Thanks Raymond,

By default the pin 0x1a if I remerber well, was not connected at all. I
found out that the 0x12 (internal mic) was (override) connected by
default but if I disconnect it, it seems to solution the problem of the
mono sounding front speakers and makes now the front speakers output to
stereo.

Now I have done that much around that stincky crapy el cheapo cheap
(laptop) that I don't remerber even what exactly.

Anyway, now my setup looks like this and I have the subwoofer and front
speakers working and it looks like this :

autoconfig: line_outs=2 (0x18/0x1a/0x0/0x0/0x0) type:line
speaker_outs=1 (0x14/0x0/0x0/0x0/0x0)
hp_outs=1 (0x16/0x0/0x0/0x0/0x0)
mono: mono_out=0x0
inputs:
Mic=0x19
Internal Mic=0x12

The hdajackretask setup :

Pins :

0x12 : Not override > Internal mic
0x14 : Override > Internal speaker
0x15 : Override > Not connected
0x16 : Not override > Headphone
0x18 : Override > Line out (front)
0x1a : = Overrride > Line out (Center/LFE)

In alsamixer I have no trace of an bass speaker but does control :

Master : Only one channel control
Speaker : Set to 00 and no control over
Front : Two channels (R/L) separed controls
Surround : Two channels (R/L) separed controls

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.
