Note: The steps to adjust the following settings vary by TV brand and model. Check your TV's user manual or online support pages for more information.

To get started, check these device settings:

  • Confirm that your TV supports HDMI ARC.
  • Turn on the HDMI ARC setting on your TV. Use the remote that came with your TV and go to the settings on your device. You can also find steps for some common TV brands on Manage the HDMI ARC or HDMI CEC Setting on Your TV.
  • If you have a sound bar or A/V receiver, unplug it from the HDMI port on your TV.

  • Plug your Fire TV device into the HDMI port labeled "ARC" on your TV. If you have another device connected to that port, move it to a different HDMI port.
