Title:
  [20ANCTO1WW, Realtek ALC3232, Black Headphone Out, Left] No sound at
  all when headset plugged in

Status in alsa-driver package in Ubuntu:
  New

Bug description:
  Sounds works fine through the internal speakers, but once I plug a
  headset or headphones (I tried two things, in case one was broken) in
  to the audio out, I get nothing.

  Looking in alsamixer, plugging the headset in mutes the 'Speaker'
  output and unmutes the 'Headphone' output, and restores the Master
  volume to its previous headset-in value. Unplugging the headset does
  the opposite (mutes 'Headphone'; unmutes 'Speaker'), as I would
  expect.

  This was working on vivid, so a definite regression, I think.
