Title:
  [MS-7968, Realtek ALC1150, Black SPDIF Out, Rear] Underruns, dropouts
  or crackling sound. Test tones work but sound immediatly returns to
  poor quality after completion.

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  Using digital audio output on Intel driver.
  Sound from games is barely decipherable over the distortion/crackle. Playing 
test tones (left/right test and on bug report) work fine but the noise returns 
when the clips are completed.

  Tried tsched=0, hda fix 1 and hda fix 2. no luck yet
  When first added tsched command, it blurs the screen and no audio devices are 
available. remove, restart, re-add and screen and audio back but problem still 
present (maybe just spelt wrong first time?).

  Help appreciated.
