Is it really random or is it just switching to your ARC input port on the receiver? With ANynet enabled, mine will auto switch to the ARC port on the receiver, whenever I enter a Smart TV app and go back to the input I was ne, when I exit the app. Otherwise, the only time it switches is when I first turn everything on. When the ARC connection is first made with my receiver(Denon), the Denon needlessly insists on changing to the ARC port, even tho I haven't goen to the Smart TV section. I have to manually jump back to the normal input. This is a Denon issue, not a Samsung issue tho.
