IMiniportAudioEngineNode interface (portcls.h)
This interface allows a miniport driver to use KS properties that access the audio engine via a KS filter handle.
Inheritance
The IMiniportAudioEngineNode interface inherits from the IUnknown interface. IMiniportAudioEngineNode also has these types of members:
