The codec and the wiring on this laptop are identical to N75SF, which I
recently purchased.
Attached is the draft patch that fixes most of the troubles and adds more
controls.
Features:
* Automute toggling for headphone plug
* HP jack retasking for mic-in/hp-out/line-out/line-in.

It worked on the 3.0 kernel version. But the most weird is that even if
I do the changes you did in the hda_analyser tool to switch on the

Can you tell what commands you added to rc.local?
I'm still running 3.0.0-12 as it makes no difference for me.

Since I did an update of my kernel (linux 3.1.4) on Arch Linux, this solution
doesn't work anymore ...
I tried to do exactly what you did in the hda_analyzer tool, but I can't get
the subwoofer working.
Before, I put your 2 commands in the rc.local file, and it works
perfectly.
Any idea ?

Thanks a lot Denis, it works perfectly on Arch Linux ! I just did what
you said in the post 10, but I did a "pulseaudio -k" before, otherwise I
have the same message as you.

You probably need to kill pulseaudio:
echo autospawn = no >> ~/.pulse/client.conf
killall pulseaudio
Also check with
sudo fuser -v /dev/snd/*
for other processes currently using sound cards.

Nice! So pin 0x16 is the subwoofer pin then. Could you try setting the
pin configuration default to 0x99130112 for pin 0x16 and see what
happens? How this can be done is written in this document:

Finnaly I managed to switch subwoofer on with hda_analyzer tool.
Here exatct steps to make subwoofer on
Node[0x16] PIN - Output amplifier - Val[1] - unmute, check Widget Control - OUT
Node[0x14] PIN - Check Widget Control -IN
Node[0x0e] AUD_MIX - Input amplifier - Val[3] - unmute

Ok, then there is no obvious way of getting this working, unfortunately.
Chances are that some kind of hidden undocumented processing
coefficients have to be enabled for this to work. You could try playing
around with hda-analyzer (the hda-analyzer tool is available in the snd-
hda-tools package yo
I tried this before. When I try "Digital Stereo Duplex (IEC958)" or
"Digital Stereo Output + Analog Stereo Output" the sound from ordinary
speakers stops and in the same time there is no any sound from
subwoofer.

Hmm, so it's connected to the SPDIF out? If you select "Digital out" as
your profile (on the hardware tab of "Sound settings"), will it start to
play through your subwoofer (but possibly stopping to play through your
ordinary speakers)?

Interesting, I've never seen an Internal speaker + external subwoofer combo
before. Question how this is connected from the Codec's point of view.
Would you be willing to do some testing? If so, please download and install
snd-hda-tools from ppa:diwic/misc. Then run "sudo hda-jack-sense-test -a"
