Noise coming from subwoofers and centre channel

Hi,

I have a noise/hum in my subwoofers and only one speaker, the center.

When listening music only, the noise is really low but when watching a movie with the projector and madvr processor, the noise become louder.

Someone have an idea, something common?

Thanks in advance for any help.

Replacing the high quality HDMI cable with brand new modestly priced cable solved the problem. I don't think HDMI is very robust to begin with. Taking your trouble shooting a step further, star grounding, using a power strip into one receptacle and connecting each component one at a time. Plugging additional power strips into the first strip maintaining the single receptacle power source may reveal a grounding issue.
