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.
ISubunit inherits from the IUnknown interface. The ISubunit interface supports only the methods that it inherits from IUnknown.
For more information about ISubunit, see IPart Interface.
