I'm not on my machine right now but I have seen this related with the video display. A lot of times I put music then go away, after some minutes my monitor turns off the screen, if I come back and move the mouse just so the screen turns on again I ear my audio jump. Sometimes it just stops and have to stop/pause song in mpd. But not related directly to mpd, have seen it with chrome/Firefox also. Will share dmesg later when I'm on my machine.
