Remarks

Client user permission to access the captures from available devices is scoped by sites in domains, and must be enabled per session.

If multiple devices are available, the user can select the device to use as part of the Silverlight configuration dialog (Webcam/Mic tab). In configuration UI, audio devices and video devices are listed separately and each can have a default. If a device is unavailable in the configuration UI, no CaptureDevice instance represents it.

On some systems, audio devices are not reported unless a microphone is plugged in and enabled; the presence of a sound card but no plugged-in microphone for it does not appear as an audio capture device in the list.
