| Check every connection a few times over, and do it methodically. Not trying to tell you how to do things here, just saying it sounds very much like a hardware problem if you ask me. Perhaps even your Digidesign unit is at fault, but again, take your time and source out the issue.
If everything traces fine back to your convertors (Whatever you may be using) then try the same thing on a different pair of outputs (7-8 Output instead of 1-2 for examplle).
Keep us posted

If it is indeed a software problem, then I would have to suggest contacting the manufacturer (Digi) and getting some insight as to the issue. If you don't have time for that, then consider wiping the computer, cleaning it till it shines, and reinstalling a clean os |
