ISimpleAudioVolume class com Interface

The ISimpleAudioVolume interface enables a client to control the master volume level of an audio session. The IAudioClient::Initialize method initializes a stream object and assigns the stream to an audio session. The client obtains a reference to the ISimpleAudioVolume interface on a stream object by calling the IAudioClient::GetService method with parameter riid set to REFIID IID_ISimpleAudioVolume.
