Title:
  [SATELLITE L750, Conexant CX20585, Internal Speaker] - Sound from
  internal speakers fails after a while.

Status in “alsa-driver” package in Ubuntu:
  New

Bug description:
  The sound works ok and after a while fails/disapears. Can not identify
  what I did, however it was ok month or two ago.

  I occassionally update recommended updates. My system uses new
  backported kernel that is not original to Ubuntu 12.04, however with
  the original updated kernel (the one that is supposed to be current
  for my Ubutmu version) it also does not work.

  Surprisingly the internal speakers are the only that suffers with this
  problem. The HDMI sound works perfect and also headphone jack works
  well too.

  I have checked mixer controls with alsamixer and no, I do not have
  muted outputs. The only weir think I observer is that by default there
  is enabled controll that has name "Auto-Mute mode". Even when I
  manualy disable this controll when the speakers playing ok, the bug
  appears too after a while.

  I gues that this bug is most likelly related to this one:
