How do I fix the sound issue in my Audi A4?

I've noticed that my Audi A4's sound system is not producing the same high-quality sound it used to. It sounds distorted and uneven. What could be causing this and how can I fix it?

It's possible that there is a problem with the speakers or the wiring in your A4. You can try checking the connections and replacing any faulty components.

Another potential cause could be a software issue. Make sure your Audi's software is up to date and consider resetting it if necessary.

If neither of those solutions work, it's best to take your car to a professional mechanic or Audi dealership for further diagnosis and repair.
