[SATELLITE L750, Conexant CX20585, Speaker, Internal] Playback
problem, speakers don't work
Status in linux package in Ubuntu:
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 , works temporarily.
I had same issue with Fedora 22, see  for context.
