read also /usr/src/linux/Documentation/sound/alsa/HD-Audio.txt

There is also excelent ALSA documentation in their project page.

write also in feature how you are testing things (which programs) and
possibly supply log information.

i.e. 
        arecord -L 
and 
        aplay -L 
and
        amixer
output
