Samsung Smart TV HDMI ARC Not Working-12 Solutions To Try Infographic

1. Use High Standard Cables

Begin by ensuring that you are using a certified HDMI cable that meets the HDMI 1.4 standard or higher. The quality of the HDMI cable you use plays a critical role in ensuring a reliable HDMI ARC connection.

HDMI 1.4 standard cables are designed to handle the data transfer and two-way communication required for HDMI ARC.

If you are using an older or low-quality cable it may not support the necessary bandwidth, leading to connectivity problems and audio issues.

2. Check the HDMI Cable for Damage

Take a close look at your HDMI cable. Check it carefully for any physical damage like twists, bends, cuts, or damaged connectors.

If you find any of these issues, it can mess up the signal and cause problems with audio. The fix is usually straightforward: repair it or replace it with a new one.

3. Use the Right HDMI Port

The HDMI ARC functionality depends on using the correct HDMI port. If you are not using the right port, it may result in no audio output.

On both your Samsung Smart TV and your soundbar or home theater system, locate and connect the HDMI cable to the HDMI ARC labeled port.

This specific port is designed to support bidirectional audio communication, enabling sound to flow from the TV to the sound system and vice versa.

4. Remove All External Devices

External devices, like set-top boxes (STBs), gaming consoles, or OTT (Over-the-Top) devices, connected to your TV can sometimes interfere with HDMI ARC functionality.

To isolate the issue, temporarily disconnect all these external devices from your TV. Afterward, try connecting your soundbar or home theater system to the HDMI ARC port and test if audio transmission improves.

If it does, you can gradually reconnect your external devices to identify the one causing the interference.

5. Enable HDMI ARC on Your Devices

Before moving forward with troubleshooting, it’s also important to ensure that HDMI ARC is enabled on your device.

This is important because HDMI ARC isn’t always turned on automatically, and by enabling it, you allow your TV and audio gear to talk to each other effectively.

Enabling HDMI ARC is like making sure both devices can understand each other’s language, so they can send and receive audio seamlessly.

To turn on the HDMI ARC feature:

  • Press the “Settings” button on your Samsung TV remote.
  • Navigate to the “Sound” option.
  • Scroll down to “Expert Settings.”
  • Find “HDMI ARC Mode” and set it to “Auto” or “On.”
  • Press the return or exit button to exit the settings.

6. Enable HDMI-CEC (Anynet+)

Disabling HDMI-CEC, also known as Consumer Electronics Control or “Anynet+,” on your Samsung TV will disrupt the proper functioning of the ARC feature.

HDMI-CEC acts like a conductor, enabling seamless communication between HDMI-connected devices, such as your TV and soundbar.

Keeping HDMI-CEC enabled is essential for the two devices to work together smoothly.

To enable HDMI-CEC:

  1. Press the Home button on your TV remote to access the main menu.
  2. Navigate to the “Settings” option using the arrow buttons on your remote and press OK to select it.
  3. Scroll down to the bottom of the settings menu.
  4. Move to the left to access the sub-menu.
  5. Select “General” and press OK on the remote.
  6. Scroll down again to find “External Device Manager” and click OK.
  7. Inside the “External Device Manager” menu, locate “Anynet+ (HDMI-CEC)” and toggle it to turn it on.

7. Adjust HDMI Sound Delay

Audio sync issues, where the sound lags behind the video, can sometimes happen when using the ARC feature on your Samsung Smart TV.

Samsung provides a useful solution to address this problem with an audio delay adjustment option.

This feature allows you to manually adjust the audio delay to synchronize it with the video, effectively resolving any sync-related issues.

Here’s what to do:

  1. Open the Menu > Support > Self Diagnosis.
  2. Then navigate to Signal Information > Signal History > HDMI Delay Level.

Here experiment with different settings until you achieve the desired alignment between audio and visuals.

8. Ensure the Correct Audio Format

You may be experiencing HDMI ARC problems because your Samsung Smart TV doesn’t support the audio format of the file you’re trying to play.

In such cases, you may need to convert the audio file to a format supported by your TV to ensure proper audio playback and restore HDMI ARC functionality.

9. Restart the Samsung Smart TV

Perform a system restart on your Samsung Smart TV to clear any temporary glitches or software issues that might be affecting the HDMI ARC. So give it a try:

  1. Power off the TV.
  2. Disconnect the TV from the electrical outlet.
  3. Allow a wait time of at least 20-30 seconds before reconnecting the TV to the power source.
  4. Turn the TV back on.

10. Update Your Samsung Smart TV

Outdated firmware can sometimes lead to compatibility problems causing ARC to malfunction so it’s a good idea to check for the updates and If available, install them to ensure your TV is running the latest software.

To check the software updates:

  1. Press the “Menu” or “Source” button on your remote.
  2. Navigate to “Support” in the menu.
  3. Select “Software Update.”
  4. If an update is available, choose “Update Now.”
  5. Wait for the update to finish, and your TV will restart.

11. Reset the Soundbar Settings

If none of the previous steps have successfully resolved the issue, it may be necessary to reset your soundbar to its factory settings. For Samsung soundbars, there are several methods available to perform this reset.

Here are the recommended steps for the Samsung soundbar:

To reset the soundbar using the remote:

  1. Turn off the soundbar.
  2. Press and hold the power button on the Soundbar for about 5 to 10 seconds.

  4. Wait for the soundbar to reboot and restore to its default settings.

2. Alternative Method 1 (Using Remote)

There is an alternative method to reset the soundbar using the remote:

  1. Power off the soundbar.
  2. Press and hold the play or pause button on the remote control for about 5 to 10 seconds.
  3. Release the button when the display on the Soundbar shows “Int” or “Reset.”
  4. Power on the soundbar and try pairing it to your TV again.

3. Reset the Soundbar Without Using the Remote

To reset the soundbar without using the remote you can follow the steps below:

  1. Turn on the soundbar.
  2. Press and hold the volume up and volume down buttons on the soundbar simultaneously for about 5 to 10 seconds.
  3. Release the buttons when the display on the soundbar shows “Int” or “Reset.”
  4. Wait for the soundbar to reboot and restore to its default settings.

12. Reset the Samsung Smart TV

As a last resort, you can reset your Samsung Smart TV to its factory settings. However, be aware that this action will erase all customized settings and data on your TV.

To factory reset a Samsung Smart TV:

  1. Access settings via the “Source” button or the gear icon.
  2. Scroll down to “General” in the settings menu.
  3. Find and select “Reset.” 
  4. Confirm the reset and follow the on-screen instructions.

If you’ve gone through all of these troubleshooting steps and you’re still experiencing problems with your HDMI ARC setup on your Samsung Smart TV, it’s essential to seek further assistance from Samsung’s customer support.
