No sound from headphones
CHECK THE SPEAKER CABLE CONNECTIONS — Ensure that the speakers are connected as shown on
the setup diagram supplied with the speakers. If you purchased a sound card, ensure that the speakers
are connected to the card.
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.
