Hello there spy 1 Welcome to SF!
You may have to consider replacing the present card with a newer model at least an Audigy 4 series if not an X-Fi model that sees regular support from Creative. There is a limite number of 7 updates for drivers
and the application available for the Audigy 2 series however.
First you have to select the series and correct model to proceed from the page seen at Creative Worldwide Support
At least one thing can be said for 7 over Vista as far as finding driver
support for the Audigy 2 series! 7 so far has seen far more updates available for many things!
