We recently purchased a Vizio 55" smart TV. The sound on it is just terrible. You can barely hear the people speaking because the background noise is so loud. We've tried all the audio settings that are available on the TV , turning off the Surround Sound, turning off the leveling. Nothing helps. BF headed to Best Buy to get a sound bar and was told it wasn't going to help the problem, unless he was willing to get a $700 one where the outside of the sound bar handed the background noises and could be adjusted. Any other suggestions that don't involved spending another $700 on a sound bar. My poor BF is half deaf anyway so it's really a problem.
