I went through something similar many years ago and found I had to include property handlers for KSPROPERTY_AUDIO_CHANNEL_CONFIG and KSPROPERTY_AUDIO_STEREO_SPEAKER_GEOMETRY in the miniport's DAC node (KSNODETYPE_DAC).

So WMP does the right thing, now I onlyneed to figure out how to make it do the right thing with my VAD...Ok, searching the archives I came across KSPROPERTY_PIN_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 (referenceC:\WinDDK\7600.16385.0\src\audio\msvad\simple\minwave.cpp). Ideas ?
