What To Know About HDMI ARC

HDMI ARC, also known as Audio Return Channel, allows you to send audio from your TV to your AV receiver through the same HDMI cable. That is, it allows you to connect your audio signals to your TV while your TV sends the signal to an audio receiver without the needed of an additional cable. This eliminates the need for separate audio cables and simplifies your setup.

Here’s how it works:

  1. Ensure both your TV and the audio output system (i.e a soundbar) have a functional HDMI ARC.
  2. You connect your TV and your sound system with an HDMI cable that supports ARC.
  3. You connect other audio signal to your TV.
  4. You enable HDMI ARC on both your TV and the sound system.
  5. Your TV can now send audio back to your sound system.

However, your fire TV can encounter problems, sometimes, while connecting to an HDMI ARC. We discuss the main causes below.

Why Fire TV HDMI ARC May Not Work

Here are several reasons why HDMI ARC might not be working on your Fire TV:

  1. Incorrect settings: Both your Fire TV and the sound system need to have HDMI ARC enabled.
  2. Faulty HDMI cable: A damaged or low-quality HDMI cable can disrupt the audio signal.
  3. Software issues: Outdated software on your Fire TV or sound system might cause glitches.
  4. Hardware problems: In rare cases, a hardware issue with your Fire TV, sound system, or HDMI port could be the culprit.

How to Fix Fire TV HDMI ARC Problems

Now that you have a better understanding of the potential causes of HDMI ARC problems in your Fire TV, here are possible ways to fix the issue:

1. Check Settings on Your Fire TV

Sometimes, all you have to do to fix the problem lies in the settings of your Fire TV. That said, do the following to check if the settings is the culprit:

  • On your Fire TV: Go to Settings > Display & Sounds > HDMI/CEC Device Control > ARC/eARC. 
  • Once you get to the ARC/eARC section, make sure HDMI ARC is selected or turned on. This is the common setting for most Fire TV. However, you can consult your TV manual to find the specific settings menu for enabling HDMI ARC. Note that it is usually located under Sound or Audio Output.

2. Find and Verify Your Sound System Connection

To ensure that your TV and the sound system are connected, use the ‘device discovery’ channel to check if your sound system is discoverable by the TV. This tab is usually under the HDMI/CEC device control settings of your Fire TV. Once you click on the ‘device discovery’ tab, it should detect your sound system. If otherwise, check the connection.

3. Ensure the TV speaker is Disabled on the TV Audio setting

To do this, simply click on audio and scroll down to the speaker section. Check to see if it’s set on, and if so, switch it off. This enables you to use only the audio output from the sound system and avoid sound clashes.

4. Verify HDMI Cable

When attempting to connect your Fire TV to a sound system using an HDMI ARC cable, endeavor to use a high-speed cable certified for HDMI ARC. This helps to ensure swift and seamless connection. Nonetheless, it’s important to inspect the HDMI cable for any visible damage when you encounter issues with the connection.

5. Ensure the Sound System Audio Source is Set to TV

Connecting a Fire TV to a sound system using an HDMI ARC cable often goes beyond following the right connection procedures on the TV. Most times, it also involves setting the sound system to HDMI ARC.

Mind you, activating the HDMI ARC on a sound system may vary, depending on make and model. However, if use a soundbar, you can watch out for the HDMI label around the top of the system and use its toggle button to set it as the audio signal source. Otherwise, simply use the system’s remote to activate HDMI ARC as the audio signal source.

6. Check HDMI ARC Port

For the HDMI ARC of your Fire TV to work fine, the port needs to be in a good state. So whenever you encounter connection issues, also ensure you check the HDMI ARC port of both the TV and the sound system. Watch out for any unusual shape or obstruction, which may affect the flow of the connection.

7. Restart the Devices
