After Windows Vista came out in January 2007, owners of Sound Blaster Xi-Fi sound cards were distressed to find that Creative had left several features out of its Vista drivers. When successive driver updates failed to bring back the features, a Creative forum member known as Daniel_K got to work, but his efforts didn't go over well with the company at first.
Now, over a year and a half later, Creative has finally released a batch of official Vista X-Fi drivers that brings back some of the missing functionality. In Creative's words, X-Fi models whose Windows XP drivers support Dolby Digital and DTS decoding functionality should now have those capabilities in Vista. The same goes for DVD-Audio playback, although the new drivers only restore that feature for 32-bit versions of Windows Vista. Creative doesn't say whether Daniel_K has become involved in official driver development, as the firm suggested he could.
You can grab the 59MB driver pack from Creative's support site. You'll also find a new version of the Console Launcher—a required download for users who want to use the skinned Creative control panel—on the same page as the drivers.
