What to do if the Audi Q2L radio has no sound?

[AbelLee]

When the radio volume is turned to the minimum, the sound waves are beyond the range of human hearing, so no sound can be heard. Simply turn up the volume to hear the sound. Check if there is any abnormality with the antenna. It is likely that the radio head has aged, and replacing it will significantly improve signal reception. To hear the sound from the radio, it needs to be played through the speakers.
