Try re-setting your high scores and see if that dosen't make him say what you want.

Go into the adjustments and credits thru the coin door (middle button up position) and (number audits 10) reset game audits press start button to yes. That should clean all scores and credits to give you that sound at the end of the game. I just cleared off all that information and it worked on my machine. You will have to open the expand adjustments to get there.

I'm sorry adjustment 10 not audit 10.
