No go. Changed the reg value and nothing changed. I installed the 8 channel version of PowerDVD and that didn't change anything. Finally, installed WinDVD Platinum. Can't get Zoom Player to talk to it either. All of the above play Dolby Digital in the native player, and Dolby Prologic II in Zoom Player, but none will play Dolby Digital in Zoom Player. I tried every setting possible in Zoom Player. If I simply choose 'Exernal, WinDVD SP/DIF Output' it doesn't work. If I go to the Manual Filters and choose the Default WaveOut Device or M Audio Delta AP S/PDIF Device then I get the option in the filter prefs to choose S/PDIF out, but I get no sound. If I choose any of the DirectSound Devices, I get sound, but the S/PDIF option is greyed out. Didn't know this crap was rocket science.
I purchased the AudioPhile 2496 after hearing so much about it on this board. Now I wonder if it's the cards fault, and no one responds to any questions I've asked related to it. Is everyone to busy trying to get it to work, or did I buy the wrong card? I'm happy to purchase a different one if I know it works...
