@Leadwerks - the Audigy cards are indeed crippled on Vista, but the X-Fi drivers they have officially distributed contained the Audigy drivers, they were just disabled.
However, many features of the X-Fi which is sold as "Vista ready" have been disabled aswell. Stuff that works on XP such as Digital output was turned on again by David_K in his revision of the driver, so it's not the ability of Creative which broke it, rather a business decision.
