I don't have a Realtek AC97 setup to test with myself, so are you 
willing to do some debugging?  What you'd need is Visual Studio and the 
code out of CVS.  You could start by compiling and running ALTest in 
openal/demos/altest -- that will allow you to test specific AL features 
in isolation, and I'd be fine with working with you via email once you 
get the debug environment set up...
