I am breaking my brain here and can't seem to find any clear information regarding my problem with FCPx. I want to monitor my audio in 5.1 but can only do it in 2.0. How is this possible? I have tried the Toslink to optical and it works with Quicktime or VLC but not in FCPx. I have tried Thunderbolt HDMI to a receiver and once again, no 5.1 I have found tidbits of information about using an external audio card to monitor in 5.1 and have tried a cheapo Zalman zm-rssc v2 card but that did not work either. Am I going to have to spend some serious coin? Please help!
