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
