Like the title says, I have one of those 6-in-1 changers like from jammaboards.com and I get no sound on CPS2 boards only when using this. If I bypass the 6-in-1 board everything works fine. Also, all other games work fine when using the 6-in-1 changer. What is it about CPS2 that could be causing this conflict?

Also, I have upped the voltage just to see if that changes anything and it didn't seem to matter. The only thing that seems to be different is that the 6-in-1 changer is not routing -5 volts, so -5 volts does not reach the any connected boards when using the 6-in-1 changer. I checked the "Games that dont work without -5v" thread and someone mentions CPS2 but says it should work when using the mono from the Jamma connector (which is what I'm using).

I'm not sure if it matters or not, but this is for Gigawing A&B board.

Have you tried connecting it to another jamma connector on the 6 in 1 changer?

I would also check what your 12v voltages, that is probably what is causing no sound on the CPS2.
