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.
