A:AnswerHi Chico! You can adjust the HW-A430 Soundbar volume using the TV’s remote control. 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. ^Tim
A:AnswerWhere are those instructions? I'll check and see, becuase I can't get it to sync or work using the remote on either of my older, 2015 Samsung TVs (its either use the remote for volume or don't use it, and there is a lag between TV speaker and this speaker that I can't quite fix with the adjustments on the sound bar).
A:AnswerTo control the volume via the tv you need to use the Bluetooth function. if you are using a cable the only option is to use the volume on the soundbar remote.
