Sorry to drag this one up again but it is doing my head in. I posted a while ago that when you launch a ball and it drops in the swamp from the shooter I don't get the sound quotes. While playing the other night they suddenly worked, game after game. Turned it on next day and nothing again since. I now know the roms are good but what else can it be? Every other sound is working as it should, I get the bong when I turn it on so I assume the sound board checks out, all swamp switches work as they should so what could it be?
