Sound blaster Audigy and 7.1 sound

[Metalwolf]

Hey guys, I just purchased a Sound Blaster Audigy SE and I'm trying to set it up in 7.1 but I cant find how. I believe the digital sound jack was supposed to work as a 4th analog jack but I cant find the settings. I'll keep looking but it would be nice if you guys could save me some time by helping out. Thanks!

Sorry, I just took a good look in the manual. The digital IO jack is only for digital IO. jut I need a special cable for one of the other jacks. Anyone know where could get a cable like shown that splits to two jacks?
