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 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1302090 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.
