Comment 37 for bug 410948

Having the same problem here. Mine is a Gateway MT3707 updated to Karmic from Jaunty. Also, after replacing "merge" with "ignore" in analog-output.conf there's a nasty clicking sound instead of the expected sound in the first two steps. For example, starting as muted I begin playing an MP3, then step up the sound once and I hear some clicking. Step up again and the clicking gets worse. Step up again and the clicking disappears and the music finally starts coming through. Had to undo changes to analog-output.conf because of that.
