Sound works on some games/but not the ones I've added

[dunnster]

Hi Guys I got Recalbox up and running no probs with sound(HDMI) on the pre installed roms on the image, I have added a few roms to different systems however none have any sound? i try the pre loaded ROMS that were on the image and they are fine and i have the screen music when choosing system, anyone help out?
Update- all games work including the ones I've added when i change selection to jack with headphones!!

I've tried selecting HDMI out in the menu and also Auto, no luck

Cheers Guys
