Found the solution to this when I solved a problem with HDMI AUTO DETECT Try this works for me no the Soundbar does not turn off after 5 minutes anymore: The HDMI Auto Detect feature can be turned off on Samsung 2016/2017 TVs using the remote control by pressing a certain key sequence (either IR or Bluetooth remote works). 1. Make sure TV is updated to latest firmware version 2. Switch TV to TV source – HDMI may not work with BT Smart remotes. TV source works with either remote 3. Using IR Remote: Mute + 7 + 2 + 9 + Exit 4. Using Smart Control: Mute + Vol Down + Ch Down + Mute PLEASE NOTE: TV may or may not display any messages after you press the above key combination. This function is a toggle. So if you want to turn HDMI Auto Detect on again, press the same key sequence.
