The best thing to do with this is to install the drivers from the install disk that came with your Audigy 2 ZS, then to update them using the Creative web update ON THE US WEBSITE.
You will find that it will then work OK. The UK site does not show any updates and you MUST make sure that you get the update done automatically from the US site at
http://us.creative.com/support/downl...DspLangID=1033.
Select the section on the left that says software Autoupdate.
