Represents an audio device connected to a local computer.
Assembly: Microsoft.Lync.Model (in Microsoft.Lync.Model.dll)
The Device.IsActive property returns true when the audio device will be used in the next conversation that is started. In addition, setting this property to true while a call is active causes this audio device to be used during the active call. After the call ends, the original audio device is used for future calls. In order to be sure the desired audio device is used for future calls, you must set the IsActive property to true when no calls are active.
