IAudioStreamVolume class com

The IAudioStreamVolume interface enables a client to control and monitor the volume levels for all of the channels in an audio stream. The client obtains a reference to the IAudioStreamVolume interface on a stream object by calling the IAudioClient::GetService method with parameter riid set to REFIID IID_IAudioStreamVolume.
