I use Ubuntu 12.04 on Asus N5 6VZ, the subwoofer used to work fine doing
the following trick advised by Sami:
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 Surround 5.1 output" in the sound
settings panel
But a few weeks ago, the "Analog Surround 5.1 output" box does not
appear anymore on the sound setting panel and the subwoofer is not
working. When plugged, I hear a small rumble from the subwoofer which is
normal and indicates me that iti is connected. But when I play music, no
sound is coming from it.
I tride to install this driver:
https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS But no result.
I also tride the second trick.
Here is my /etc/rc.local:
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
fstrim -v /
fstrim -v /home
echo 0x1e 0x99130112 > /sys/class/sound/hwC0D0/user_pin_configs
echo 1 > /sys/class/sound/hwC0D0/reconfig
exit 0
and my /etc/modprobe.d/alsa-base.conf:

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
