Actually, it only has the skidding sound of the cars turning. No music, no motor sounds. I checked it on youtube and there should definitely be other sounds which I'm missing. Any ideas where to look first? I've changed the volume and that works to change the loudness of the skidding, but no other sounds. Ideas?
 
Ok, I think I may have found something. According to the schematics, there should be a chip in 8j/k that deals with audio. Can anyone with a Championship Sprint confirm that there should be a chip here?

Hmm only worked on one of these and it was the molex connector on the Audio board.
Check the actual Audio Board itself. I replaced all the caps, and reflowed on heat sink connections.
 
Received the chips in the mail today. I dreaded installing it fearing it wouldn't work and I'd be back at square one. I popped it in, fired it up, and got that cool whoop whoop sound! All sound works like a charm. Very happy it was just that.
