Audio is available for Professional and Enterprise users and allows the user to play audio on the Server and hear it on the Viewer. Now, in addition to seeing what is displayed on the Viewer and controlling the remote computer as though you were sitting in front of it, you can also hear what is playing on its speakers.

The audio feature will only work when you’re using High-Speed-Streaming (RFB protocol version 6). If you are using direct connectivity via a router then you may need to add the appropriate port forwarding rules to allow UDP connections as well as TCP. On Linux systems, the pulse audio sound system must be installed in order to use the remote audio feature. This should be present by default on most recent Ubuntu, RHEL and CentOS systems. Make sure you have the updated version of the Server and Viewer installed, and a Professional or Enterprise subscription, and you should be good to go.
