It has been a LONG time since I broke out my Hyper64 systems... I wanted to show them to my son and... Of course, no sound. I read as many posts on here as I could find, and the general consensus is you don't get sound over Jamma (without the mod).

I'm pretty sure I have a Rev 1 board (B1, FF:WA, and SS64 all work) with the two molex connectors and black volume knob. I'm hooking it up to a Neo Geo JP Candy machine (and a mini, same in both).

The interesting thing is... I do get sound, but it's INCREDIBLY low volume. The black knob (and the random blue pot next to the Jamma connector) do nothing.

Any ideas why this is? Am I misunderstanding and there's something I can/should do to get sound over Jamma without the mod?

I have the rev 1, and wired the auxiliary stereo audio connector on the side of the unit with stereo RCA jacks. I added the jacks to the cable it comes with.
