Part 1 - Install the wrong driver
Yes I know it sounds crazy, but in order to achieve our goal we will be installing the incorrect driver for the Audigy card. Start by going into device manager, and obtaining the properties for the PCI Multimedia Audio Device.
On the Driver tab, click the update driver button and select the "Install from a list or specific location" radio button, and press next.
Then click the "Don't search. I will choose the driver to install" radio button, and press next.
Select "Sound, video and game controllers, and press next. Untick the "Show compatible hardware" box, and from the list select the Creative Soundblaster Live Series driver and press next.
This will install the Audigy as a Live! series card. It will install correctly, but you won't get any sounds at all. A restart is required at this point.
