well the OEM chip is still a mystery but a clever engineer could use the audio signal as a trigger to play from a sound chip a few chosen sounds.

I have thought about this in the past. If you could always find out what state the machine was in, you could have your own hardware sound engine that would drive the speakers.

On the machines that I customize it does have a jackpot light and if you monitored when that light when on, you could then have it start playing "jackpot music" and then it would end when it went off because the bonus round would be over.
