I tried to connect my vizio soundbar to my TV (UN65RU740DFXZA) via HDMI ARC, and it shows as "Receiver(HDMI)", not "D. In" or "TV ARC" as I read in other posts. I can't enable Dolby Digital Plus in the expert settings and I read the sound output has to be connected via ARC (which it is).
I have checked my connection, TV on HDMI 3 ARC port, soundbar on HDMI OUT ARC port. Tried turn on/off HDMI CEC. None of these help.
Does anyone know why? Should I request a warranty replacement?
