Need a bit of help getting Apogee 200 to route audio
 

Ok, so I am trying to get the audio out of pro tools back into a screen capture program. I am getting video from a usb cam, I am getting screen capture, but can't get the audio out of pro Tools back into the mac.

I am using the optical adat output on the back of the rosetta 200 and going in to the mac tower. I have set the audio in on the mac pref menu to digital in, but can't get the rosetta to send any audio through the optical cable.

Currently, I have the 200 set and analog in for the mic input, and option out for the playback of pro tools using the X-HD card. What do I need to change to make this work?

Thanks,
Doc
