I have been using Toxiclibs - audiotools with OpenAL to start manipulating sound in space.  However on the Mac I am only getting left-right panning, and not getting any of the 3D sound I was hoping for.

It looks from various posts/websites like I will need an extra sound card before I can get surround sound on the mac.

Has anyone done this successfully?  Even if you have got surround sound working on a Windows setup, please let me know what hardware/software you have used to get it working, as surround sound is core to my project.  As stated in subject line, speakers or headphones both fine, as long as 3D is achieved.

I am on a MacBookPro, 2009 machine (low spec 13") running SnowLeopard.

Thanks :-)
