    Hello, I am at a loss on where else to look for a solution for my issue so I figured I'd post it here in hopes that one of you can help me figure this out. I am not sure if the Apple TV is to blame or not.

    Here is my equipment list:

    Apple TV 4K
    Vizio 5.1.4 Atmos Sound Bar
    2016 Vizio M65-C1

    The Apple TV is connected to the Soundbar via HDMI and the soundbar is connected to the TV via HDMI through the ARC port.

    Finally, the problem in question

    Whenever I watch a show on Netflix or HBO NOW, the audio in the menu screens (and even the trailers that play before HBO shows) comes through fine. However, once the actual show/movie starts, center channel audio seemingly drops out. It usually resolves itself if I hit "menu" on the remote, swipe around until I hear the click/menu sounds and then jump back into the show.

    Does anyone else have a similar issue? Any ideas on how to fix it?

    Do you have the same issue if you disable Atmos on the ATV?

    What kind of HDMI cable are you using? I was using an old HDMI cable with my 2018 Vizio and it was causing all sorts of issues when I had Dolby enabled. Make sure you have a high speed cable going for both your connections. The Belkin Ultra HD cable works great.

    Check your HDMI cable. I had issues with Dolby Vision/Atmos until I bought a newer/better HDMI cable. (Still a cheap Monoprice one, just a newer cheap Monoprice one rated for Dolby.)

    Cable seems to have fixed it. I guess the Vizio supplied cable that came with the system was not up to the task of handling Atmos.
