What to do if my auna AMP-4000 DAB Amplifier display lights up but there is no sound?

If the display of your auna Amplifier lights up but there's no sound, the issue might be due to loose speaker connections. Ensure they are securely connected. Alternatively, the volume control might be set to the minimum level. Try turning the volume up.
