Drivers for all Vortex-based audio products are included with the Windows XP operating system - both Home and Professional versions. It is recommended that you use these drivers only, and no others.
(Note: Microsoft has since updated the drivers for the Aureal Vortex-based sound cards and put these new drivers on the Windows Update site. User feedback has been negative in regards to these new drivers, so it is recommended that you not update to this new version.)
These drivers support digital audio, DirectSound, DS3D, A3D 3.0, MIDI (via DirectMusic), the wavetable header, the joystick port, and S/PDIF Out.
The drivers do not support EAX, A3D 3.0 reverb, or S/PDIF In.
There is also no Control Panel provided. However, a replacement has been created by Chris Day that works under WindowsXP. It can be downloaded from his site.

Why is the Windows XP support so bad?
Aureal never finished their Vortex drivers for Windows 2000 where they were at a point that they were both stable and full-featured. Microsoft has rewritten the drivers for Windows XP based on the last Aureal driver build; these, however, suffer from many of the problems Aureal's did.
