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)?

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.

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 you already installed), trying to activate different pins in different ways and see if you can get something out of it, but I wouldn't bet on it.

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
Node[0x0b] AUD_MIX - Input amplifier - Val[11] - unmute and set its slider approximately to the middle (this controls volume of subwoofer)
All above make it to switch on.
Node[0x0d] AUD_MIX - Input amplifier Val[3] - this checkbox amplifies suboofer and improve a little sound quality.
I don't know how to make this adjustments to apply automatically as on system reboot everything restores back to the state of disabled suboofer
But there is some problem still exist. As that as I noted soobwoofer sounds not actually as it suppose to be. It plays full range of frequencies and as I hear it parallelled to right channel. When I change balance to left it silence along with rigth channel. In Windows it plays only low frequences and sounds independently from front speakers' balance. I will continiue my attempts with that.
Also there is a MusicNow application (analog of ExpressGate) which boots instantly and provides web surfing and music playing capabilities. It is based on Splashtop OS. This OS based on linux and it boots from Window partition. In its folder bunch of squas

You probably need to kill pulseaudio:

Also check with

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 ?

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 subwoofer, it doesn't change anything for me ...

- Patch against 3.1.6. Draft. Still needs some testing and cleanup. See comment. Edit (6.0 KiB, text/plain)
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/
* Subwoofer amp toggling (off in 2 channel mode => saves battery)
* LFE volume regulation
Those retarded ‘genius’ guys from asus decided to wire the internal mic to the jack on the codec that can be configured as line-out, while external mic can only work as a mic.
Sensing of subwoofer presense doesn’t work yet. I just couldn’t make sense how it works: it’s not acpi, not codec’s GPIO, not regular pin presense of PIN 0×16.
I'm cleaning up the code before sending it to alsa devel.
external mic-in, spdif and line-in of HP pin needs testing, I don't have the hardware along with me at the moment. If someone can do it - plz drop me a note, so that I can fix it.
Patch is against kernel 3.1.6 (tested in Agilia Linux, I don't use ubuntu/kubuntu any more, sorry)

@Rene Arts: It requires to recompile the kernel. Get the kernel source, patch -p1 < nx5sf.patch, compile and you are done. Agilia linux already has this patch in stable, not sure about ubuntu.
It is tested with 3.1.6 and 3.1.8 kernels. 3.2 requires some forward-porting which I'll do later.

To get the subwoofer switched on you can run this python script (created by HDA analyzer):

Hello,
I tried your script stefano, but it doesn't work for me. I haven't any error (I just have to launch it with python 2.7, if i don't I have some errors), and I tried to debug it but I don't understand why it doesn't work...
ArchLinux 3.3.2
Alsa 1.0.25
Pulseaudio 1.1-2
I have to add that before I passed to Linux 3.0 I could clone the right-speak out to go to the subwoofer, it wasn't a clean fix but it was temporary. When I upgrade my kernel to the 3.0 version, it didn't work anymore.
Many Thanks for your script ;)

Hi,
I've spent some of today analysing this issue. It was a little sad that nobody picked up Andrew's patch upstream, but writing model parsers are deprecated today.
Anyway, I believe there is a simpler solution, so can you please try to edit /etc/modprobe.
options snd-hda-intel model=asus-mode4
...reboot to test. If this does not work, follow the instructions here: https:/
Now try these new drivers in combination with the above configuration file change.
Also note that you might need to raise the "Bass Speaker" volume in alsamixer as well.
If any of these approaches help you (and does not cause any other regressions), please respond with your alsa-info ( https:/

Thank you, it works !
But the problem is the same as before I upgraded to Linux 3.0 : the right-speak out is cloned to send a signal to the subwoofer, so these two outs are not separated.
It does that the rendering is not as good as that I have in Windows.

So, if you want automatic LFE remixing, that should be possible through PulseAudio:
First, add a new profile for 2.1 by adding this section to /usr/share/
[Mapping analog-surround-21]
# Note that the line below should NOT be changed to surround21.
device-strings = surround40:%f
channel-map = front-left,
paths-output = analog-output analog-
priority = 7
direction = output
Second, make sure this line is present in /etc/pulse/
enable-lfe-remixing = yes
Then restart pulseaudio (run "pulseaudio -k" in a terminal), then select the new profile in the sound settings.
I haven't used LFE remixing myself, so not sure how well it works, but worth a try :-)

Same here as Craig, but with 11.10. Only the right channel is sent to the subwoofer: can't find the surround profile. I tried the other driver which David suggested, but then sound doesn't work at all. It's a pitty Asus doesn't supply some info to get it to work.

@Craig, in 12.04 you would have an entry saying either "Analog Output" or "Speakers" (make sure headphones are not connected). Select that one. What entries do you have in the "Mode" combobox?

I updated to 12.04 the last days and got stuff up and running again. With the described methods still only the right channel is sent to the subwoofer (also applied the pulseaudio modification). In contrary to with 11.10 I now can select the 4 channel options: testing the speakers gives correct results on the front speakers, and rear right on the subwoofer.

I tried Simone's solution as well. MPD now plays the left and right channel via the subwoofer (and off course the front l+r work). Though some other players like Spotify, Rhythmbox only play via the front speakers. In the sound configuration menu the speaker test plays as it should (front l+r and sub). So I think we're quite close to a good and working solution :)

I tried the solution by David Henningsson and Simone Esciana and it is almost working, i.e. the sound configuration profile for 2.1 is present and when testing, some white noise comes out of the subwoofer. My problem is that no program (Rhythmbox, Clementine or audio from Chrome) seems to send out anything to the subwoofer.
I have an Asus 76VM
Great work so far!!

I have an Asus N56VZ laptop on ubuntu 12.04.
My subwoofer wasn't working (i could only hear some noise from it).
I tested:
1. Post #8: Setting the pin configuration default to 0x99130112 for pin 0x16
--> No changes.
2. Post #34:

options snd-hda-intel model=asus-mode4
--> No changes
3. Post #34: I updated to alsa-hda-
--> No changes
My ALSA-INFO: http://
4. Finally, it seems that my subwoofer is connected to a different PIN.
I installed snd-hda-tools:
#sudo apt-add-repository ppa:diwic/hda
#sudo apt-get update
#sudo apt-get install snd-hda-tools
#sudo hda-jack-sense-test -a :
*** Without subwoofer:
Pin 0x1e (Black SPDIF Out): present = No
*** With subwoofer:
Pin 0x1e (Black SPDIF Out): present = Yes
So I retested an adapted post #8:
#sudo echo 0x1e 0x99130112 > /sys/class/
#sudo echo 1 > /sys/class/
--> it gave me the same result as many of you : subwoofer worked but seems to be plugged with right channel...
--> I set the mode to "Analog Surround 5.1 output" in the sound settings panel and now it seems to work perfectly...
I uninstalled alsa-hda-
I removed options snd-hda-intel model=asus-mode4 in /etc/modprobe.
Finally, on a fresh install, to make your subwoofer work on Asus N56VZ, you would have to:
a. Add to rc.local :
echo 0x1e 0x99130112 > /sys/class/
echo 1 > /sys/class/
b. Add options snd-hda-intel model=asus-mode4 in /etc/modprobe.
c. Reboot
d. Set the mode to "Analog Surround 5.1 output" in the sound settings panel
--> Can you fix it in order to make it work more easily for users ?

@sami, Thanks for your comment.
I believe if you do this:
echo 0x16 0x99130111 > /sys/class/
echo 0x1e 0x99130112 > /sys/class/
...and then reconfig etc, you wouldn't have to do the asus-mode4 tweak as well. The thing is that the kernel driver isn't handling 2.1 very well (I just asked: http://
Is the above working for you as well?

@David
Indeed, your trick gave me exatly the same result.
Whatever trick I use (your post #49 or my post #48), there are still some limitations:
- When I boot the computer, I have to set the mode to "Analog Stereo Output" first and then back to "Analog Surround 5.1 output" to make the sound work (in the sound settings panel).
- When I put the omputer in sleep mode, there is no way to get sound working on resume
- When I play with the "output volume" in the sound settings panel, it sometimes make the sound become completely crushed (noisy, high pitch peaks). It may become "normal" again if I continue playing...
Let me know how to further investigate !

I can second that Sami, got that weird quirk here as well. I think it has something to do with the pulseaudio remixing for the subwoofer, but no exact idea.

I again altered some stuff: I prefer to use the hardware master channel to control volume instead of the PCM (software, meh) channel. Maybe the strange crackling stuff is over now as well as I'm not altering the PCM level anymore :)
I changed /usr/share/
[Element Master]
switch = mute
volume = merge
[Element PCM]
switch = mute
volume = ignore
override-map.1 = all
override-map.2 = all-left,all-right
[Element LFE]
switch = mute
volume = ignore
I think this file overrides the earlier modifications in /usr/share/
It works fine now anyway :D

does the sonicmaster subwoofer has a TRS connector(stereo) or TS connector (mono)?
do the subwoofer use both channel (left+right) ?

Rene Arts (renearts) wrote : | #56 |
My pulseaudio mixes the left and right channel to a (I suppose) mono channel and then sends it to the sub. Although the subwoofer connector features 4 contacts (TRRS connector). I think for presence detection or dummy load. I unscrewed the plastic barrel and found two wires wired to the voice coil and the two others are connected with a resistor.

I just tested it: I can hear sound coming from the subwoofer only with 'front right'. I suppose it's connected as a mono device. WIth the test above I think the pulseaudio mixing is bypassed? When I use another program (say Audacity) and then cut away the left, resp. right channel the sub works with both channels as it should.

As far as I can see it uses (L+R) and then only sends it to the right rear channel, so effectively using only half of the signal (making it (L+R)/2) which should result in the correct level. Here's the log I think you asked for: http://

Rene Arts (renearts) wrote : | #62 |
I don't know it for sure, but with the previous tests I heard no sound coming from the sub with the rear left test signal, but did with the rear right. The sub connector has 4 wires: 2 connected to the sub's voice coil and the two others to a resistor (I think dummy load, could be used for dectection of sub presence on the left channel). Ah wait... while writing the previous sentence the next idea rose: both channels might be (able to be) used. But because the left channel is hooked up to a resistor it off course cannot be heard. So still (L+R) might be used...
I did the tests you asked for anyway, the log is over here: http://

if this proprietary subwoofer is supported by asus laptop which use alc663 , just ignore the misc no_presence bit of pin default ane enable the unsolicited event with special event tag on pin 0x1e. define a customised alc_!633_

Hello,
On Ubuntu 13.10 (fresh install not upgrade) I observed that subwoofer yielded no sound.
So I tested two fixes separately, changes from vanilla configuration are indicated with "-->".
1. Post #8: Setting the pin configuration default to 0x99130112 for pin 0x16
--> Subwoofer plays sound, high frequencies included
--> Muting right channel at source mutes subwoofer, muting left channel at source does not affect subwoofer
--> alsamixer shows a "bass" volume control that affects subwoofer
--> alsamixer master volume affects all channels as expected
--> interference noise in subwoofer, not very loud but clearly audible when ear close to subwoofer
2. Post #34:
edit /etc/modprobe.
options snd-hda-intel model=asus-mode4
--> Same consequences (not tested volume details though)
Interference noise in subwoofer only happens when enabling one of those fixes.
Disappears immediately when doing rmmod snd-hda-intel.
Close attention to this noise, revealed that some noise remains even after rmmod snd-hda-intel, but it's more subtle because more or less the same power as the PC fan noise. As expected, unplugging the subwoofer from the jack removes that noise.
Keeping in mind the usual "hey it's open source, it's done when someone does it philosophy, why is this bug/feature not addressed ?
Because wiring is non-standard ?
Because it's difficult to implement an auto-detect + jack sense feature that just works ?
Because no one really cares (IMHO sound is not that good anyway, any decent external stereo will do much better, so I consider myself in the "not really cares" option) ?
Just my two cents.

it is not hard to implement jack detect
the main problem is no application including pulseaudio can receive stereo and output a four channels (with subwoofer at rear right) output which fit the hardware
pulseaudio can mix stereo but there is no low pass filter

(in reponse t o#76)
Raymond, the subwoofer signal is not a different output-bus on this laptop, it's something built into the sound card. There's no need to 'jack detect'. I have this laptop and applied the fix mentioned above. Still, my mixer only shows a stereo output (and the subwoofer works).
The hardware is connected via a proietary jack, not a 1/8" or RCA jack.
What I believe the problem is, is that ALSA does not assign the right "model" according to the firmware ID on this laptop, or some other mumbo-jumbo that I am not familiar with.

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" with the subwoofer plugged and unplugged and see if you get any difference.
