CHECK/FIX AUDIO PLAYBACK
Grab some earbuds. In many cases the problem lies with the physical connections beyond our system, or with the amplifier, while music is in fact playing on the music player. To confirm that music is not playing, remove the audio cable and insert the earbuds we shipped with your system, or use your own. Plug the earbuds into the audio jack and listen.
Plug into the correct jack. Hearing static or nothing at all? Make sure the audio cable is plugged into the correct jack. It's small and round and frequently labeled A/V.
Check the volume setting on your amplifier.
