I have a new Samsung Smart TV hooked up to a new Denon receiver thru the HDMI ARC port. Works great. But when I try to use an app (like Netflix) I get Netflix sound from the tv and the channel that had been playing on the tv thru the surround sound. If I switch the receiver from CBL/SAT to TV AUDIO it works but I also then have to switch the sound to surround. Shouldn't I be able to seamlessly watch Netflix and hear it from the surround without having to do that? Did I hook something up incorrectly or maybe forget to hook up something? I would appreciate any help or suggestions! Thanks!
