for now best i have acheived is:
- pins configured as #2 solution says (first post in this bug report)
- in /etc/pulse/daemon.conf you need to enable this option:
enable-lfe-remixing = yes
with this option you wont have to change profiles each time song
changes to get woofer working
- use a 'daemon' from this bug report (post #41) or my little changed ver (it
shows 'ubuntus' notifications when plugged etc)
this setup 'tries' to play correctly when you provide 5.1 input - try with some
movie - credits have some music
the woofer tries to play only basses - the problem is that they are not clean
and loud - havent figured out why yet.
when you provide stereo input it plays left/right channel (all the tonnes)
theoretically this option: enable-remixing = yes in /etc/pulse/daemon.conf
should fix it (it should do 'low-pass' filter and the woofer should get only
basses)
but it doesnt work - setting custom channel-map / default-sample-channels helps
nothing
setting in /etc/pulse/default.pa
load-module module-alsa-sink device=hw:0 channels=6 channel_map=here many
different channel mappings(same num as channels num)
also helps nothing
normally when set 5.1 profile - the woffer loudness is affected also by
front-left/right volume (the volume sliders in pavucontrol)
but when you add to the /etc/pulse/default.pa this line:
load-module module-combine channels=3 channel_map=front-left,front-right,lfe
you will see in pavucontrol another set of sliders left right woffer
put these 5.1 sliders to the eg. 50 / 100%
play some music (can be stereo) doesnt matter, in pavucontrol (playback tab)
set your music app so it will play to the 'simultaneous output to built-in
audio analog surround 5.1'
go to output devices tab and now front-left / right doesnt change the volume of
the woffer - can mute both and the woffer will just play (you need to use these
new added set of sliders (these 3)) - not the default 5.1 sliders
prolly its not 'ready' / nice to use but its good for testing - you can hear
what your woffer really is playing etc.
if someone wants this option - you can add it to the 'daemon' script - so it
will load / unload that module when you plug/unplug the speaker (using pacmd or
smth.)
also be sure to restart pulse every time you change its config files:
pulseaudio --kill should do the job (it should autospawn after few secs) if
not just use pulseaudio --start (do these as nonroot user)
whats left is to force pulseaudio to 'create the basses' on the fly (lowpass
filter) - maybe then it wont play left/right channel
if someone has any idea how to improve it - feel free i can test

Title:
[N56VZ, Realtek ALC663, Black Headphone Out, Right] No sound at all:
Subwoofer not working
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
Hi,
this bug is a fork of https://bugs.launchpad.net/ubuntu/+source/alsa-
driver/+bug/871808 because #871808 stands for a different hardware
with a different solution, so people may get confused.
Here is a summary (see post #48 to #54 of #871808):
The subwoofer of Asus N56VZ laptop doesn't work "out of the box".
#sudo hda-jack-sense-test -a :
*** Without subwoofer:
Pin 0x1e (Black SPDIF Out): present = No
*** With subwoofer:
Pin 0x1e (Black SPDIF Out): present = Yes
http://www.alsa-
project.org/db/?f=2778e7f430aa95ae219d0b2bc3cb5e46abd0a33a
--> There are two ways of making it work:
#1
a. Add to rc.local :
echo 0x1e 0x99130112 > /sys/class/sound/hwC0D0/user_pin_configs
echo 1 > /sys/class/sound/hwC0D0/reconfig
b. Add options snd-hda-intel model=asus-mode4 in
/etc/modprobe.d/alsa-base.conf
c. Reboot
d. Set the mode to "Analog Stereo Output" and then to "Analog Surround 5.1
output" in the sound settings panel. You have to do this each time you reboot!!!
#2
a. Add to rc.local :
echo 0x16 0x99130111 > /sys/class/sound/hwC0D0/user_pin_configs
echo 0x1e 0x99130112 > /sys/class/sound/hwC0D0/user_pin_configs
echo 1 > /sys/class/sound/hwC0D0/reconfig
b. Reboot
c. Set the mode to "Analog Stereo Output" and then to "Analog Surround 5.1
output" in the sound settings panel. You have to do this each time you reboot!!!
Both give the same results and fix the bug.
--> Can you make it work out of the box?
There is still two other bugs on this laptop :
- crackling audio when playing with sound volume: see
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1040867
- When I put the omputer in sleep mode, there is no way to get sound working
on resume: should I open a new bug to investigate this?
Regards
Sam
