I believe the white connector is described as "Digital I/O (for stereo SPDIF output to Digital I/O Module
". SPDIF can be, apparently, either optical or copper. I'm not familiar with SPDIF but I think this signal is a digital composite of all the individual channels which a surround sound receiver can decode and output to speakers.
There appears to be different kinds of Audigy 2 cards out there - an exact model number
would help a lot. Does it look like this Audigy 2 Value
