IMMNotificationClient Interface
Provides notifications when an audio endpoint device is added or removed,
when the state or properties of an endpoint device change,
or when there is a change in the default role assigned to an endpoint device.
Unlike the other interfaces in this section, which are implemented by the MMDevice API system component,
an MMDevice API client implements the
IMMNotificationClient interface.
To receive notifications, the client passes a pointer to its
IMMNotificationClient interface instance as a
parameter to the
RegisterEndpointNotificationCallback(IMMNotificationClient) method.
