The only other thing I can think of is to fool around in your volume control menu. Make sure nothing is muted or turned down. Usually this only applies to analog output but maybe it's different between sound cards. When I go into my volume control I have all the separate channels listed, and some various master controls, I think there's even one for SPDIF specifically.
I know that someones when outputting analog 5.1, if I turn on WinDVD, something gets screwy and I have to close all my programs down and flick mute on and off on a few of the controls before my sound is working properly again. Not sure what causes it but usually for whatever reason my center sound either drops out completely or becomes very low volume wise.
I've never had any problems on my optical port, except the odd time I will get a screaching noise that can be remedied by move the movie ahead a chapter and then back.
Also, within PowerDVD if you go to show information you should check to be sure that DD 5.1 is being spit out. Sometimes the 5.1 track isn't the default audio track played.
It sounds like a driver problem though to me because if you can't get into a specific Creative menu for your card then you can't be sure what your card is trying to do. For SPDIF on my motherboard the driver software has options like speaker setup, SPDIF passthrough, no output, output digital only. And different khz settings. I think the receiver can only understand 48 and 44.1, if it's set to 96 khz I get no sound.
