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.

My HDMI is connected between my projector and processus and then, it to my AVR. Where do we connect this isolator? Thanks
