Ground Loop problem. Subwoofer hum. Will this gound isolater work on HD

[Denvers Dawgs]

I am suddenly having a ground loop problem. The cable is causing my subwoofer to hum on my Home Theater system. If I unplug the cable all is fine. I tried to use a $10 ground loop isolator from a local store, which did stop the humming, but it also disrupted my digital/HD cable to the tv, to the point of unwatchable because of constant stuttering/pausing. I was wondering if anyone know's if an Isolator like this would work, and still keep the video quality as it should be?

The loop is probably caused by plugging power into separate circuit breakers. Plug in power to the same circuit where possible. Think back which connections were made recently.

Yeah try different AC outlets or run a wire between the sub chassis and the amp,an Isobar powerstrip may also help.

I have tried to plug the subwoofer into the same powerstrip that has the tv, HT system, cable. And I also tried to plug the sub into a different ac outlet and it still did the humming.

I haven't changed anything with the setup. It just one day started humming.
