Title:
  C1E freezes the desktop and sound

Status in The Linux Kernel:
  Expired
Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  After a while of inactivity the desktop freezes and sound hangs in a ~1 sec loop.
  It seems that the interrupt system is caught in a deadlock which is resolved by some external input from mouse or keyboard events. This happens with and without any sound.

  First I suspected the sound system to cause the issue but after some
  investigations and searches for similar issues I found out it is
  related to AMD C1E power saving options. The hanging sound was only a
  symptom.

  WORKAROUND: I reverted all the
  https://wiki.ubuntu.com/Audio/PositionReporting hints and disabled C1E
  in the bios and that solved the problem.

  See also https://bugs.launchpad.net/ubuntu/+source/linux/+bug/509219

  ---- original, but incorrect issue description:

  After a while (minutes) sound freezes the desktop, keyboard input or
  mouse movement fixes it.

  This is independent of the sound source. It happens with Rhythmbox or
  youtube or anything else. When the desktop is frozen, the music/audio
  replays the last second or so, like when an LP/CD gets stuck because
  of a scratch.

  I already tried the https://wiki.ubuntu.com/Audio/PositionReporting
  hints with no success.

  Thanks for your help!
