Are you running XP SP2 or SP3?
> If you're still SP2 you may be missing a Windows driver you needed for High Definition (HD) audio that comes in SP3. It's required by the Realtek HD driver will work

If SP3, see if Windows can find and install the right driver for you. Open Device Manager. Do you see your sound card? (Probably listed with a yellow icon) right click it, select Update Driver and let Windows search for the right driver
