Apple TV audio/video sync issues

Lately I’ve been having difficulty with lagging audio to video syncing with my Apple TV 4K. If I restart it, the problem is temporarily fixed, but after about 5 minutes of watching Netflix or hbo now, the audio will start lagging. This doesn’t typically occur with Disney plus or streaming movies from iTunes. Once the audio starts to lag with the service, it continues to lag once I exit the app. The sounds you hear when hovering over different apps lags significantly. Again, this is only fixed by resetting the Apple TV. I have run Netflix through my (smart) TV and had no problems with audio (it’s the same TV I have the Apple TV connected to). I’ve also ensured my internet connection/speed is good (>300Mbs), and have tried connecting my Apple TV to my router via Ethernet cable, with no improvement. This problem has been present for months but has gotten significantly worse recently. Changing between audio formats doesn’t do anything (a suggestion I saw when researching the topic). Please help.

I’ve had an intermittent audio video synch issue with my Apple TV 4K and my LG OLED TV. The issue seems to happen across many different apps and only on the 4K version of the Apple TV. Apple checked into it and said to check with LG. I called LG and was told it is a known issue. The solution they recommended was to turn off the Dolby Atmos and smart sound settings on the LG OLED T V.
