Hello everyone. I recently bought a new Samsung TV. A 2025 model U8000F. When I use the Samsung TV app to stream video the sound gets out of sync with the video very often. Usually after an ad or commercial. It looks like watching a foreign film dubbed to English. I can swap channels and swap back and it fixes itself until the next commercial or ad. Is there a way to stop this from happening? 

It is not my internet connection because if I plug in a Roku it works fine. Also some of the built-in apps on the TV work fine without issues such as YouTube, Netflix, and Tubi. So far this issue only happens with the Samsung TV app and the Pluto app in the TV. However the Pluto app works fine with my Roku plugged into HDMI on the same TV. Is Samsung TV app just a mess that needs developer work, or could there be a way to resolve this myself? Thank you.

If you have tried all the troubleshooting steps in the link. There are 3 more steps we can take to help resolve this. I recommend performing a Smart Hub reset on the TV. This should help resolve any glitches with applications.
2018 and earlier: Navigate to Settings, and then select Support. Select Self Diagnosis, and then select Reset Smart Hub.

2019 and later: Navigate to Settings, select Support, and then select Device Care. Select Self Diagnosis, and then select Reset Smart Hub.

When resetting Smart Hub, you may be asked to enter the TV's PIN. The default PIN is 0000. If you have ever changed the PIN on your TV, enter your PIN to start the reset.
If this doesn't work, doing a factory reset would be the last troubleshooting step. 
1) Open Settings, and then select General & Privacy.
2) Select Reset, enter your PIN (0000 is the default), and then select Reset.
4) To complete the reset, select OK. Your TV will restart automatically.
5) If these steps don't match your TV, navigate to Settings, select Support, and then select Self Diagnosis. Reset will be located in that menu. You can also check the user manual for exact instructions for your TV model.

If all else fails, the only other option would be service. You would need to call 1-800-726-7864 and ask for TV remote support.

Could you please let me know which channel you watched?

All of them that I have tried so far. Multiple movie channels, but mostly Ion channels and Law and Order channels are what I watch the most. It's basically every channel in the Samsung TV Plus app. Even when my wife is trying to watch 60 days in, or her crime investigation shows. Ironically the app works perfect on my Galaxy S25+, but gets out of sync in my U8000F TV.

Hey, LeadStarDude. I've noticed this lip-sync issue with Samsung TV Plus and Pluto TV often occurs because these apps use a different streaming protocol for their ad-supported "Live" content compared to on-demand apps like Netflix. When the TV switches from the show's stream to the ad's stream, the audio processing can occasionally fall behind.
Have you tried changing the audio format to PCM? Many sync issues are caused by the TV's "Expert" audio processing. Navigate to Settings > All Settings > Sound > Expert Settings > Digital Output Audio Format and change it to PCM. I found broader troubleshooting steps in the link below that might help.

Thank you for this information. I will try it. I had a similar problem with a PS3 years ago where I had to put audio to PCM.

Oh and to be clear I have no external audio devices connected to the TV. This problem is actually with the sound coming through the TV speakers.

Well I tried that and tried adjusting the sound delay in the settings and nothing works. It's crazy how the same apps work perfectly on my Galaxy S25+ phone and on my really old Roku, but are absolute trash on my 2025 year model Samsung TV. ๐Ÿคฆ
