Ok, I had the same exact problem, except that I have windows vista. I hope that this helps you out because I know it can be a little annoying. First, go to your control panel, then you go to hardware and sound. In the hardware and sound, you will see this thing that says sound. Click sound, and a little screen will pop-up, double click speakers, then another little screen will pop-up. On the first tab, it'll say controller information, then whatever it is, next to it (on the right side) there will be a button that says properties. Click on that, and another screen will pop up, click on the little tab that says driver, and you will see all these options, click on update driver, and maybe it'll work. Hope it works with XP, I kinda doubt that it's the same programs, but it's something.
