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 L745, Conexant CX20585, Speaker, Internal] No sound at all

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I don't have any audio output through the laptop's internal speakers
  but I get audio fine if I plug in external speakers.

  I can get audio working briefly by running

  sudo hda-verb /dev/snd/hwC0D0 0x1f SET_POWER_STATE 0

  as suggested at 
  http://lkml.iu.edu/hypermail/linux/kernel/1301.1/02917.html

  but it doesn't last very long before the audio turns off again.
