I have a PacMan 25th Anniversary edition that I have been routing for about 2 years. Has been a solid machine but it just started having an issue where there is no sound at all. I have tried adjusting the volume knob inside the machine, but still no sound. I also tried adjusting the volume knob on the Jamma board but again, no sound.

I am not sure what else to try. I read about sound issues with other Pac Man machines and a fix was replacing an Amp chip. I am not sure if that exists on my board.

Any suggestions would be appreciated. This is a picture of my Jamma board.
