Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.7-rc1 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

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

Status in linux package in Ubuntu:
  Incomplete

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.
