Go look at the MAME entries for that boardset. You'll see a listing for sound chips. Locate those and you'll know where you are.

The first thing I'd do if it were mine would be to verify the +12v to the sound amp chip then check for broken caps or volume control pots.

If you have an oscilloscope or audio probe you could make short work out of troubleshooting it.
