Q90T and Q90R sound off sync

[xrob513x]

Hey everyone. Sorry if this is answered before. Tried to find, but couldn't. 

Currently have the Samsung Q90T tv and Q90R sound bar. Everything is hooked up through my Apple TV. Trying to find the best wiring set up to get rid of the sound being off sync. Right now I have the apple tv connected to HDMI 1 on the sound bar and the ARC connected to the ARC on the tv.

I have messed with different set up configurations and also the sound settings on both the TV and the sound bar that I have read on different threads here and on other sites, but the issue is still there. Now, I will say, some channels are manageable to watch but some are off like crazy.

But yea, any help would be appreciated.

Have you tried turning off Dolby Atmos via the TV Settings with regard to Audio see is this helps?

That did help a little. Does that mean Dolby atmos won’t work when watching supported video?

Does this occur on everything Live TV etc?

It happens with live tv, recorded stuff and streaming apps, but it is way more noticeable on live tv, more specifically local channels.  When I stream on netflix or hbo max ect.. it is pretty close to being correct.
