I've looked everywhere and can't seem to find an answer to why my Black Hole sound isn't working. I've had the game for a while now and finally have the game playing after installing a new Pascal Janin all in one board. The guy who had the game before me said the sound was working for him, but it never did for me. Maybe he meant "it worked a while ago".
I've re-capped the sound/speech board, and the sound board's power supply. I have 30volts at pin 10, and I get humming from the speakers when I adjust the volume pot but nothing happens when I hit the test button. I've tried grounding pins 2, 8, 9, 11, 12 on the sound board and still no sound, but I do get some light static as the sound attempts to play for a few seconds. I've re-seated all the socketed IC's and they seem to grab on nice and tight. My connectors look like they're in good shape with no burning or corrosion, and they grab the boards very tightly.
I'm not sure what to do next, and I hope someone can steer me in the right direction. Thanks!
