No Audio

• Press the "Vol+" button on the remote control that came with the Vizio Sound Bar or in the row of buttons along the top of the device. As you press the "Vol+" button, the second through sixth white squares from the left of the LED screen on the front of the Vizio Sound Bar will start to turn blue, indicating the volume level. If none of those squares were previously blue, the volume was not turned up. Also, press the "Mute" button on the Vizio Sound Bar if the volume lights are blinking to un-mute the Vizio Sound Bar. Alternatively, press the "Input" button on the remote and the Vizio Sound Bar to cycle through the inputs to make sure you are playing audio from the correct input.
