Public bug reported: Recently (since yesterday), during audio playback ("Videos" app, Chrome (google music)) the audio will go from perfectly clear to complete static white noise. This usually starts about 5 seconds into playback and can last from about 10 to 40 seconds before returning to normal.
Playing with volume levels in the ubuntu audio mixer it sounds like the audio has been auto-amplified and that is clipping and causing static, but that's just a guess. I've tried playing with a few pulse options to change things but can't find anything which makes it any better. I'm using analogue output on a usb speaker (dell soundbar), and have not had problems since buying it or the rest of the pc, this seems to have occurred fairly recently.
