Hey guys, I've been searching macrumors and google for some time trying to figure out how to get 5.1 working on my 2010 MBP......I bought the min-toslink(S/PDIF) to regular toslink and audio works, but 5.1 is not setup. I've opened up Audio MIDI setup and its blanked out, its set at Digital out, but still 2 speakers, I tried Encoded Digital but that does nothing. Any help?
