Why is there no sound on my Vizio SB3221n-J6?

  If your Vizio Speaker System has no sound, there are several things you can check: * First, increase the volume and make sure the sound bar isn't muted by pressing VOLUME UP or MUTE on the remote. * Try selecting a different input source by pressing INPUT. * Ensure the volume on your source device is turned up and that the device is not muted. * Some TVs don't pass through digital audio, so try setting the TV output to PCM or connect directly to your Blu-ray player or another source. * Also, set the source to output PCM and confirm that the audio output setting is set to FIXED or STANDARD, not VARIABLE.
