It took quite a bit of

It took quite a bit of effort, lots of installing, and even more uninstalling and rebooting, but I finally got the audio working through the X-fi.  In case anyone else decides to do this, here are the important parts:

1.  Let Windows 7 download all the drivers for you automatically
2.  DO NOT run Creative’s Automatic Updater utility
3.  Go to the Creative site and download the Alchemy drivers, as well as the Dolby Digital Live pack
4.  Install Alchemy
5.  Install DDL
6.  Add the game’s path to Alchemy (this may be done automatically through Alchemy combing the registry for you and locating your game paths)

At this point, you should have 5.1 audio going through your SPDIF connection to the receiver and EAX will be available under Windows 7 in your old games.  You will need to disable the HDMI audio when playing games and enable the X-fi, but that’s pretty simple.  Additionally, you may need to switch your receiver to pick up the digital audio from the SPDIF input, rather than the HDMI cable.
