Humming sound when hooking up PS3 component

[Rabidhunter]

What settings do you have on your PS3? What receiver are you using? Have you tried another HDMI cable? Try looking at your speaker wire to the center, maybe use different wire to see if it's still there. What audio options are you selecting from the menu of the movie?

EDIT: I see now that you are using component audio outs. If your receiver has an optical input I would use that instead. But checking your audio options for your PS3 would be the first thing to do.
