I tried to use my remote to change the volume level, but the remote volume control no longer works at the distance from my chair (10 ft). If I move about 3 ft from the playbar, it works. I changed the batteries twice, but still can not adjust the volume or mute unless I'm about 3 ft from the playbar. Nothing changed (room, furniture. equipment etc). The light on the playbar only flashes when I'm at a close range. The TV (Samsung Smart TV) does show an icon when I press the volume control, but the playbar does not.
I then re-ran the remote control setup. During the process I needed to be close to the playbar in order for the app to recognize the buttons being pressed. After running the remote setup, I still needed to be close to the playbar and could not use the remote from my chair.
