Dear friends- i have found a permanent solution! (No thanks to Samsung #sorrynotsorry) 1. You must use a surge protector with an energy saver control/switch plugs (See picture below) 2. Make sure the Samsung TV is plugged into the control plug 3. Make sure the soundbar is plugged into the switched plug why this works? - the soundbar will only turn on after the TV is turned on. Allowing enough time for the sync up to happen. You may get on occasion the initial both tv speaker/ sound bar on but it resolved itself in seconds. As i indictad in prior post the setting with using direct in optical cable and the power sync setting was not working. I suspected it was that the soundbar was powering on just a bit too early when tv turned on. Anyways please try this and hope it works for you! https://drive.google.com/file/d/11oQkZvmennC3vnlFJSlSIzpnARzaHfhN/view?usp=sharing

Hello same issue here - VERY FRUSTRATING!!! Samsung Q70 connected to Samsung Soundbar via optical cable. Went through all customer-support led troubleshooting. It had a very temporary effect before it returned. My diagnosis. It is the millisecond difference between the soundbar turning on before the TV thus enabling both tv and soundbar speakers. I am going to try using a controlled switch surge protector to fix and will report back here. samsung is no help.
