What is the best way to troubleshoot an audio issue in an Audi A5?

I have been experiencing a strange buzzing noise coming from my audio system in my Audi A5. It seems to happen randomly and I'm not sure what the cause could be. Has anyone else experienced this issue and know how to fix it?

The first thing to try is resetting the audio system by disconnecting the battery for a few minutes. If that doesn't work, it could be a loose connection or faulty wiring.

There have been reports of a similar issue with faulty grounding in the A5's audio system. Take it to a mechanic or dealership to have it checked out.

Make sure your audio settings are properly configured and that all connections are clean and secure. Sometimes small issues like that can cause major sound problems.
