Title:
  [Analog Devices AD1988] Headphone jack sense not working

Status in “alsa-driver” package in Ubuntu:
  Confirmed

Bug description:
  When I plug in my headphones the external speakers won't mute automatically. 
Instead of muting the speakers the sound comes from both headphones and 
external speakers.
  If I go to sound preferences and select connector "Analog headphones" 
(instead of Analog output) it mutes both speakers and headphones.
