ITAudioDeviceControl interface
[ This interface is not available for use in Windows Vista, Windows Server 2008, and subsequent versions of the operating system. The RTC Client API provides similar functionality.]
The ITAudioDeviceControl interface exposes methods that enable an application to get and set parameters for control of an audio device.
This interface is implemented by the IPConf MSP and the H323 MSP. It is exposed when a call uses these service providers or a third party service provider that implements this interface. To obtain a pointer to the ITAudioDeviceControl interface, call QueryInterface on the ITStream interface that controls the audio device corresponding to the stream. The media type of the ITStream interface must be audio for the ITAudioDeviceControl interface to be exposed.
