Shatnorsk disable "play in background in Cubase". It seems like the sound driver is still being used by it when you attemp to play the game or you will have to reboot then launch SFP then the game.
Ive tried this and it doesnt work, and with the rebooting, it doesnt help also.I have some info which might make this easier to search.If I play an mp3 without running SFP I get a message about a sounddriver not ready or not responding.But if SFP is running mp3s work there is just no sound
I have also solved this prob on a friend's luna sys with this steps:
1. install or reinstall directx 8.1a
2. enable cd digital output from cd properties in device manager...
It's a very strange bug, and i can't explain it technically...
