for external 5.1


==> lo_type=2, wired=0, mio=1, badness=0x20
  multi_outs = 15/16/0/0 : 2/3/4/0 (type HP)
  out path: depth=3 '02:0c:15'
  out path: depth=3 '03:0d:16'

mio = 19/0 : 4/0
   mio path: depth=3 '04:0e:19'

driver need to add mio path for mic and  treat two hp at same location
to support 5.1

  spk_outs = 14/18/0/0 : 2/3/0/0
  spk path: depth=3 '02:0e:14'

Title:
  Dell Alienware 14, Speaker sound output is mono until a headphone jack
  is plugged

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  Here's the required release and package information:

      Description:    Ubuntu Trusty Tahr (development branch)
      Release:        14.04

      Package: linux-image-extra-3.13.0-19-generic
      Version: 3.13.0-19.40

  When playing audio through speakers on my Alienware 14 2014, the sound
  output is in mono until I plug a headphone in any of the two available
  headphone jacks (obviously, the auto-mute option must be disabled).
  When I do so, the sound starts to play in stereo.

  I would love the sound output to be stereo by default and not be
  forced to plug anything to achieve that.

  Attached is the alsa-info.sh output for my machine.
