav. The sine wave plays, but really short periods of silence are inserted. Some more interesting things: - If you play silence.wav many times, you get more glitches in the recording. Every play seems to trigger 1-2 glitches. - Any sound playing triggers the glitches - system sounds for example.
