Select a Preferred Webcam or Microphone on a Linux Client System
With the Real-Time Audio-Video feature, if you have multiple webcams and microphones on your client
system, only one webcam and one microphone can be used on your Horizon 7 desktop. To specify which
webcam and microphone are preferred, you can edit a conguration le.
The preferred webcam or microphone is used on the remote desktop if it is available, and if not, another
webcam or microphone is used.
With the Real-Time Audio-Video feature, webcams, audio input devices, and audio output devices work
without requiring the use of USB redirection, and the amount network bandwidth required is greatly
reduced. Analog audio input devices are also supported.
To set the properties in the /etc/vmware/config le and specify a preferred device, you must determine the
values of certain elds. You can search the log le for the values of these elds.
n
For webcams, you set the rtav.srcWCamId property to the value of the UserId eld for the webcam and
the rtav.srcWCamName property to the value of the Name eld for the webcam.
The rtav.srcWCamName property has a higher priority than the rtav.srcWCamId property. Both properties
should specify the same webcam. If the properties specify dierent webcams, the webcam specied by
rtav.srcWCamName is used, if it exists. If it does not exist, the webcam specied by rtav.srcWCamId is
used. If both webcams are not found, the default webcam is used.
n
For audio devices, you set the rtav.srcAudioInId property to the value of the Pulse Audio
device.description eld.
