Title:
  [HDA-Intel - HDA Intel PCH, playback] Playback problem

Status in alsa-driver package in Ubuntu:
  Incomplete

Bug description:
  The headphone jacket is not recognized. Sound is playing on speakers,
  but when headphones are inserted it keeps playing on the speakers and
  no sound on the headphones.

  Alsa info: http://www.alsa-
  project.org/db/?f=3efa4bd7d30c914b0e423ab3e0334f132dc568af

  I also tried alsamixer, but it does not even show me the headphone
  line. Almost as if it does not exist.
