I have a 7.1 surround setup using Creative's T7900 speaker system and a Creative Audigy 2 Platinum ZS card. The cable hooking into subwoofer/amplifier has the usual connectors (orange/black/green/grey) but only three run to the card, the grey being terminated. This setup is unique to Creative apparently. Their top-of-the-range Gigaworks 7.1 system uses the same 4/3 setup. I have a second rig which connects to the same speaker system , with a Creative Extreme-Music card which only provides 5.1 surround. 7.1 is supported but needs the fourth grey connector to activate the side speakers. I've tried to contact Creative about this and failed & there's nothing on their website. Does anyone have a solution? Is there a 4/4 cable available to replace the 4/3 which would work with both cards?
