ISubunit interface

The ISubunit interface represents a hardware subunit (for example, a volume control) that lies in the data path between a client and an audio endpoint device. The client obtains a reference to an ISubunit interface by calling the IDeviceTopology::GetSubunit method, or by calling the IPart::QueryInterface method with parameter iid set to REFIID IID_ISubunit.

Members

The ISubunit interface inherits from the IUnknown interface but does not have additional members.

For more information about ISubunit, see IPart Interface.
