UNIX sound controls

The sdtaudiocontroller allows you to control the sounds on your SUN workstation. While the controls are relatively rudimentary, so are the sound facilities in the IMAGE lab.

Starting the audio controller

  1. Open an xterm shell by clicking on the IMAGE menu and selecting "Local X Term Shell."

  2. At the command line, type the following command:

    sdtaudiocontrol &

  3. After a few moments, the sdtaudiocontroller window will open (see image right). You may close the xterm shell.

Using the audio controller

Volume
To control the volume for the built-in speaker, use the mouse to slide the volume bar up or down.

Balance
Since the SUN workstations use a single internal speaker, you do not need to use the Balance control.

Mute
If you don't want any sound to play, click the Mute box to turn off sound entirely.

Application Controls
Some applications feature additional sound controls. To turn such controls on, click the "View" menu and select "Application Controls."
