No output reckognition on channels 5/6

Just replaced my Mobo and resetting everything up in Pro Tools. Had to reload whole system. I have all tracks routed to a mix buss 1 and 2, then the mix-buss to Master Fader which is 5/6 out. So the 5/6 out are all grayed out and no audio is going to the master fader or out of the speakers.



Went into i/o and properties and everything looks good as far as I can tell.

What am I missing here? Kinda hard to explain so if you need all my system info and whatnot just let me know. But think it might be because I forgot to set some routing in Pro Tools itself.



Thanks for your help
