multiple sources but subwoofer buzz on only one. (1 Viewer)

So I have several sources, all of which work flawlessly with my stereo with no interference with the exception of the PS3 which has a pretty substantial buzz coming from the subwoofer anytime I am tryin to watch a Blu-ray. the 360 works, the Directv works, the wii, all work with no interference, what would explain this prblem ONLY happening on the PS3?

Are they all plugged into the same location? How are they connected to the receiver?

all are connected to my onkyo receiver via HDMI and all are run into a power center/ protection deal. the sub is run from an NHT amp that is run into trigger plug on the back of the onkyo. the sub is an NHT 10" ported. the noise is very minimal and turning the box around almost fixes the issue, just dont really want to do this as the sub and port are both on the front side.
