I'm using a Sound Blaster Live Value and I've connected a toslink fiber optic sender to the sp/dif connection on the card. I'm using WinDVD 3.0 and a 12X DVD ROM, PIII 500, 256MB and the system has both Win98 and Win2000. I get a perfect PCM signal (Digital Stereo Audio) from the setup, but when I set WinDVD for sp/dif to get a Dolby Digital signal I get nothing at all on my receiver. Any Ideas???
