The subwoofer balance control (
Ï
) on the back of your computer is not affecting
the volume.
The subwoofer balance control affects the subwoofer volume only when the
computer has external speakers attached or the monitor has built-in speakers.
Otherwise, the subwoofer balance control (Ï) has no effect on your
computer’s overall volume. Adjust your computer’s volume with the sound
controls on the front of the computer or monitor, with the volume control
sliders in the Monitors & Sound control panel (in the Apple [K] menu), or
with the volume controls in AppleCD Audio Player (if you’re listening to an
audio CD).
