Public bug reported:
If Banshee or Rhythmbox is left playing in the background they will
randomly stop playing in the latest builds of Ubuntu 12.04. Starting a
new piece of music usually fixes the problem. If left to its own
devices, the music will start playing again at some random time, at some
random position. This problem exists on both my desktop machine (custom
built Intel machine) and my laptop (Macbook 5,1). It has been happening
for several months now.
I became frustrated enough to load up pulseaudio in debugging mode. The
log shows that when the music player just finishes playing one piece,
and tries to start the next piece, you see something like this:
