Here is the problem. I have an old gateway laptop (model number MX6437) that had issue's and needed a re-format. Since doing so, the sound does not work. I am unable to find a working driver. I have checked the gateway website as well as the realtek website for the AC 97 driver that the card seems to use. Every driver I attempt to install goes thru the setup and fails no matter what. Part of the issue could very well be that I do not have XP sp2 installed. I cannot get SP2 because Microsoft all of a sudden in the last couple years decided to add a verification to check for authenticity of your XP installation. My XP SP2 disk was lost about a year ago when I moved, and I was forced to use a copied version of XP sp1, and I cannot update to SP2 because the computer will fail verification. I have a feeling this is why the driver does not work, if anyone knows of another driver that may actually work, I would appreciate a link or information.
