No Sound

Using WDM drivers (itunes likes these over purewave) / AA 2.0 / 44.132 - no sound. When I use purewave drivers I have sound.

And now we have to guess what question belongs to this anwer? 

I mean, you do have sound with the Purewave drivers (where the WDM offer basic functionality only), so what's the problem? Try the Asio4All drivers for AA, and the WDM drivers for other sound applications, I would say.
