Remarks
Support for the KSPROPERTY_AUDIOMODULE_NOTIFICATION_DEVICE_ID is required to enable the miniport to signal notifications and pass information to Audio Module clients. The lifetime of this ID is tied to the lifetime of the audio device being exposed and active to the Windows Audio stack. The property can be sent through the filter or pin handle and a KSPROPERTY is passed as the input buffer for the DeviceIoControl call.
For an example of using this KSPROPERTY see the SYSVAD audio driver sample.
