As televisions continue to have larger screens with thinner profiles and sleeker bezels, there is less room for large speakers. To help get the best audio quality out of your VIZIO televisions speakers, we’ve included settings like DTS Studio Sound to provide the highest performance possible, while maintaining the thin, sleek, bezel-less profile of your television. If you’d like any help adjusting your audio settings feel free to contact VIZIO support at 844-254-8087.  For top of the line audio performance, you may also look into purchasing a VIZIO Sound Bar, there are several models available with wireless subwoofers for enhanced bass, rear speakers for true surround sound, and our new line of Atmos Sound Bars. 

Hello Hlruss, sorry to hear that you're having trouble. That's not at all the experience we'd like for our customers. Typically, a lip sync issue can be narrowed down with troubleshooting. If the lip sync is off while watching content on your favorite apps, that indicates that we would want to troubleshoot network connections. Please reach out to our support team on support.VIZIO.com by clicking 'Contact Us'. We'd appreciate the chance to try and help you.
