See Documentation/sound/alsa/HD-Audio.txt in the recent linux tree, or
   ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/docs/HD-Audio.pdf

The installation step for the snapshot tarball is identical with the
released version.  If you installed already alsa-driver tarball, do it
just in the same way.

If you haven't done it yet, just do the following four steps:

	% ./configure --with-debug=full --enable-dynamic-minors
	% make
	% su
	# make install-modules
