** Description changed: Recording through internal microphone produces crackling noise on playback. This happens regardless of settings for input device using alsamixer. When using the ubuntu-bug wizard I said the first test passed because the audio was remarkably better than the 2nd but there was still minor crackling, so I am not sure how to do some ALSA only tests to verify the culprit really is PulseAudio, please advise. + + Update: I just discovered arecord and did a test. The crackling is still + present with arecord.
