Speakers

There is no sound from the speakers (external):

Ensure that 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 headphone connector.

Test the electrical outlet:

Ensure that the electrical outlet is working by testing it with another device, such as a lamp.

Reinstall the audio driver

Run the Vista or PSA Diagnostics

NOTE: The volume control in some MP3 players overrides the Windows volume setting. If you have been listening to MP3 songs, ensure that you did not turn the player volume down or off.
