The PIC will have nothing whatsoever to do with the audio, it is far too slow to handle high quality digitized sound so it will only be used to drive indicators or maybe remote control if it has that feature.
However, PICs are very robust devices and it is unusual for them to break down. Before going further, are you sure that is where the problem lies? The pictures show one pin is not inserted into the socket properly so please check that isn't causing your fault.
