Anyone been able to get surround sound working? I used a tool called Indirect Sound for Deus Ex, and it worked pretty well, albeit with some wonky front/rear separation, but at least it had some.

But nothing I've tried in Undying works. With Indirect Sound, the game (with default settings) crashes on startup, and says 3D hardware failed to initialize. That's with Direct3D mode. If I use Glide mode instead, which might be the better option for video quality for this game anyway, it runs, but the sound only comes from my front left and front right. I do have 3D Hardware selected in the Audio options screen. There's a whole bunch of sound options in system.ini that I don't understand and can't find any information on, and experimenting has failed to tell me what most of them do.
