this is not best config since assign speaker and subwoofer to same DAC
mean no spearate volume control for subwoofer and you need those config
(type SP) which DACs are assigned to speaker and subwoofer

the easy way is to change the headset as [N/A] by hdajackretask

or

change badness of those config (type SP)

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.
