I finished installing the GCDual today and have no audio over HDMI. This is the second kit I've installed in separate consoles both with the same issue. I have checked all points with no bridges and continuity between all points. Composite video/audio work great. I also plugged in a EON Mk-2 and video and audio work fine. The blue led flashes in both cases. This kit seamed pretty straight forward compared to the PS1 Digital and DCDigital I've installed. Not sure what the issue is. Any help would be appreciated.
