I have a TV/cable box/Home theater system setup: TV; UN60F6300AF HT: HBD-N790W Everything seems to work OK but when I switch an "activity" in my remote, sometimes I lose sound. Going from TV to Smart hub for example, all it does is change the TV input from HDMI1 to Smart hub, it leaves the HT alone. At first I thought it was the HT, but if I change the input on the TV I get sound, same with the HT, if I change input I get sound, this makes me think it's nothing actually wrong with them.. I have changed the Optical cable as well as the HDMI cables. I'm not sure how else to describe or what else I could describe, I just wanted to post to see if anyone had any ideas.
