Why do you expect the driver optimized for 1792 also works flawlessly for 1796?
It may work by changing the .inf, but it may damage the SQ IMO..
the Windows WDM device drivers are not from Asus(they only did the ugly sluggish GUI), and the ST drivers work just fine on the STX and the D2X, and all the other Xonar cards....and I'd dare to say that the SQ has improved, if not identical.
it's like Sapphire(and the likes) repackaging the generic ATi drivers
Maybe I should whine to C-Media to get "automatic samplerate" after all, as this needs to be implemented in the WDM system drivers in the first place.
PS: damn I'm listening to the 32bit remastered BEST OF from Barry White, the STX really gives a mind blowing SQ(w/ 3x49720HA and the latest ST drivers)
