The webcam and audio device drivers must be installed, and the
webcam and audio device must be operable, on the client computer. To
support Real-Time Audio-Video, you do not have to install the device
drivers on the desktop operating system where View Agent is installed.

Ensuring That Real-Time Audio-Video Is Used Instead of USB Redirection
Real-Time Audio-Video supports webcam and audio input redirection for use in conferencing applications.
The USB redirection feature that can be installed with View Agent does not support webcam redirection. If
you redirect audio input devices through USB redirection, the audio stream does not synchronize properly
with video during Real-Time Audio-Video sessions, and you lose the benefit of reducing the demand on
network bandwidth. You can take steps to ensure that webcams and audio input devices are redirected to
your desktops through Real-Time Audio-Video, not USB redirection.
If your desktops are configured with USB redirection, end users can connect and display their locally
connected USB devices by selecting the Connect USB Device option in the Windows client menu bar or the
Desktop > USB menu in the Mac OS X client. Linux clients block USB redirection of audio and video
devices by default and do not provide the USB device options to end users.
If an end user selects a USB device from the Connect USB Device or Desktop > USB list, that device
becomes unusable for video or audio conferencing. For example, if a user makes a Skype call, the video
image might not appear or the audio stream might be degraded. If an end user selects a device during a
conferencing session, the webcam or audio redirection is disrupted.
To hide these devices from end users and prevent potential disruptions, you can configure USB redirection
group policy settings to disable the display of webcams and audio input devices in VMware Horizon Client.
In particular, you can create USB redirection filtering rules for View Agent and specify the audio-in and
video Device Family Names to be disabled. For information about setting group policies and specifying
filtering rules for USB redirection, see “Using Policies to Control USB Redirection,” on page 186.
CAUTION If you do not set up USB redirection filtering rules to disable the USB device families, inform your
end users that they cannot select webcam or audio devices from the Connect USB Device or Desktop > USB
list in the VMware Horizon Client menu bar.
Selecting Preferred Webcams and Microphones
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, you select a preferred webcam by setting a registry key value. On a Mac OS
X client computer, you can specify a preferred webcam or microphone by using the Mac OS X defaults
system. On a Linux client computer, you can specify a preferred webcam or microphone by editing a
configuration file. 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.
To select a default microphone, you can configure the Sound control in the Windows, Mac OS X, or Linux
operating system on the client computer.
