All of a sudden, my center speaker seems off. I was trying out my new TV with Dark Knight on the PS3 and everything was fine except for the voices, they were almost completely gone. I said forget it yesterday and went to sleep and today I get better sound but it sounds different, a little muffled. I used the 5.1 speakers Windows test and clicked on each one of the speakers and they sound fine, strong volume. Maybe it was because it was working so badly yesterday that now I'm paranoid and it think it sounds muffled, I don't know, but it definitely sounds off to me.
