Finally finally finally I got that salad to work but not the same way, here the details :
In fact they are to pins disconnected that I had to connect, the 0x1a and THE 0x18, the connections in hdajackretask are now : 0x1a = Line out (back) 0x18 = (Center/LFE) Which gives in alsamixer : Master = Master fonction. Headphone (Headphone) = Adjustable volume for the headphone jack (first one). Headphone (Headphone 1) = [00] Not adjustable (probably the headset jack ?). Speaker (Speaker) = [00] Not adjustable. Front (Front) = Adjustable and corresponding to front speakers (if on 00 you ear only the subwoofer). Surround (Surround) = seems to correspond to the subwoofer (if on 00 you ear high front frequency). Mic (Mic) = Mic adjustable. Mic Boost (Mic Boost) = Adjustable but no idee what for. Auto-Mute (Auto-mute Mode) > (line out, speaker, disable) = If line out selected it mute all speakers, if speaker selected it mute only the "tweeters" but the subwoofer is still active. So I hope that it will be usefull to others that were fyghting to get that "crap" working. P.S. I didn't try if the headset nor mic are fonctionnal but the headphone are, no problem. -- You received this bug notification because you are a member of Ubuntu Touch seeded 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. Attached is the alsa-info.sh output for my machine.
