Not even a hum from the speakers. I've verified the speaker works and meter says I have continuity from the board to speaker. I have verified that the chip that plays the background music is producing sound. I'm thinking there is either voltage issue, an amp chip that is dead or a bad pot. Usually though bad pots will give some noise to the speaker even if they're not working correctly. I need to look into the pin out to test voltages. I assume either -5 or +12v are for the sound. Anyone know if bagman uses an amp chip? Also I'm not sure I'm getting any sounds other than back ground music. Is there another sound chip that would effect output if it were bad?
Thanks ahead of time for any input.
 
checks

Look at the voltages first and adjust them.
Check your wiring harness.
Clean the connectors and reseat.
Reseat all the socketed chips.

Post your results with as much details as possible.

Thanks for the reply. these were the first things I checked. All seemed to be fine. I have a tool that allows me to hear if a chip is producing sound. basically the games sounds are all there but are not being amplified off the board. So the amp chip is the most likely culprit.
