IChannelAudioVolume class com

The IChannelAudioVolume interface enables a client to control and monitor the volume levels for all of the channels in the audio session that the stream belongs to. This is the session that the client assigned the stream to during the call to the IAudioClient::Initialize method. The client obtains a reference to the IChannelAudioVolume interface on a stream object by calling the IAudioClient::GetService method with parameter riid set to REFIID IID_IChannelAudioVolume.
