Title:
  headphone jack sense not enabled

Status in ALSA driver:
  Confirmed
Status in alsa-driver package in Ubuntu:
  New
Status in pulseaudio package in Ubuntu:

Bug description:
  bug is present in Ubuntu 12.04 and Xubuntu 12.04 and Lubuntu 12.04.1 64bit 
  alsa-base 1.0.25+dfsg-0ubuntu1 on this machine (64 bit)
  I except Ubuntu to automatically sense the presence of headphones and disable the speakers.  This is not the case, the speakers and headphones play simultaneously.  I must install gnome-alsamixer to manually set the jack sense.  Alsa should have this enabled as the default setting.  This seems as though it should be a very easy bug to fix, though.
