have been listening to MP3 songs, ensure that you did not turn the player volume down or off.
Check the speaker cable connections — Ensure that the speakers are connected as
shown on the setup diagram supplied with the speakers. If you purchased an audio 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.
