Just bought one of these guys, and it's able to stream 1080p video across my house, but now there's a soft buzzing noise coming from my speakers. I'm guessing it's interference from my powerlines? The picture OTOH looks to be perfect quality.
How do I fix it? Is it a faulty device? Do I need to run it through a power cleaner? Is it unavoidable?
One outlet is attached to one of the adapters and nothing else, the other one shares an outlet with my TV.
