I don't have that card, but since no one has responded....
Try giving more details.
What are you connecting your Audigy to? Analog 6.1 Speakers, Digital Speakers, Digital Receiver, External Decoder, AV Amplifier? Are they Creative Speakers?
For digital output you use an 3.5mm to RCA adapter. The live drive probably also has an RCA spdif and an optical port.
Some of the analog jacks are regular 3 pole (2 channel) 3.5mm jacks and some are 4 pole (3 channel) jacks.
The 4 pole jacks are designed to work with Creative Speakers, if you need to access the 3rd channel on a jack you will need some sort of adapter.
Download the manual, it will tell which channels are on what jack.
