CHECK THE SPEAKER CABLE CONNECTIONS — Ensure that the speakers 
are connected as shown on the setup diagram supplied with the speakers.
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.

and Audio Devices. 
2 Click Sounds and Audio Devices.
3 Click the Hardware tab.
