upgraded, now my 3ds and nds does not open from launchbox, only from a standalong emulator.... something has gone wrong with this one

As the title describes.. If i play a dreamcast game through lauchbox using retroarch flycast, i get no sound at all, i have tried every audio driver. But if i load retrorach on its own, then everyhting works fine... Only difference i can tell is that, the dreamcast logo loads in retroarch on its on, but not in launch box.. Ami missing a simple setting? Thanks
