How can I reset the audio settings on my Audi A4?

I accidentally changed some of the audio settings on my Audi A4 and now the sound quality is not as good. Can someone guide me on how to reset the settings to default?

To reset your audio settings, go to the car's settings menu and select 'Audio'. Then, choose the 'Restore factory settings' option. This will reset all audio settings to default.

You can try pressing and holding the MENU button on your MMI controller for 10 seconds to perform a hard reset of the audio system. This should reset all settings back to default.

If the above methods don't work, you can disconnect the car's battery for a few minutes and then reconnect it. This will also reset all settings including the audio.
