I am using a Samsung Smart TV with ARC to an Emotiva RM-100 processor. I am using Samsung's "smart box" in between the two. From this box to the TV I use Samsung's special cable to connect to the TVs Arc connection. From the box I go HDMI to my Emotiva's HDMI ARC connection. Then from the cable box I go to the Emotiva's HDMI 1 and all my interconnects go to amplifiers and from the amps I connect to the speakers. My problem is two fold. First I get sound drop outs not video just sound. Second when the station switches between the program and commercials which have different audio setting like 5.1 to 2 channel there is a momentary sound drop out which I assume is HDMI reconnecting to the new sound arrangement. The first issue is the worst but then second is just as annoying.
