Post your circuit. I suspect its a ground loop problem injecting noise. The question is where to break it ?

Very often, when connecting from one piece of equipment to another piece of equipment.... you can run into something called ground loops.   This occurs mostly on equipment operated from the AC mains.  To solve ground loops, you can connect small isolation transformers for audio type signals.
