  To resolve the issue of no sound on your Vizio Speaker System: * First, increase the volume using the VOLUME UP button on the remote or the sound bar itself. * Also, ensure that the sound bar is not muted by pressing the MUTE button on the remote. * Try selecting a different input source by pressing INPUT on the remote or the sound bar. * If using digital inputs, set the TV output to PCM or connect directly to your Blu-ray player, as some TVs may not pass through digital audio. For unsupported formats on digital inputs, set the source to output PCM. Also, confirm that your TV's audio output setting is set to FIXED or STANDARD, not VARIABLE. * If you're using Bluetooth, make sure the volume on your source device is turned up and that the device is not muted.
