Optical Out + Logitech Z-5500
I was thinking about getting the Logitech Z-5500 speakers which have an optical input, which is here:

I have the Logitech X-530's right now, which are just fine but in order to get the best use of them (meaning 5.1 support) I had to get the Griffin FireWave as well. I've some issues with the FireWave - it works great when it does work, but everytime I restart/turn on/wake up my machine I have to unplug the FireWave and jumpstart it, and it's also somewhat of a hassle because if my computer is asleep and Alarm Clock goes off there is no sound until I jump start it then open up FireWave.app and redo all the settings.
Anyway back to the Z-5500 speakers I was wondering exactly what to do with them in order for them to work properly on the mac pro. Is it just a matter of purchasing an optical cable and hooking it up that way, then having full 5.1/6.1 output with no other hassles or is it a bit more complicated than that? Also I've looked around the forums and saw that people have been having problems not being able to use the volume keys on the keyboard and was wondering if this is true (I also ordered the new wired Keyboard today.)
Thanks for your time and I hope this will help answer my questions as well as anyone else that has them.
