User manual

This procedure describes how to choose a microphone from the user interface of the client system.
Administrators can also congure a preferred microphone by using the Mac defaults system. See “Congure
a Preferred Webcam or Microphone on a Mac Client System,” on page 58.
I If you are using a USB microphone, do not connect it from the Connection > USB menu in
Horizon Client. To do so routes the device through USB redirection and the device cannot use the Real-Time
Audio-Video feature.
Prerequisites
n
Verify that you have a USB microphone or another type of microphone installed and operational on the
client system.
n
Verify that you are using the VMware Blast display protocol or the PCoIP display protocol for the
remote desktop.
Procedure
1 On the client system, select Apple menu > System Preferences and click Sound.
2 Open the Input pane of Sound preferences.
3 Select the microphone that you prefer to use.
The next time that you connect to a remote desktop and start a call, the desktop uses the default microphone
that you selected on the client system.
Configuring Real-Time Audio-Video on a Mac Client
You can congure Real-Time Audio-Video seings at the command line by using the Mac defaults system.
With the defaults system, you can read, write, and delete Mac user defaults by using Terminal
(/Applications/Utilities/Terminal.app).
Mac defaults belong to domains. Domains typically correspond to individual applications. The domain for
the Real-Time Audio-Video feature is com.vmware.rtav.
Syntax for Configuring Real-Time Audio-Video
You can use the following commands to congure the Real-Time Audio-Video feature.
