Video And Audio Not Synced

I have a problem with my Samsung TV's audio falling out of sync, even with on board apps. A full power cycle by pulling the power cord out and waiting 10 seconds before reconnecting is needed. I didn't know it was a known problem. Any work arounds? I checked and there were no firmware updates available. 

What mode is your TV processing audio?  Since it only has two speakers, it should only be Stereo.

I just checked(Settings>Audio>Expert Settings) and it was outputting Dolby. I changed the input and output to PCM. Now I just have to wait the week or two it takes to happen. I thought it was the TV's memory/buffer becoming overloaded but maybe your onto something. Thanks!

PS. It's a UN43NU6900 if anyone cares.

Pick your poison.  Dolby Digital is highly compressed audio data.  PCM is not compressed.  One requires decompressing and the other storage space.  DD can support up to 5 channels.  PCM can support up to 8.

If you're just listening through your TV speakers (stereo), I'd also check the settings on your streamer to ensure its only negotiating PCM stereo and not DD,

Nothing hooked up to it currently. Running the Android TV interface built into the TV. Except for the random and not too often audio sync problem, I have no complaints. I adjusted the input settings just in case I ever hook up a BR player I have. I will also check the BR player output settings next time I have it hooked up. Hopefully this helps the OP somehow.
