With the Real-Time Audio-Video feature, if you have multiple webcams or microphones on your client system, only one of them is used on your remote desktop or application. To specify which webcam or microphone is preferred, you can configure Real-Time Audio-Video settings in Horizon Client.

The preferred webcam or microphone is used on the remote desktop or application if it is available, and if not, another webcam or microphone is used.

With the Real-Time Audio-Video feature, video devices, audio input devices, and audio output devices work without requiring the use of USB redirection, and the amount of network bandwidth required is greatly reduced. Analog audio input devices are also supported.

Note: If you are using a USB webcam or microphone, do not connect it from the Connect USB Device menu in Horizon Client. To do so routes the device through USB redirection, so that the device cannot use the Real-Time Audio-Video feature.


  • Verify that you have a USB webcam, or USB microphone or other type of microphone, installed and operational on your client system.
  • Verify that you are using the VMware Blast display protocol or the PCoIP display protocol for your remote desktop or application.
  • Connect to a server.


  1. Open the Settings dialog box and select Real-Time Audio-Video in the left pane.
    You can open the Settings dialog box by clicking the Settings (gear) icon in the upper right corner of the desktop and application screen, or by right-clicking a desktop or application icon and selecting Settings.
  2. Select the preferred webcam from the Preferred webcam drop-down menu and the preferred microphone from the Preferred microphone drop-down menu.
    The drop-down menus show the available webcams and microphones on the client system.
  3. Click OK or Apply to save your changes.


The next time you start a remote desktop or application, the preferred webcam and microphone that you selected are redirected to the remote desktop or application.
