Hi I recently bought a used 2014 Audi A4 s line and for some reason when I start the car there is no sound yet the mmi shows its playing with the volume working but it wont output sound until I go into the boot and unplug what I think is the most cable and plug it back in and it works until I switch the car off then I have to repeat again. I've gave it a scan with vcds and can't seem to find anything that would be causing it and I've ran output tests which show the speakers and amp working no problem so I'm guessing the mmi can't be initialising the speakers automatically on boot for some reason so maybe some coding can help? Any help appreciated thanks
