Setting Computer Audio Volume You may want to standardize or otherwise configure the output volume of your computers. You could use this to silence a lab of computers all playing music, or turn up the volume on a single remote computer for a user's benefit. You can also set the alert volume separately from the output volume and input volume. Additionally you can set "output muted." Muting the volume causes the computer to remember what the previous volume level was and return to it when the sound is enabled again. Setting computer audio volume requires the use of Apple Remote Desktop's Send UNIX Command feature, AppleScript, and the command-line tool osascript. See "UNIX Shell Commands" on page 155 for more information. See AppleScript's StandardAdditions dictionary for information about using this tool.
