Client audio settings

This option controls how the sound from the remote application or desktop is directed to the client machine.

Select 'Enable Audio' to disable client audio mapping. This does not affect the client to server audio data, which is controlled through the "Remoting client devices" policy.

The audio quality between client and server can be set from the Sound Quality drop-down menu. The available options are High, Low and Medium.

The lowest and highest port number ranges must be between - 16384 to 65535

Troubleshooting:
The server audio options take precedence over these settings, so selecting high quality from the client might not result in a high quality audio being used. The server cannot increase the quality of the audio selected by the client.
