I think he means that he add/removed his SoundMax drivers. You will have to go to the maker of you computer (Is it a Compaq?) and download the driver again. Or get the numbers from the card and go to a place like driverguide and find the right driver for your card.
If you can find the pertinent numbers on your card but can't find the drivers, I will help. Just post all the part numbers you can find on the card. If its onboard sound, you will find a chip on the motherboard with ADI on it (I think). Just copy the numbers from under the name. (I.E. ADI 1881)
