Citrix Systems 10 manual To turn client audio on or off on a server

32 Client for Macintosh Administrator’s Guide

Note: Client audio mapping is not available when you connect to computers running Presentation Server for UNIX.

Three different audio quality settings are available. The higher the audio quality, the more bandwidth is required to transfer the audio data. Higher quality audio also uses more server CPU to process.

You can set the audio quality or turn client audio mapping on or off on the server. You can set the audio quality or turn client audio mapping on or off for each connection file. If the client and server audio quality settings are different, the lower of the two qualities is used.

The audio quality options are:

•High. This setting is recommended only for connections where bandwidth is plentiful and sound quality is important. It allows clients to play a sound file at its native data rate. Sounds at the highest quality level require about 1.3 Mbps of bandwidth to play clearly. Transmitting this amount of data can result in increased CPU utilization and network congestion.

•Medium. This setting is recommended for most LAN-based connections. This setting causes any sounds sent to the client to be compressed to a maximum of 64 Kbps. This compression results in a moderate decrease in the quality of the sound played on the client. The host CPU utilization decreases compared with the uncompressed version because of the reduction in the amount of data being sent.

•Low. This setting is recommended for low-bandwidth connections, including most modem connections. This setting causes any sounds sent to the client to be compressed to a maximum of 16 Kbps. This compression results in a significant decrease in the quality of the sound. The CPU requirements and benefits of this setting are similar to those of the Medium setting; however, the lower data rate allows reasonable performance for a low-bandwidth connection.

To turn client audio on or off on a server

From the ICA Settings dialog box on the server, administrators can turn client audio on or off by choosing the appropriate option. See the Presentation Server documentation for details.

To turn audio mapping on for a specific connection

1.In the ICA Client Editor, open the connection file you want to edit.

2.From the Connection Properties tab, choose Enable Sound.

3.Set Quality to High, Medium, or Low, depending on available bandwidth.
