Janne already has a copy of this sample, but so that others can take a look: ​http://www.miffteevee.co.uk/filebin/mjpeg_test_sample.mov

Shifting this back to 0.21 on the off chance that someone does get a moment to look at the issue. The video is similar to that produced by many digital cameras so it's not an uncommon source.

Summary: Audio playback problem with MJPEG file → Audio playback problem with alsa and 8000 Hz, 8bit mono audio

sample has only disturbed audio with alsa audio out, probably a regression from the multi channel audio commit.
