The AC'97 PRM is here:
http://download.intel.com/design/chipsets/manuals/30701701.pdf
The Intel HD Audio PRM is here:

Both are specs for onboard codec buses.  More recent chipsets utilize
the HD Audio bus specification, as it gives superior output capabilities
and supports more devices (like modems and other vendor defined codecs).
One of the main improvements over the AC'97 spec is the uniform
programming interface (which is one of the problems you seem to be
running into).

Beyond that, others will need to interject more answers to your
questions.
