However, I remember later I upgraded my motherboard, which of course is my sound chip. I can't remember what I had before, except that it was AC97. My current motherboard uses IDT HD audio (which is no longer supported or updated

Now, I noticed with Uru:CC, I can't enable the EAX. However.....with MOUL:a, I do have EAX just fine (and yah, I have EAX with games like Bioshock, Bioshock2, etc, etc) and it works just fine.
I can't remember if the EAX ever worked in Uru:CC,.....heheheheh, as I wasn't really paying attention.
Can anyone tell me if it works fine? Or is it not enabled? And if not, why in the world would they have that option even listed?
