Title:
  [Macmini7,1, Cirrus Logic CS4208, Green Headphone Out, N/A] No sound
  at all

Status in alsa-driver package in Ubuntu:
  Incomplete

Bug description:
  The sound is played from the internal speaker only.
  Funny thing is that when I disconnect the jack the sound device in sound settings goes from Speakers to Headphones (which is the opposite) and the sound stops playing even from the internal speaker.

  It looks like the output switch is reverted to the jack indicator.
