I tried removing triple buffering but it did nothing. its weird because my preview movies have sound for some emulators and others dont when i go into a system menu screen where it lists the games some play sound others dont if the preview emuvideo doesnt have sound then if i choose to play a game it also doesnt have sound if i remove the instant sheller and restart the sound works beautifully on every preview video for every system i have emulators for. i am using soundmax and have tried both the hd audio and ac97 configs and both do the same. i have even tried diffent frontends to see if it is just game ex and they too have the exact same problem. i had a startup video and it played sound for all front ends but when it entered the emulator menu screen and i hightlighted a game the video would play but not the sound for everyone. so i am thinking it has to do with a driver not being loaded or soundmax is f---ing it up. or a service help!!!!
