Gets the collection of audio devices.
Assembly: Microsoft.Lync.Model (in Microsoft.Lync.Model.dll)
All audio devices that have both a microphone and speaker are returned. For example, a UC-enabled headset such as a headset with microphone is returned. Audio devices that have only one of these two components are not returned. A virtual audio device that is defined in the Lync Audio Device Setting option page is also returned as long as it is defined with a physical speaker and a physical microphone.
