You shouldn't need to implement PROPOSEDATAFORMAT.

My VAD is a bit "oldish", based on an earlier WDK, so I haven't implemented any handler for KSPROPERTY_PIN_PROPOSEDATAFORMAT. So I did this, but it fails directly at row 909 (reference C:\WinDDK\7600.16385.0\src\audio\msvad\simple\minwave.cpp). Ideas ?
