Public bug reported:

When I adjust the Balance or Fade slider in Sound Settings, any music
that is currently playing becomes corrupted with beeps and clicks until
I stop and restart the music. A screencast is attached.

This happens while playing music using Totem, VLC, and Amarok in Ubuntu
12.04 and Ubuntu 12.10.
