  [SATELLITE L750, Conexant CX20585, Speaker, Internal] Playback
  problem, speakers don't work

Status in linux package in Ubuntu:

Bug description:
  Sound works through headphones, but it does not through the speakers.
  HOWEVER, at logon, I can hear the drums sound, so it's not a hardware issue.
  SOMETIMES, executing "amixer -c0 set Headphone unmute 100%", as adviced in [1], works temporarily.
  I had same issue with Fedora 22, see [1] for context.
