Advertisements Ok, this is hard to describe. I have a Tivo Roamio Pro routed through a good 5.1 receiver. During scenes in some shows like Chicago PD and various others, the background music/sound turns into this metallic tinny sound that just can't be on purpose. It is definitely part of the scene - when they are trying to make it intense and ominous, but it just sounds like bad tinnitus in the background. Does anyone have something like that?
