do suvpbwoofer really work since both speaker and subwoofer connect to same audio output ?
to add volume controls to speaker and subwoofer , either use hda Jack retask to remove one headphone jack or modify driver to increase badness when there are two headphone Jacks and two speaker pins ,but only three audio output when cfg->line_out_type == auto_pin_hp_out since Def assoc of second headphone Jack is larger than that of subwoofer (lower priority to assign volume control/audio output ) this force driver to assign audio output/volume control to two speakers first -- 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.
