I have an MX300 card and am using the latest Aureal reference drivers (2048) on Windows 98 and latest a3ddrivers.exe (3.12). Have DirectX7.0A as well. Well I cannot enable 3d sound. When I click it under options to turn it ON from OFF it takes a second then doesn't toggle to ON. It stays OFF after clicking like its not possible to enable it. Has anyone gotten the Aureal drivers to work with Diablo. Dumb thing is I tried some Demos like Deep Space 9 and Star Trek Armada and they have no problem using the Aureal 2.0 3d sound. Didn't even have to enable it, it was on by default. Only thing I can think of is that I installed the game before installing the sound card and drivers. But I did run the Test program again.
