How can I troubleshoot a malfunctioning radio in my Audi A2?

I can't seem to get any audio to play on my radio in my Audi A2. The display turns on, but no sound comes out. What steps can I take to diagnose and fix this issue?

First, check the audio settings on your radio to make sure they are not muted or turned down too low. If that doesn't work, try resetting the radio by disconnecting the battery and reconnecting it after a few minutes. If the issue persists, it may be a problem with the wiring or speakers and you may need to take it to a mechanic.
