Please know that you can control the volume of your TV by pressing the +/- button up to increase the volume and down to decrease the volume. To mute the sound, press the button.If the remote is not working at all, please try the following: First, please ensure nothing is blocking the remote from the IR Sensor located below the Samsung Logo at the bottom of your TV. Next, please replace the batteries in your remote. If the remote is working for all other functions but not the volume down button, please use the adjustments below. Let's ensure you are running the latest Firmware version. Go to Settings> Support> Software Update. If you have your sound connected to an external device on your TV, go to Settings > All Settings> Sound > Expert Settings > Digital Audio Output Format > Pass-Through.
