4 pin audio connect question

[ingeborgdot]

On the back of the cd drive there is a 4 pin audio connect.  It says to connect the cd drive here to the sound card.  Why would you need to do this?

I believe it is to use the CD-ROM's capability of reading it like a standard audio CD, and just playing the sound instead of having to send the deta to the board, convert to digital, process it, then convert it back to analog. I could be wrong, though.

If your running windows 2k or above dont bother it actually does nothing and you lose sound quality.  Its for the most part useless these days.  Although if you have an old computer running windows 98 and a pentium 2 processer i would do it to make sure the performance hit isnt  to horrible.
