I've been fighting audio sync problems for the past several months. Contacted TWC help, but they pointed me to Samsung...still ticked that I have no "go between" in the way of TWC supporting the app wrt this issue. Samsung always calls me back at a bad time, so I haven't connected with them yet. I have 2014/2015 TVs (such as UN40H6350) and this occurs on all of them. Latest FW installed. Anyone else been having audio sync problems?
It's a Samsung issue... Change to the non CEC hdmi port, if no help, use an Hdmi to DVI cable and a DVI to HDMI adapter to strip off the signal
Which cable box/ DVR do you have?
Rog13kam the Samsung tv app store seems to have a problem with the update date not changing randomly for some apps it seems. I had version 2.10 with the date being 6/30/2015 so I had no idea version 2.82200 existed because the TV never said there was an update until Tier 3 support told me to delete the app and redownload it and all of a sudden 2.82200 appeared but the date didn't change.
I also had the audio sync issue with the "UP" channel, where after a few minutes the audio would just get out of sync. But that was when I was on version 2.10. It stopped happening when I installed version 2.82200.
So to answer your question TWC told me as of a few weeks ago 2.82200 is the latest version.
