Experiencing Humming Noise
I just installed an Onkyo HT-R390 surround sound system. I am experiencing a humming noise coming from my sub woofer. I only experience this humming when the DirecTV receiver is set to Dolby Digital. If I turn off Dolby Digital the humming stops. Is there any way to cure this?

To add more, the DirecTV box is connected to the HTR390 via HDMI and HDMI connects the HTR390 to the TV. The subwoofer runs off the AV Reciever, it does not have an independent power source. The AV Reciever, TV and DirecTV box are all two prong plugs.
