I have Asus n56dp with amd processor and graphics not intel. I can't get the subwoofer working.
lspci | grep Audio output:
00:01.1 Audio device: Advanced Micro Devices [AMD] nee ATI Device 9902
00:14.2 Audio device: Advanced Micro Devices [AMD] Hudson Azalia Controller (rev 01)

I too have an Asus N56DP. We two may be the only guys running ubuntu on them right now. :)
The following sort of works:
in your /etc/rc.local add this:
echo 0x1e 0x99130112 > /sys/class/sound/hwC0D0/user_pin_configs echo 1 > /sys/class/sound/hwC0D0/reconfig
then reboot.
Then in your sound control panel (System Settings -> Sound) select output-> either analog if you just want it to work, or if you want proper bass you have to keep switching between surround 4.1 and 5.1 all the time. For instance mplayer will often turn off the bass and I'll have to switch from one to the other.
I chose analog.
