I'm thinking of 2 things; driver issues and settings. There are settings in third party applications that can give it different sound effects; hallowed hall, echo, dripping water, etc. I've seen them before but never used them. I don't think it's available in a native XP install however. I would suggest finding the current drivers, uninstall the current one, and install the new one. Go to the device manager and find "Sound, Video and Game Controllers" and find the your card and uninstall/reinstall driver.
