Ordered this board today
Very nice guide i must say. I have one thought tho:
I read the manual and it says that you can get 5.1 audio trough the three ports on the back: green (line out), blue (line in), pink (mic). In Windows XP you can choose in the driver-settings to switch all ports to output, for 5.1 i have to connect three connectors to the board.

Any chance this will work in OS X?
Would be really great if so!
