Manuel Jander sent in the following about 2 weeks ago (if it’s already out ofdate I apologize, I’m still catching up on my e-mail backlog):
I’m pleased to announce that we managed to get the 3D hardware processorof the Aureal Vortex based soundcards to work. Now we only need to hookit up into OpenAL, or some other user library and we are ready for 3Dsound on Linux ;)
The specific features: 16 sources with HRTF, ITD, ILD and atmosphericfiltering and a crosstalk canceler.
The latest code still isn’t integrated into ALSA, since its notfunctionality to users yet, but all requirements to make it be are setin place.
If you are interested in help hacking, here is the latest snapshot:

I hope to be able to announce a Vortex enabled OpenAL soon.
