if you look carefully, you should notice that 0x26 is not any detectable
pin complex in vt1802
Node 0x26 [Vendor Defined Widget] wcaps 0xf00000: Mono
/* Mono Out */present = snd_hda_jack_detect(codec, 0x26);
parm = present ? AC_PWRST_D3 : AC_PWRST_D0; if (spec->codec_type ==
VT1802) { /* PW15 (33h), MW8(1ch), MUX8(3ch) */update_power_state(codec,
0x33, parm); update_power_state(codec, 0x1c, parm);
update_power_state(codec, 0x3c, parm);

I don't understand how this patch can fix the problem since mic jack is not
retaskable and all pin complexes are hardcoded in set widget power state

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.
