OpenAL only games like Geas of War work of course, just not originally for DS3D made games that need Alchemy.
From what I've heard about the way DS3DGX (and possibly Xear3D on other C-Media cards) works, it drops a dsound.dll right into one of the Windows system folders, so you don't have to manually set it for every game like ALchemy (which instead copies the dsound.dll wrapper file right into the game executable directory for each and every game). This may mean that it's prioritizing the one in the Windows system folder.
I wish I could help out more, but I don't have any Xonar or other C-Media cards around to experiment with. Good luck with your testing.
(Oh, and could you be sure to test out Battlefield 2 or 2142 on the Essence STX? They use OpenAL, but the best sound settings are tailored to the X-Fi DSP, and it appears to use EAX 5 as opposed to EFX.)

The myth is busted:
-Myth: Sound card DSP effects for gaming do not carry through S/PDIF.
-Fact: They do go through S/PDIF. I've tested it myself with RightMark 3DSound's positional audio test (uses DirectSound3D, so be sure to point ALchemy or other wrappers to the installation directory). This makes the combination of a sound card as a DSP and an external DAC with S/PDIF input a plausible upgrade option, as the sound card's lesser analog circuitry is still bypassed.
However, arbitrary driver decisions may prevent some DSP features from working over S/PDIF anyway, such as Dolby Headphone on Xonar cards. This does not apply to all cards; X-Fi cards allow CMSS-3D Headphone output over S/PDIF.
I can't believe I didn't see this in over a week...I've updated that part of the guide to point to your post.
