have you tried using the MII in a different location/room/outlet (if on AC adaptor).
How about running on batteries?
Any evidence of someone inside the unit? Maybe left some shielding out? My MI Poly has a huge flat shield under the main PCB and another above the Chorus Board.
Any shielding wires unhooked?
Does the sound change when the LED's change or program change/parameter changes?
Can you record the noise and post it?
