for now best i have acheived is:

with this option you wont have to change profiles each time song

correct me if im wrong but that commit will just automatically set 'asus-mode4'

and that for sure does not make the woffer play what it should - it plays all
the tones right now - not just the 'basses'.
playing with pulseaudio config helps nothing - it is playing what it is liking.

Title:
[N56VZ, Realtek ALC
so what is missing?
can someone with such knowledge write summary like alsa is missing this and
this or pulse is missing this or this
also if its possible to code it without nasty hacks that wont be merged into
mainline - i can code but i dont know alsa nor pulseaudio code structure - too
much
echo 1 > /sys/class/sound/hwC0D0/reconfig
the side effect of dynamic reconfigure is the driver remove the controls
(1 to 24) except those user space softvol controls (25 to 26), create
the new controls from 27
Alsactl output

Correction to my previous post. I HAVE to switch from 4.1 to 5.1 or 5.1
to 4.1 on reboot to make the change take effect. Either 5.1 or 4.1 work
after that.

Just and FYI that this bug also affects the N56DP (AMD version of the
N56) and the #1 fix in the first post does fix the problem for me as
long as I use surround 4.1 as 5.1 does not work.

can you post the pulseaudio verbose log for surround41 ?
pactl set-card-profile 0 output:analog-surround-41+input:analog-stereo
since pulseaudio server disable channels conversion and HDA does not
support 1, 3 , 5 or 7 channels

hi folks, I own too a N56VZ and I am affected by the lack of support for
subwoofer under linux
I've been able to make it work with the workaround #2
echo 0x16 0x99130111 > /sys/class/sound/hwC0D0/user_pin_configs
echo 0x1e 0x99130112 > /sys/class/sound/hwC0D0/user_pin_configs
echo 1 > /sys/class/
the deskstop users are suffered from the side effect of copy front since
stereo is copied to all speakers
can alsa only enabled this feature for notebook ?

for (i = 1; i < mout->num_dacs; i++) {
if (chs >= (i + 1) * 2) /* independent out */
not sure why the subwoofer use TRRS Jack
does it use spdif since 3 pins

i think it is best that can be achieved now, ive saw few people saying that it
is working good on their notebook(various asus notebooks like n46vz etc), but
when i asked them via pm if it is really working like it should - i mean
symptoms like sami mentioned in post #32, etc. they said it is ex
Whoo... Nothing understandable for me ))) I have asus n56vz, all I have done
leads me to the subwoofer playing rear right only. No lo-pass filters - so it`s
not usable...
I am not so good in English and all that pins to understand - is there any
working solution or not?
I have asus-mode4 fix an
hello, i have asus n76vz (its the same as n56vz but it have 17 inch
screen) and i can report that the best i can get is exactly same
behavior as "sami" mentioned in post #32

does the enter playback volume has and effect on the suboofer ?
there are only three DAC with volume control , the headphone will have
to share the volume control in 5.1
the reason why you change the spdif out to speaker is just a hack to
trick the driver to config 5.1 with the headphone playback
In Analog Surround 5.1 output with the previous version of pulse that allows
the subwoofer to work :
- LFE is affecting only the subwoofer volume
- Center has no effect
- Front affects both left and right speakers, but not the subwoofer except if
you balance left or right
--> This seems to me a n
Hi Raymond,
I am not an expert, but even under Windows there is no light within the
spdif output jack.
The spdif output jack is mutualized with the 3.5 earphone jack.
So I think the spdif output is a copper one, not optical... (I don't know how
to check this)

a. Add to rc.local :

b. Add options snd-hda-intel model=asus-mode4
Hi,
I downgraded pulseaudio : sudo apt-get install pulseaudio=1:1.1-0ubuntu15
It's working again.
So it has to do with the las upgrade of pulse audio (1:1.1-0ubuntu15.2)...
Anyway, I also noticed that there are changes in Pin names (i don't know when
it changed, but it differs from my initial po
forget about changes in pin names : this is due to the PIN
reconfiguration...
