Tried that a several times. I get an follow screen message saying it can't find audio system. But thanks. I ended up returning it for something else. Not because of the sync issue. After experimenting with various streaming sources I'm pretty sure it's the Youtube TV app and not the sound bar. No other source had a sync issue including netflix. I returned it because I wasn't "wowed" by it. It was a very nice sounding bar but I didn't feel the sound platform was as noticeable as I expected or wanted.
