speaker and subwoofer should assign DAC(Volume) first instead of two
headphone by increasing badness for (type HP) when there is no line out
if (!spec->no_multi_io &&
cfg->hp_outs && cfg->line_out_type == AUTO_PIN_SPEAKER_OUT)
if (count_multiio_pins(codec, cfg->hp_pins[0]) >= 2)
spec->multi_ios = 1; /* give badness */
+if ((cfg->speaker_outs == 2) && (cfg->hp_outs == 2) && (cfg->line_outs == 0))
+ if (cfg->line_out_type == AUTO_PIN_HP_OUT)
+ badness++
/* re-count num_dacs and squash invalid entries */
spec->multiout.num_dacs = 0;

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.
