      I have an Amazon fire TV cube. When I first got it, I had no problem with it. Now after a few minutes of watching any program (whether on Amazon Prime Video, Disney+, Acorn, Hulu, Netflix or whatever) the sound becomes unsynced. I have tried rebooting it and it doesn’t fix it. I have searched the web for fixes and don’t find anything that solves the problem. I end up switching over to my Vizio TV smartcast page and watching from there. I liked the Amazon cube when I first got it but am ready to crush it with a hammer now. Any ideas on how to fix this?

      Hello Deane,

      Few things you can try, first off make sure you are properly powering the device along with making sure its is updated.

      If you are experiencing this problem, please make sure that your firmware is up to date. We know that using the TV USB port to power the Fire TV will drop frame rates which can cause audio sync issues so please use the main power supply.

      Home Theater Audio is Out of Sync
      Turn on your Fire TV device.
      Select Settings from the home screen.
      Select Display & Settings.
      Select Home Theater Settings.
      Select Lip Sync Tuning.
      Follow the on-screen instructions to synchronize your audio and video.

      If using a sound bar / surround sound.
      First, if you are running your sound through a sound bar or sound system, turn the TV speakers OFF via the Vizio remote, Menu > Audio. Also in the Audio menu, find the Lip Sync adjustment. It will probably be on 0.0 with settings from 0.0-5.0. Put the setting at 2.5, save your settings and exit.

      How is your device wired to your TV is it directly connected or routing through anther device?

      I am using the power supply that came with the cube and I have an hdmi cable running directly from the cube to the TV.

      Hello Deane,

      I found a support page with some recommendations from Vizio, then they state if the solution of changing the audio out type on the TV to PCM then you will need to contact Vizio directly.

      Contacting Vizio support.
