EAX?

I've seen no documentation on your site regarding EAX support in Callisto.

However, I found the following Nitrogen D2 PDF:

that seems to say that the chip (or rather the software Xear) supports EAX 1.0 and 2.0.

Can you confirm/deny?

Answer from Aaron Franks, per mail:

As far as gaming goes, Callisto supports EAX 2.0, but the higher versions of EAX are proprietary and only available on a few, more expensive, sound cards. EAX 2.0 will work great "out of the box" for almost every game, but you might have to change the audio settings in a few games for the best experience.
