After over a year of having non-functional features for Aureal Vortex sound cards in Windows XP, I have been contacted by an owner who has been able to patch the driver to override version detection, allowing the native Aureal control panel to function in Windows XP as it did in Windows 2000. You will now be able to have full MIDI control support.
Please note that this patch has not been tested by anyone, so use it at your own risk!
If you find that you have no sound in Windows XP, then please consult this page.
NB: If the download links don't work, try please try right-clicking on them and choosing "Save Target As..."
1. Remove all previous versions of Vortex Control Panel XP
2. Download the AU8820 Applications from:
3. Download the AU20DAL Patch from here
4. Run the AU8820 Applications to install and wait a couple of minutes
5. Next, run the AU20DAL Patch Installer
The problem with the original Aureal Vortex Control Panel is not with the control panel app (au20cpl.exe) itself, since this is cross-platform compatible. It calls an external DLL file (au20dal.dll) which does a version check for either Windows 9x (4.x) or Windows 2000 (5.x). Unfortunately it does not recognise the minor number for Windows XP (5.1). The problem is made worse because the application compatibility wizard cannot handle DLL files, only EXE.
Hlt discovered that by finding out where the version checking routine lies within au20dal.dll and commented it out, which resulted in a fully working control panel!
If you want to patch the file yourself, the instructions are here:
file location:
%systemroot%\system32
file name:
au20dal.dll
file offset: code bytes:
