Which Devices Are Selected from My Client?

You may have multiple audio and video devices available on your client machine. If the video or audio does not come from your expected source device, then you may need to select a specific source device for use.

We believe that all webcams should be supported – however, we have of course not been able to test with every single webcam ever produced, so it is possible that we don’t support some. Do let us know if you find a device that does not work.

We also suspect (but have not tested) that other video source devices may work too. For example, TV tuners?! [We would love to hear about any fun use cases you identify with non-webcam devices!]

In terms of audio devices, any type of audio input device supported by Windows should work. Whether these be analog-in using the older 3.5mm jack plugs, or digital devices such as USB headsets, they should all be usable.

Audio

It is expected that you will have multiple audio input options (e.g., built-in microphone, external USB headset, possibly analog audio-in, and even microphones built into a webcam!). Usually things should just work, but you may want to configure the system to select audio from a specific audio input device.

By default, RTAV will use the “default” audio-in device as specified in Windows Recording Sound Properties.

To select a different source audio device for RTAV:

  1. End your current RTAV session if one is active (by stopping a call in the 3rd-party app).
  2. On the client machine, right-click on the speaker icon in Notification Area Icons and select “Recording Devices” (or via Control Panel –> Sound).
  3. Right-click on the device you want to use, and select “Set as Default Device”
  4. Now start a new call in the guest, and the new audio-in device should be used. (No need for any Windows restarts!).

If you do not want to change your default client-side settings, it is also possible to configure the View Client to select a specific audio device if it is available. This is termed a “preferred” audio device. If the preferred audio device is not available, then the Windows default device would be used instead.
