this was needed on mother boards that didn't support digital audio. Most CD drives still have the plug/cable for the older systems.

I was wondering what is the exact purpose of the CD-ROM Audio cable? The cable is gray, with a 4 pin plug on both sides but only has three wires occupying the ports on some cables, and all 4 occupied on others. The inside wire colors are Red, Yellow, White, and Black, and connect onto the Audio port on the back of the CD-ROM near the IDE cable, and connect usually to the rear of the motherboard for Audio.
I have left this cable unplugged in the past, and have never noticed a difference in sound quality from music CD's being played from the system.
Does this cable even serve an audio purpose anymore? Is it a legacy device from the earlier days of DOS and Windows 3.xx? Or does it serve a superior purpose for audiophiles and those that work in some sound industry?
Thanks in advanced to your answers!
