Do Some Platforms Have A Higher Propensity For Audio Sync Problems? 

The bandwidth of your internet may affect streaming services and casting equipment. Your display’s graphics may need a higher quality and a delay in other audiovisual transmissions if your internet connection is too slow to support multi-screen streaming. Audiovisual transmission is more dependable over wired connections; however, avoid using counterfeit wires because they could damage the internal hardware of your device.

  • Try switching channels or using a different streaming service to see if the problem persists. When utilizing a Smartcast TV, you can switch from your streaming device to the TV’s smartcast mode, select a channel, and wait for it to play for roughly a minute.
  • Your streaming device or app should now be the TV’s new input, and the audio should sync with the video.
  • Use your Vizio remote control to mute your TV speakers if a sound system is connected to your Vizio smart TV.

Audio settings

  1. Using the TV remote, choose “Menu.”
  2. From the menu that appears, pick “Audio.”
  3. Find the “Lip Sync Adjustment” option and select it. From 0.0 to 5.0 are the available parameters. It is most likely currently on 0.0.
  4. Change it to 2.5, save your selection, and click “Exit.” While off, unplug none of the linked gadgets, including your smart TV.
  5. The issue with your lip-syncing should be resolved if you switch them back on.
