Fire TV Optical Out Not Working

What Is Optical Audio?

Optical audio, also known as Toslink or SPDIF, is a type of digital audio connection. It uses pulses of light to transmit audio signals, providing a clean and interference-free way to send audio from one device to another. In the context of Fire TV, the optical out is a handy port allowing you to connect your device to a sound system or soundbar.

Possible Reasons Your Fire TV Optical Output Is not Working

Optical audio issues on a Fire TV can be frustrating, but figuring out the cause can help you fix the problem and get back to enjoying your content. Here are some common reasons your Fire TV optical out is not working:

  • Faulty Physical Connections
  • Wrong Audio Settings
  • Software Issues

How To Fix Fire TV Optical Audio Issues

You can fix the optical audio issues on your Fire TV through the following means:

1. Check Your Hardware Connections

First things first, let’s make sure everything is plugged in where it should be. A very common factor that causes the optical audio of a Fire TV to not work is loose/damaged cables, wrong input selection, and dusty/obstructed cable ports.

Here are things you can do to fix this:

  • Inspect Optical Cable: Since the cable is integral to a smooth connection between audio sources and the TV, any fault in the cable may affect the audio performances of the TV. So, check to see whether a faulty cable might need replacement. If it’s fine, ensure the optical cable is securely connected to both the Fire TV and your audio device. Sometimes a loose connection can be the root of the problem.
  • Verify Power: Confirm that both your Fire TV and the audio device are powered on. It’s a basic step, but sometimes the simplest solutions are the most effective.

Additional Tips To Prevent Fire TV Optical Output Issues

You might also want to consider the tips below to ensure that the optical output of your Fire TV works fine:

  • Try using a different optical cable. Some cables are of lower quality and can cause issues.
  • If you’re using a soundbar, consult its manual for specific troubleshooting steps related to optical audio input.
  • Consider using an HDMI connection instead of optical. HDMI can carry both audio and video in a single cable and often offers higher quality.

2. Navigate Fire TV Audio Settings

Now is the time to explore the settings on your Fire TV and make sure everything is configured correctly. Follow the guide below to do so.

  • Access Fire TV Settings: Using your remote, go to the settings menu on the TV. You can simply press the settings (gear) icon on the remote and wait for the TV to respond almost immediately.
  • Select Display & Sound: Navigate to the “Display & Sound” section. From there, choose “Audio.”
  • Check the “Optical Audio Format”: Choose “PCM” for uncompressed audio or “Dolby Digital” for surround sound compatibility.
  • Regulate Audio Sync Tuning: If audio and video are out of sync, adjust the “AV Sync Tuning” slider in the same settings menu.

Tip: Experiment with different audio settings to find the configuration that works best for your setup.

3. Inspect Your Audio System

It’s important to check the TV’s audio system. Here are the things you need to do at this point:

  • Check Audio System Input: Ensure that the optical input on your sound system or soundbar is set to the correct source. It’s possible that the device is waiting for input from a different source.
  • Test with Another Device: If available, try connecting another audio source to your sound system using the same optical cable. This will help determine if the issue lies with the Fire TV or the audio system.

Additionally, you can ensure that the optical input on your sound system or soundbar is set to the correct source by following the tips below.

On your sound system or soundbar:

  • Locate the input buttons: Look for buttons, knobs, or on-screen menus labeled “Input,” “Source,” “Digital,” or something similar. Some devices might have dedicated buttons for individual optical inputs.
  • Cycle through the options: Use the buttons or on-screen controls to cycle through the available input sources. You might see labels like “Optical 1,” “Optical 2,” “S/PDIF,” or simply “Digital.”
  • Match the input to the connection: Remember which optical port you connected your Fire TV to (e.g., Optical 1). Select the corresponding input on your sound system or soundbar.
  • Verify with the display: Many devices display the currently selected input on the front panel or on-screen. Look for confirmation that the correct input (e.g., “Optical 1”) is chosen.

4. Update Fire TV Firmware

Outdated software can sometimes lead to compatibility issues. SO, you might also want to update your Fire TV to the latest firmware versions. They often contain bug fixes that may address audio issues. Here’s how you can ensure your Fire TV is up to date:

  • Navigate to Device Preferences: In your Fire TV settings, go to “Device Preferences.”
  • Select About: Choose “About” and then “Check for System Update.” If an update is available, go ahead and install it.

5. Reset Fire TV Audio Settings

When all else fails, a good old reset might do the trick. To reset the audio settings of your Fire TV, go back to the “Audio” settings of the TV. Look for an option to reset audio settings to default. This will revert any custom configurations you’ve made.
