parawizard :
so anything that isn't in native Dolby or DTS format will have to be played to your surround sound with analog 3.5mm RCA plugs. Thus anything but basically movies on your computer that come with native DD or DTS you will have to use analog on a creative card cause the digital out is just a passthrough.
Did you make this up? Or do you have a link?
When using the fiber optic or digital coax cables from the X-Fi Fatal1ty every non Dolby/DTS sound my computer makes is recieved as stereo by my Z-5500's.
I copy and pasted some points made by the author Brian Gray from the link you provided and the fourm discussion linked in the article.

From the article you linked.
"A quick note here - when in Dolby Digital Live mode, the analog ouputs are disabled. This may give insight into how the system work, as it would seem reasonable that the analog signals are rerouted from the discrete channel outputs into the hardware encoder. This is the basis for one of the complaints audio purists have with DDL. You have to add another analog to digital conversion, there by inducing some compression loss. The only time this compression loss has an opportunity to be noticed is in situations where each of the six channels is running at higher output levels. Is it an actual complaint for most users, no, and moreover the instances where the encoding "loss" could happen when gaming will be moments too frenzied for the gamer to perceive the inaccuracy."
"I am extremely happy to have one great feature, that NVIDIA should have kept alive, back in my system. Dolby Digital Live will give HTPC owners and gamers that just hate having the cable rat's nest to their speaker speakers and opportunity to simplify the connection between their speaker system and sound card."
From the fourm.

No, DDL does not just receive two channels and upmix. The sound card receives the six channel information from the game, just as an Audigy would, and then encodes it into a Dolby Digital stream. HUGE difference.
What DDL adds is the ability to eliminate all of the cables from the sound card to the tuner by encoding to DD. In my case, I do not have the six channel inputs, so DDL is the only way for me to have true surround sound gaming, which makes a major difference in Doom3 and HL2.

The fourm goes on to suggest that the HDA X-Mystique 7.1 Gold is outperformed by the Audigy2 in games, only supports Eax 1.0 + 2.0 and has no OpenAL support.
Based on the impression given by the article and fourm I'd say that the HDA X-Mystique 7.1 Gold would be a bad purchace for gaming then(2005) and a horrible purchace today.(X-Fi > Audigy2 > X-Mystique)
The author Brian Gray would have really liked the Z-5500's. The included 6-channel direct cable is one piece so no "rat's nest" and the six channel inputs would eliminate his need to compress audio into a digital form to have surround sound gaming.
