lol, i just bought a DS3 rev 1.3 couple days ago. i installed it and thought the sound didnt work. But all you need to do is use the CDs that came with it, either the normal one for XP and 2000, or the other one for Vista. You should install all those chipset drivers, or at least the HD audio driver and the Realtek Codec. It should work after u install those and restart.
