Another One for the "Lip Sync" Collection

I have a Samsung S90D, an Apple TV 4K, and a Sonos Beam. I've tried every possible setting, including the pass-through option on the TV. I'm using a high-quality HDMI 2.1 cable, but nothing seems to fix the issue.

At this point, I've tried everything, and my Apple TV feels useless because I simply can't tolerate the delay.

Does anyone have any good ideas?
