Assuming you are using a version of windows your most likely problem is you have not set up a driver for your sound card...(whether embedded in the motherboard or a seperate board) assuming you have one. If you are not getting a plug and play prompt when you first boot go to your control panel and select add/remove hardware...follow the dialogues from there and be sure to have your sound card CD or your motherboard (if your sound card is embedded in your motherboard) cd handy. Am guessing the former by the way as "if" it was on your motherboard you would have had to have used that CD and it would have installed the driver.

Should be that simple (or complex depending on your experience level)....good luck. Tango
