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.
