Not detecting audio CDs

I have a windows 98 computer that is not detecting audio cds. The audio cable is connected from the back of the cd player to the sound card (which happens to be integrated on the main board). I have also tried changing cd-rom drives. Every application I try to use (media player, real juke box, windows cd player) all tell me to insert an audio cd, even though it is already in the drive. When I look at the drive in exploerer, it says there IS an audio cd in the drive.

Any clues?
Thanks
