The 6-stack is an option passed to the hda-intel alsa driver. The 
hda-intel driver works with many different sound chipsets. On some 
(most?) of them it can automatically detect all features. Some require 
an option passed to the module. On my system I was able to use dmesg and 
a file from the kernel source to determine the correct option to pass. 
Look in /usr/src/<kernel 
version>/Documentation/sound/alsa/HD-Audio-Models.txt. Or at this link:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.31.y.git;a=blob_plain;f=Documentation/sound/alsa/HD-Audio-Models.txt;hb=HEAD
