You would think, but the other half of DS3D/OpenAL configuration is setting up the speaker/headphone configuration on the sound card driver side of things so that it knows how to mix things properly.
Keep in mind that Anarion is firmly in the "stereo speaker mode sounds way better than headphone mode" camp, while I'm in the "stereo speaker and headphone modes sound exactly alike with virtual surround off, except in games where not using headphone mode = screwed-up positional audio cues because they're meant for speakers" camp.
Sound Core3D drivers might also handle things differently from X-Fi drivers in ways I can't foresee, especially if the PCIe cards behave quite a bit differently from the Recon3D USB.
All I can say is to experiment and find out what works best for you. The rest of us can give you ideas and tips that have worked for us, but we don't have your ears and sense of hearing now, do we?
