thats nice, but when you're playing a CD, you need an actual cable going from the cdrom drive to the sound card. on your cdrom drive there should be 4 things - ide cable, power cable, jumper, and audio cable. you DO have a sound card, its integrated. i guess i should have been more verbose in my description ... sound "controller"... and no, you dont hear everything just fine, you dont hear CDs. so no, i am not crazy, check the cable inside your computer.
