As Far I know it does NOT support 5.1 .

The optical connectior that we have in MacPro's does not support the 5,1 audio .

Seams that TosLink it's made only for 2.0 things .


BTW if you need to play movies with up to 24 audio tracks you need a multy channels Card . ( there are many in the market very low cost )

A friend asked me if Tos Link connector does support 5.1 . As Far i know it does not , anyone does have different information ?

Cheers
