Hello, As long as your soundbar is connected to your TV via HDMI ARC, you will be able to control the volume and power of your soundbar using your TVs remote. If the feature is not working, or you are not connected via HDMI, you can adjust the remote settings of the soundbar.
This function can be used with IR remote controls only. Bluetooth remote controls (remote controls that require pairing) are not supported. Set the TV speaker to External Speaker to use this function. 1) Turn Off the Soundbar. 2) Push up and hold the WOOFER button for 5 seconds. Each time you push the WOOFER button up and hold it for 5 seconds, the mode switches in the following order: “Samsung-TV Remote” (Default mode), “Off-TV Remote”, “All-TV Remote”. The LED indicator status changes each time the mode is changed. Should you need further assistance, please contact Samsung Support at 1-800-SAMSUNG. ~Samsung Solutions
