Remarks
Support for the KSPROPERTY_AUDIOMODULE_COMMAND property allows Audio Module clients to send custom commands to query and set parameters on Audio Modules. The property can be sent through the filter or pin handle and a KSAUDIOMODULE_PROPERTY is passed as the input buffer for the DeviceIoControl call. A client can optionally send additional information immediately adjacent to the KSAUDIOMODULE_PROPERTY in the input buffer to send custom commands.
