A:Answer Hi LostInFlyoverState: In all configurations (Optical, Bluetooth, ARC, and Wi-Fi) when the TV is turned ON, the Soundbar will turn ON. If your soundbar is not turning on, it could be due to another reason. For example, if the Soundbar was used to connect to another device (say a smart phone), then it will remember the last device (smart phone) and wait for a command from that device (the smartphone) and ignore the TV ON command.
If you have a Samsung TV, you can adjust the Soundbar’s volume using the IR remote control that came with your Samsung TV. First use the TV menu to set the TV audio on your Samsung TV to external speakers, then use your Samsung remote to control the Soundbar’s volume. ^Patty
