I built the 10” display picade yesterday, installed the xHat software and it’s is running retropie games ok with sound through the speaker. The issue I have is that there is no sound in the retropie menus or the video splash screen I set up to play on boot. When I go to audio settings in retropie it says “on-board audio disabled or not present”.
When I unplug the picade screen and plug the pi into my tv via hdmi everything has sound fine, so guessing the issue is retropie/emulation station is using hdmi for sound and not the speaker. Not quite sure what to do from here to have universal sound via the speaker. I would appreciate any help please.
