I have tried unplug and plug both machines to no avail. Samsung has a system setting to enable Anynet which is what they call ARC. ARC allows both machines to talk to each other. This is how the 975 is receiving the sound and it is great. I cannot find any reference to an ARC system setting on the 975. There is a "punch through volume" feature, though that seems unrelated.

I have a second smaller setup with another Samsung and a Vizio Soundbar and subwoofer and it works beautifully. Sound not as good, but not terribly bad either.

I am changing volume with the 975 remote and every time I do, there is a silent gap. Same when I change channels. This didn't happen with my old Pioneer VX.

There must be something I'm missing.

Meridian self powered center, right and left speakers plus Meridian 2x10 subwoofer. Surround left and right Polk Audio.
