You add them to your modprobe command line, like so:
modprobe snd-hda-intel model=5stack
There is a list of supported models in
Documentation/sound/alsa/ALSA-Configuration.txt in the linux source
distribution. I found an online copy at
http://www.mjmwired.net/kernel/Documentation/sound/alsa/ALSA-Configuration.txt
If you can get it working with one of these options, you can set up the
defaults options in one of the files in /etc/modprobe.d/ (alsa-base, I
think, but I'm not sure).
