If a client computer has more than one webcam and microphone, you can configure a preferred webcam and default microphone that Real-Time Audio-Video will redirect to the desktop. These devices can be built in or connected to the local client computer.

On a Windows client computer that has Horizon Client for Windows 4.2 or later installed, you can select a preferred webcam or microphone by configuring Real-Time Audio-Video settings in the Horizon Client Settings dialog box. With earlier Horizon Client versions, you modify registry settings to select a preferred webcam and use the Sound control in the Windows operating system to select a default microphone.

On a Mac client computer, you can specify a preferred webcam or microphone by using the Mac defaults system.

On a Linux client computer, you can specify a preferred webcam by editing a configuration file. To select a default microphone, you can configure the Sound control in the Linux operating system on the client computer.

Real-Time Audio-Video redirects the preferred webcam if it is available. If not, Real-Time Audio-Video uses the first webcam that is provided by system enumeration.
