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.
