Splatterhouse PCB issue Please give me some direction here
I have a Splatterhouse PCB and have it hooked up through a standard jamma harness.
When I power up the board the video is perfect. The problem that I am having is the sound isn't working. But when I disconnect the speaker molex connection and reconnect it the sound comes on.
Now I checked to verify that the jamma harness connections are good so I connected the harness to different PCB (Battletoads, Spiderman) and the sound comes on with no problem at all.
Can someone let me know what the problem might be.
I really don't want to have to disconnect and reconnect the speaker molex everytime on the Splatterhouse to get the sound to work.
Im thinking a ground issue but im not sure exactly where due to the jamma harness working without issues on the other jamma PCB.
Im scratching my head here.
Any help would be appreciated.
