spacesurfer, did you install the XP CMedia drivers or did you just point Vista to the driver files after installing another set? The reason I ask is that, like nitroshift I had the flexbass package installed but wanted the Xear3D mixer. I uninstalled those drivers and installed the most recent XP ones from the CMedia site (ran the installer in compatibility mode for XP SP2). The device appears correctly in Device Manager but I have no sound and I can't open the Xear3D control panel (rundll32 crashes). (I've got the 9880 also)
