So far, I've tried a little gaming with my Sennheiser HD590s plugged into the card and CMSS-3D headphone enabled. Didn't actually care for it. Apples and oranges between HD590 and HE-5LE though. I also tried that Razer Surround software I came across on some youtube demos.. On youtube, the new Creative SBX and Razer Surround seemed pretty promising. In practice, I couldn't it working right. Again, with no real front back directional cues at all.
I did, just now, go back and set all outputs to 16-bit 48khz, and I stopped getting distortion through What U Hear, and I can run the CMSS-3D headphone surround test in the Creative control panel, and it's not bad. I am a little concerned about all these work around settings degrading quality, but one step at a time.
I cannot find a setting anywhere for "Play Stereo Mix using Digital Output."
EDIT: I was wrong. Even with all output settings at 16/48, louder playback will clip and distort. If I listen to music in foobar and keep foobar's volume slider below half, it isn't really noticeable. If I turn foobar up and my amp down, it sounds like speakers with torn drivers or something. Might be good enough to give CMSS-3D one test run with the HE-5LE though, and just make sure game volume or whatever else is lower so it doesn't clip. I doubt I'm going to change my mind about though, it sounds pretty awful. Also, in all the demos I watched on youtube, loud sounds all seemed like they were happening in a large auditorium, not out doors as the case was most of the time.
