He, here the alsa-info output.
>From what you can see, the codec reports controls up to 0x3c; there's
almost another control at 0x3e which I dumped :
Node 0x33 [Pin Complex] wcaps 0x40050c: Mono Amp-Out
Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1
Amp-Out vals: [0x00]
Pincap 0x00000010: OUT
Pin Default 0x501701f0: [N/A] Speaker at Int N/A
Conn = Analog, Color = Unknown
DefAssociation = 0xf, Sequence = 0x0
Misc = NO_PRESENCE
Pin-ctls: 0x00:
Power states: D0 D1 D2 D3 EPSS
Power: setting=D0, actual=D0
Connection: 1
0x3e
[ 467.214734] Widget #3e -- ANALOG MONO AUDIO MIXER
[ 467.214735] Input from widgets : 0x1c
[ 467.214738] Does NOT support unsolicited response
[ 467.214739] Out amp NOT present
[ 467.214741] In amp NOT present
The extra widget 3e is a stereo-to-mono mixer, input from mixer 1c and
output on 0x33.
Widget 0x33 is NOT detected by alsa code because it's marked as no-connection
output and because it takes its input from out of range widget 0x3e.
With the 2 patches dropped in alsa-devel, the output paths become following :
[ 1378.923620] ALSA patch_via.c:1861 output-path: depth=4, 08/34/14/24/00
[ 1378.923625] ALSA patch_via.c:1861 output-path: depth=4, 08/21/14/24/00
[ 1378.923820] ALSA patch_via.c:1861 output-path: depth=4, 09/3c/1c/33/00
[ 1378.924287] ALSA patch_via.c:1861 output-path: depth=4, 08/35/15/25/00
[ 1378.924291] ALSA patch_via.c:1861 output-path: depth=4, 08/21/15/25/00
So, the 0x8 DAC is shared between HP and front output, and DAC 0x09 is used for
surround.
It works, even it shows as 4 channel audio instead 2+1 one... I don't know if
it's possible to make it
showing as 2+1.
Besides the bugfix patch (the first one posted in alsa-devel) the patch
are :
skip 0x3e control connecting 0x33 directly to 0x1c
force 0x33 to line output
force 0x24 to line output, otherwise auto_parser take it as a speaker and
discards it

Title:
Asus G75v internal Subwoofer not working; alsa not aware of it
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
The internal subwoofer on my Asus G75v laptop does not work in
(k)ubuntu (e.g. no sound).
The audio setup (KMix>Settings>Audio Setup>Audio Hardware Setup) does
not list a profile for 2.1 audio.
I see the following profiles in the drop-down list:
Analog Stereo Duplex
Analog Stereo Output
Digital Stereo (IEC953) Output + Analog Stereo Input
Digital Stereo (IEC958) Output
Analog Stereo Input
Off
I've searched for a solution to this and have not found anything that
works. Any help would be appreciated.
