Title:
  [N56VZ, Realtek ALC663, Black Headphone Out, Right] No sound at all:
  Subwoofer not working

Status in alsa-driver package in Ubuntu:
  Triaged

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?
