Title:
  Mythbuntu improperly supports Realtek ALC889A audio

Status in “linux-backports-modules-2.6.31” package in Ubuntu:

Bug description:
  I am using a Gigabyte MA790X-DS4 motherboard that has built-in Realtek
  ALC889A audio.  Mythbuntu detects this as ALC885 and the sound
  channels do not work properly.  For example:

  1) Left and right sound channels are reversed.  (applies to analog outputs only; S/PDIF and Toslink works correctly)
  2) When running speaker-test, the center channel activates with the left channel.
  3) When running speaker-test, the center, side, rear, and subwoofer channels do not work.
  4) When a stereo source such as music in VLC is played, all 8 channels are active and appear to play the same signal.

  Note: When using the S/PDIF or Toslink outputs, everything works
  correctly.  Stereo sources are transmitted through the link as
  2-channel PCM audio.   AC3 and DTS passthrough also work fine and
  carry all 6 (or 5.1) channels.
