ENSURE THAT THE SUBWOOFER AND THE SPEAKERS ARE TURNED ON — See the
setup diagram supplied with the speakers. If your speakers have volume controls,
adjust the volume, bass, or treble to eliminate distortion.
ADJUST THE WINDOWS VOLUME CONTROL — Click or double-click the speaker
icon in the lower-right corner of your screen. Ensure that the volume is turned up
and that the sound is not muted.
DISCONNECT HEADPHONES FROM THE HEADPHONE CONNECTOR — Sound from
the speakers is automatically disabled when headphones are connected to the
computer’s front-panel headphone connector.
TEST THE ELECTRICAL OUTLET — Ensure that the electrical outlet is working by
testing it with another device, such as a lamp.
ELIMINATE POSSIBLE INTERFERENCE — Turn off nearby fans, fluorescent lights,
or halogen lamps to check for interference.
REINSTALL THE SOUND DRIVER — See "Manually Reinstalling Drivers" on
page 90.
RUN THE HARDWARE TROUBLESHOOTER — See "Restoring Your Operating
System" on page 91.
CHECK THE HEADPHONE CABLE CONNECTION — Ensure that the headphone
cable is securely inserted into the headphone connector (see "Front View of the
Computer" on page 15).
ADJUST THE WINDOWS VOLUME CONTROL — Click or double-click the speaker
icon in the lower-right corner of your screen. Ensure that the volume is turned up
and that the sound is not muted.
