Thats pretty strange. As far as I know if your sound-card doesn't support hardware accelerated EAX2 it is simply calculated on the CPU. You really should look if you got the newest drivers installed and everything. Just to be sure.

Huh! Don't you mean calculated via sound driver software. Even then it's only very basic but a lot of popular sound cards do support Hardware acceleration but some still don't have EAX2 capabilities. Anyways I will have a go at
getting the software capability support working with OpenAL so don't give up hope yet Ello
