Audio/video not in synch on my smart TV.

[adk44]

A couple of weeks ago I finally got my LG smart TV hooked up. But since then, I have noticed that the audio is not in synch with the video on local news shows, ESPN, the Weather Channel, etc. This is not a problem when watching Netflix on the streaming service.

My system consists of my TV, a Sony sound bar, a Samsung blu ray player, and a Samsung HD cable box provided by Time Warner. "Everything" goes into the sound bar and then I have an HDMI cord going from the sound bar to the TV. I have an optical cord doing the same.

I did not have this problem with my dumb TV.

I placed a call to my cable company wondering if my cable box was "modern" enough to handle the smart TV and they said it was.

Any ideas?

Thanks.

Digital TV.
It happens all the time.

All my Digital TVs have done that at one time or another.
Not all the time though, so it I don't think it is the hardware.

No cable company is going to admit it.
Just like when you are in the middle of a football game, and it goes all pixelated.

My TVs and probably most, have a setting to sync voice with picture.
Trouble is, it has never worked on mine, it only goes in one direction, and it is always off in the other direction

Edit
None of mine are, or were smart TVs
