I'm having an odd issue with the aforementioned system, the A/V receiver is a RCA STAV-4180 unit, and being from 1996, it's still a great unit. So far, while it's tape output for recording does have noise coupling issues, none of the inputs do. The buzzing only happens with the PS2 and goes away when the PS2 is turned off. I've done a lot of troubleshooting and can't find anywhere else that the buzzing is coming from. Any tips? I think the cable itself may be the point of ingress for the interference, but am unsure.
