You might try moving the Wadia's cable to coax 1 on the Onkyo and choosing the receiver input that defaults to coax 1. Just standard troubleshooting practice to see if the problem is unique to the input that you've chosen.
The next step is to choose a different output on the Wadia (if there is one) for the same reason.
Good Luck
