KSPROPERTY_AUDIOMODULE_DESCRIPTORS

KSPROPERTY_AUDIOMODULE_DESCRIPTORS is used to retrieves the static data descriptor for each audio module on the endpoint wave filter.

Get	Set	Target	Property descriptor type	Property value type
Yes	No	Filter or Pin	KSPROPERTY	For filter target, a KSMULTIPLE_ITEM followed by an array of KSAUDIOMODULE_DESCRIPTOR that describe the template modules. For pin target, a KSMULTIPLE_ITEM followed by an array of KSAUDIOMODULE_DESCRIPTOR for the instantiated modules in that stream path.

KSPROPERTY

For filter target, a KSMULTIPLE_ITEM followed by an array of KSAUDIOMODULE_DESCRIPTOR that describe the template modules.

For pin target, a KSMULTIPLE_ITEM followed by an array of KSAUDIOMODULE_DESCRIPTOR for the instantiated modules in that stream path.

The property value is a structure, followed by zero (0) or more KSAUDIOMODULE_DESCRIPTOR structures.

KSPROPERTY_AUDIOMODULE_DESCRIPTORS returns an array of these descriptors is returned in response to this request.

If the driver support this property but it doesn’t have any audio modules, it returns an ksmultiple_item with zero element count.
