A year ago, Daniel Germann reported on this list that his WaveCyclic driver was triggering a crash very early in sysaudio.sys!AddPinToFilterNode. My TV audio/video capture filter is triggering the same crash at the same point in sysaudio.sys!AddPinToGraphNode. If Daniel is still watching, what was the resolution of your problem?

The problem starts when I add KSCATEGORY_AUDIO to my filter category list. If I omit that, I can force an audio graph together in graphedt and it works fine, but the audio doesn't render by default.
