Isolated Ground causes ground hum.


Hi Experienced Goner.
I am adding the isolated ground into my music system and when I connected the ground wire into my existing system and it hums badly.
Did I do st wrong?
 Thanks

I stand under correction but i Have found that if all are common ground with good rca cables that should sort it unless one of your devices has a switch mode power supply, that can cause chaos!
