Audio Is Out of Sync on Your Fire TV Device

To fix issues with audio delay, go to Settings on your Fire TV and use the AV Sync Slider.

For audio delay issues with a Home Theater setup, use Lip Sync Tuning instead.

Note: The AV Sync Slider isn’t available on all Fire TV Smart TVs.

To use the AV Sync Slider:

  1. Go to Settings on your Fire TV.
  2. Select Display & Audio.
  3. Select Audio.
  4. Select AV Sync Tuning.
    When audio and video are in sync, every bounce of the on-screen ball happens at the same time as a flash and a tone.
  5. Make adjustments:
    1. Use the right and left buttons on your Fire TV remote. If the tone happens before the flash appears, move to the right. If the tone happens after the flash appears, move to the left.
    2. Press the Select or OK button on your remote to apply the changes.
    3. Check if the ball, tone, and flash sync up, and make adjustments as needed.
