Nope. Very disappointing service from Samsung on this issue. I just used an optical instead of HDMI, so I gave up Dolby Atmos so I could get lip sync. Not a happy customer.
I just purchased this soundbar and have the same issue. Video is ahead of audio. Was thinking maybe I can slow the video feed on the TV (a TCL). Let me know if you figure out a solution.
I bought an optical switcher on Amazon.
Now I am running an optical direct from the switch with a single out to the soundbar.
No delays, but needed extra equipment but more importantly unable to transmit in Dolby Atmos which is the whole point of buying this soundbar. Extremely disappointed that Samsung has not fixed this issue, this is pretty much false advertising.
