IMMDevice Interface
Provides methods for enumerating multimedia device resources.
In the current implementation of the MMDevice API,
the only device resources that this interface can enumerate are audio endpoint devices.
A client obtains a reference to an
IMMDeviceEnumerator interface by calling the CoCreateInstance.
The device resources enumerated by the methods in the IMMDeviceEnumerator interface are represented as
collections of objects with
IMMDevice interfaces.
A collection has an IMMDeviceCollection interface.
The IMMDeviceEnumerator.EnumAudioEndpoints method creates a device collection.
