supplied with the speakers. If your speakers have volume controls, adjust the volume, bass, or treble to
eliminate distortion.

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.
