Audi A3 displaying 'Sound Unavailable' may be because it was muted when the car was last turned off, so the vehicle still remembers the mute status upon restart. Simply restarting the car should resolve the issue. Reasons why the Audi A3's audio system has no sound: Mute status: If the Audi A3 has no sound, first locate the volume control knob on the vehicle's center console. Turn the knob to the right to adjust it to the maximum volume. Then press and hold the voice control button on the right side of the multifunction steering wheel for five seconds. Turn off the engine, then press the button again and start the engine. The mute status should now be restored. CD power supply issue: First, check the CD player's power supply and determine if it's damaged based on the indicator light. The CD player compartment should open and close normally. If there's no power, check the power supply, including the fuse box and wiring. If there is power, consider whether the audio system has been modified. If it has, check the modified fuse. If not, check if the audio output cable has come loose. Generally, it's unlikely that all speakers would fail simultaneously. Audi A3 configuration introduction: The Audi A3 is equipped with a parking assistance system and a panoramic sunroof but lacks navigation, DVD, and a rearview camera.
