The sound driver for your particular MB/sound chip is an individal driver designed specifically for the MB's sound solution. XP Pro does not have a universal sound driver as you imply. The MB or system CD would have an appropriate sound driver for the system. The online product page would also supply correct sound drivers for your system.
I keep looking for the sound driver but I can't come up with anything. If you can give me more specific information I would be very appreciative.
Thank you for your help.
