1) When you say without any patch means without any change through
hdajackretask ?

2) With connecting the pins through hdajackretask ?

Anyway, the first question that would be good to solve is to know how
many loudspeakers are effectively in that box because I don't realy
understand what front and surround speakers are in this situation. As
far as I know they are 3 : R/L front speakers and the subwoofer. So
where is that "surround" coming from in alsa ?

I will try to find a schemes of that setup to know exactly how is that
box configured.

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.
