Step 2: Try connecting your audio system to another device to see if there’s a delay. 

Solution 4: Perform a Power Cycle

A power cycle is also known as rebooting or restarting your device. This has been known to remedy many existing issues with a smart TV, including audio lagging. 

  • Power off all your devices including your smart TV and the streaming device. 
  •  Unplug the device from your TV 
  •  Unplug the power adapter from the power outlet and leave it as is for a couple of minutes
