I have a quick question, is there a sound card out there for a Mac Pro that supports 6 channel direct and digital optical? I know the current Mac Pros already support that but not 6 channel direct. Any links would be greatly appreciated, thanks!
To my knowledge, there isn't a multi-channel sound card that has supported OS X drivers. That said, once I get a Mac Pro, I'll probably be getting the Sound Blaster X-Fi Titanium HD PCI-e card by Creative for use in bootcamp, as Creative sound cards are only supported for Windows. Here is a link to the new card. It's slated for release anytime now:

Unfortunately, I know the reputation that Creative has, and it's not good, and I know there are many people who will probably not recommend them. Their driver support is sh*t, even on Windows. I'm not that huge of a Creative fan myself, but as far as options go, consumers really don't have too much of a choice in the consumer sound card market. I only plan to use the card for gaming under bootcamp and I get the results I need for that.
But to ultimately answer your question, I doubt you will find any consumer grade 6 channel direct via 1/8" output sound card that you can hook up to your desktop surround system and expect surround support. Driver support just isn't there.
But maybe with the new announcement of Steam, sound card manufacturers like Creative may yet soon change their stance on the Mac platform. I'm hoping anyway...
The only type of surround sound you're likely to get, aside from the AC3 signal via digital out, is to step up to professional audio interfaces, but that will cost you a hefty amount, as you'll have to have powered speakers to connect to, which don't come cheap as satellites.
Hope that helps, and sorry if my answer is a little bit convoluted.

Edit: Here is a forum discussion of the card:

Unfortunately, it's quite expensive and again, Creative products are always under fire by it's users due to lack of support. I'd actually like to see some other alternatives to Creative myself.
