The IAudioClock2 interface is used to get the current device position.
To get a reference to the IAudioClock2 interface, the application must call IAudioClock::QueryInterface to request the interface pointer from the stream object's IAudioClock interface.
The client obtains a reference to the IAudioClock interface of a stream object by calling the IAudioClient::GetService method with parameter riid set to REFIID IID_IAudioClock.
When releasing an IAudioClock2 interface instance, the client must call the interface's Release method from the same thread as the call to IAudioClient::GetService that created the object.
