Using the sound control buttons on your computer
There are two sets of buttons on the front of your Macintosh. The set on the right (marked with the - icon) is for sound control. You can use these buttons to increase or decrease the volume of the sound your Macintosh plays:
mPress the button on the right to make the sound louder.
mPress the button on the left to make the sound softer.
You can also adjust the sound by using the Monitors & Sound control panel, in the Control Panels folder in the Apple (K) menu. Your computer also comes with “surround sound” technology, which is enabled in the Monitors &
Sound control panel. The 
3D Surround Sound technology broadens the sound you hear through your monitor’s speakers. 3D Surround Sound makes the speakers sound as if they are set wider apart, and you can hear many “points” of sound. (3D Surround Sound does not work through the headphone jack on the front of the computer.)

Macintosh Guide, available in the Guide (h) menu.
