Assembly: Microsoft.Office.Interop.UccApi (in microsoft.office.interop.uccapi.dll)
The event is used to notify an application of a change in the volume or intensity level of an audio. This is a dispinterface. Its members define the event handlers for the events raised by an IUccAudioMediaChannel object. To catch the events, a UCC API client must implement these event handlers and advise the event source of the implementation if it is interested in receiving the events. To prevent memory leaks, the client should unadvise the events when it is no longer interested in the events.
