You should see something listed under "sound,video, game controllers" under device manager. If you don't I suspect you will need to load the drivers for either the mobo sound chipset or the stand alone card you have. I have yet to see any kind of sound that was already on/in the box not work after a fresh install of XP. YES, stranger things have happened, just quoting my experience. Do you see a volume control in your system tray?
