I assume the audio output of the satellite box is through 2 "RCA" connectors that you run to the wall plate. If that's the case, find something else with audio inputs (like a "boom box") and run the audio into that.
If you can hear it there, the problem is the Concertone or the wiring of the wall plate.
If you still can't hear it, the satellite box is the problem.
This assumes the Concertone plays all the other audio inputs OK, right?
