Setting up my MacBook Pro on an DVI to HDMI cable to a Sony LCD TV. I have a Bose surround plugged in to the audio out on the laptop. "headphones" When ever I plug in the HDMI cable to the TV. I get loud static on the speakers. It's mostly there when there is nothing playing from the laptop. If I'm playing iTunes and pause it, the static slowly builds up in volume and it won't stop unless I play iTunes again. I tested this on 3 laptops and it is the same problem. Any help appreciated.
