Actually, I have 2 Mat Mania PCBs, and both have the same problem. They play just fine, but have no sound. I really dont want to go the route of just buying a replacement off ebay if I can get at least one of these fixed, but of course would like to get both of them fixed if possible

I don't know that this is the problem but I have heard of people finding the audio output section on the board and replacing capacitors when there was no/low sound. That is a 'shotgun' approach but might work (or not). It would be a quick and cheap attempt at a fix.

Do other boards have sound in the same cabinet where either/both of the MM were tested? Wait, KLOV shows non-jamma so don't worry about other boards.

I would still wonder about the cabinet wiring / speaker wiring / power supply voltage if both boards behave the same in the same cabinet.
 
I use a jamma adaptor for the games. I have two jamma adaptors for these boards and they dont have sound no matter which adaptor I use. Plus I have a Mania Challenge board which uses the same adpator and the sound works just fine with that board. Other games in the cabinet work just fine as far as sound goes. Hoping to find someone that knows these boards and can fix the problem since I dont know anything about these.

Ok. That rules out the wiring/power issue.
