It always helps to find out someone is running an Audigy 2 "anything". That was one mistake seen on the last build here where the card simply quit. But you are also seeing this with the onboard sound. Did you make sure that was disabled when running the Audigy? If that is still enabled it will directly interfere with any installed card.
Onboard and PCI expansion cards conflict with each other. With XP you will want to install the Audigy card you have there in the second or third pci slot. Problems are known to come up with XP's own resource sharing. This is another thing to look at there.
