Returns the AudioCaptureDevice object that represent the default audio capture devices on the client system.
Assembly: System.Windows (in System.Windows.dll)
Return ValueType: System.Windows.Media.AudioCaptureDevice
The AudioCaptureDevice object that represent the default audio capture devices on the client system.
On Mac OSX, if an application calls or GetDefaultVideoCaptureDevice and the default audio and video devices have not previously been set by the user, Silverlight will return the first device found. If a physical device is not connected to this CaptureDevice, an InvalidOperationException will be thrown when Start is called. This expectation should be caught by the application and the user can then be notified to manually set their default devices in the "Webcam/Mic" section of the Configuration Settings dialog.
For a list of the operating systems and browsers that are supported by Silverlight, see Supported Operating Systems and Browsers.
