With a lot of AC97 controllers the hardware won't allow you direct
access to the cooked wire data, you'll only be able to see decoded audio
streams.  What is it that you're actually trying to do?

For embedded platforms you mostly want to look under sound/soc though
there are a few platforms outside of there.
