[Openal] Implementing a Mac-based system

[Matthew Tata]

Hi,

I use OpenAL in conjunction with a Creative soundcards and speakers  
to do auditory research.  We're transitioning our entire lab (slowly)  
to Apple computers and I need some advice on the hardware setup.   
Most of what we do requires using Powerbooks and Macbook Pros, which  
have optical digital audio out.  Last I heard these only supported 5.1.

1.  Does the digital output from a Macbook Pro handle 7.1 speakers?
2. Do I need an entirely new system with a digital tuner and  
speakers, or is there a way to use my existing Creative S750 speakers?
3.  What is the approximate latency between when my code calls for a  
source to play and when the sound actually plays with such a system?  
I need it to be reliably +/- 2 ms or less.

I greatly appreciate all the help I've gotten from this forum.   
Thanks yet again.

Regards,

Matt
