Just installed the above sound system. Great except that the sync of the voice to the movement of the mouth is not correct and the voice is lagging. Suggestions? TV = QLED QE55Q85R - connection using HDMI ARC to ARC from the Samsung console to the soundbar. Thank you
@brucewm: Please try pressing the Sound Control button on the soundbar remote repeatedly until 'Sync' is displayed, then use the Up/Down buttons to set the audio delay between 0-300 milliseconds. Are you able to sync the audio and video in this manner?
On my Panasonic frame tv I go to settings -> sound -> expert Mode > Digital output Audio Format -> Auto
I think what is happening is the tv is trying to decode the audio then send to sound bar causing audio delay. In pass-through the sound bar will do the decoding I think with no delay.
Look at these instructions says to set to by-pass for earc
