Yes, 2018 model. And yes, this happens over ARC and just through the TV speakers themselves.
Long story short, Samsung eventually junked that TV and gave us an in store credit. We ended up purchasing a 2019 Q70 because I just can’t seem to get away from Samsung. Turns out the Q70 starts at a default setting of 100 milliseconds of delay. But like the other TV when streaming Dolby Digital I have to back to delay all the way to 0 and the audio is still a bit behind. Albeit better than the 2018 NU8000. I haven’t don’t any real testing to see how far. The wife has given threats if we continue down the replacement road...
So I’m kind of just dealing with it and hoping there may be firmware updates in the future to improve it.

They sent someone out to replace my motherboard but that did not fix the issue.. It has to be something built into the firmware and I just can't seem to get anyone who understands. Everyone keeps telling me to turn up the delay on the TV!!
SAMSUNG!! Support your product please!!

So this seems to be a fairly common problem that's been popping up out there.. I have a 2018 UN65NU8000. The audio at 0 ms is lagging behind the video. From what I can tell with sync tests around 80 - 100ms. We get all of our content through the onboard apps (Netflix, Hulu, Amazon, Youtube). It seems to be a bit worse using Dolby vs. PCM. We are going out ARC to a Yamaha reciever so I don't want to just set to PCM and loose my center channel etc. Same issue with optical and same issue just using the factory speakers. So I've rulled out reciever issues.
Samsung has sent someone out to replace the motherboard and that didn't fix the issue. I'm fairly certain that there is some sort of built in delay in their firmware that is causing this issue, but I can't get to the right person that understands anything beyond increase the delay setting in the user menu.. which natuarally worsens the problem!
I've read people having success in the advanced service menu. There's a setting called "audio delay" and changing that from 10 to around 3 seems to fix this issue for most folks. Naturally, I don't have that one specific setting in the service menu on this TV!
It just seems so odd that the audio lags behind the video. Obiously it's usually the other way around or we wouln't have all of the audio delay options built into these TV's and recievers.. I'm not finding much help from Samsung on this and I hate to get rid of the TV as I generally really like Samsungs TV's, but I'm running out of hope. Any help that anyone has would be greatly appreciated!! Thanks in advance!
