This kind of sounds like WASAPI supports only onboard chipsets (right?). Does WASAPI support interfaces that reside outside the computer (like the RME BabyFace)? Does the connection type play a significant part?
I'm not an expert about this, so the following may or may not be true...but I think that the SONAR WASAPI mode is for internal chipsets only. I tried using it with external audio interfaces, and the results were about the same as MME.
