Sub woofer on 5.1 Home theater ringing like feedback?

I recently upgraded my DVD player to a blu ray and kept my existing 10 year old Yamaha R-V902 5.1 system. The issue is that the Sub woofer has a ring like feedback that started after a couple of movies that I watched and now is constant. It happens with both DVD’s and Blu Ray disks playing through 5.1 but not when I route the audio through the CD. The ring stops when the disks are paused. The Blu Ray player has 7.1 in the back that I hooked to my receiver using RCAs since that is my only option. It is not a hum but a definite ring like feedback. I was just wondering if anyone had this kind of issue before? I am wondering if the receiver is having issues with the new signal or if something is failing. Any and all insight would be very helpful. I do not mind upgrading if needed but would prefer to get some more mileage out of my receiver so I can get more bang for my buck down the road.

It’s called a feedback loop.

Try plugging the sub and receiver into different power strips. That should solve the problem.
