Hi Folks - I am down to my last HDMI board... This one I am getting ready for the Multi.

I built the daughterboard from the files, and have everything connected. Once I realized I had the CSYNC(HS) wire on the wrong side of the resistor video came up working great. I noticed an issue with Audio though. Music and some sound effects work, but I think that samples aren't coming through.

Does anyone have an idea of what wire/pin could be an issue to make it so that JUST the samples weren't coming through HDMI? They come through the JAMMA edge just fine.

Maybe ask marqs directly through discord? I was able to troubleshoot with him on there in the past. Classic Gaming Discord: https://discord.gg/UDu5ztY

FWIW, here's my CPS1 HDMI install pics:
