Naomi 2 no sound

[mltv]

Hey folks,

One of my naomi2 mobos isnt outputting any sound - I worked backwards first - replaced speakers/sound amp/cables, and then finally tried a speaker directly connected to the naomi2 - no sound output at all. Everything else works fine - video and game play all work perfect. I tried searching, but found alot of the opposite (no picture, but sound), so I apologize if there are other posts that detail this (just link me to 'em).

So, does anyone know what I should try next? Can it be the filter board? I have spares I can try. Or anything with caps, etc?

thanks!

You could certainly try changing the filter board. It can't hurt, and might fix it.

Any chance you have a Capcom I/O board that you can try to output via JAMMA audio? Also, check settings whether it is stereo or monoaural. Clear your settings in test mode before you do any surgery. Might be simple. Even try adjusting your voltages. Here is one post where someone fixed the no sound issue. However, it seems to be amp related:
