Samsung TV Keeps Muting Itself [7 Causes And Solutions]

Now, you must have an idea exactly why you have a Samsung TV mute problem out of the blue. But knowing the reasons is not enough alone. You should learn how to figure them out and also, how to fix them.

Remember that identifying the actual cause is the most difficult challenge here. You won’t believe how long it took for me to figure out the issue when it happened for the first time with my TV.

However, once you find out where the issue is, you can easily fix it at your home if there is nothing with the internal parts or hardware.

1. Wrong Network Setting

The most common cause why your Samsung TV keeps muting and unmuting itself is the TV’s connection to the Wi-Fi that isn’t steady. Weak or unstable Wi-Fi can make the TV lose its network link and finally result in muting itself.

If your TV is trying to connect to the wrong Wi-Fi or if the Wi-Fi password isn’t entered correctly, the TV can continue trying to connect. This process will interrupt other operations and the TV will mute and unmute itself.

Again, mistakes in the TV’s network settings, like the DNS or IP address, can mess up the network connection. This struggle can also lead to the TV muting and unmuting.

How To Fix:

If you guess that the problem is with the connection, you should take several steps to fix it. Let’s check what can help to fix this issue:

Strong Wi-Fi Signal

Make sure your Wi-Fi signal is strong. To do this, you might need to move your router closer to the TV. You can even use a Wi-Fi extender to boost the signal for the TV.

Confirm The Right SSID

You have to check your WiFi network connection first. Your TV should be on the right SSID to have the right connection. You can check whether the SSID is right or wrong by following the steps below:

  • Get the TV remote and press the Settings button then tap on the General option and after that select Network.
  • Now, choose Open Network Settings.
  • Find the option for SSID. Tap on it and see whether it is on the correct wireless network name (SSID) or not.
  • If it was wrong you have to select the right SSID.
  • Now, you will check the Wi-Fi Password and if you select a new SSID then input the password in the box.
  • Double-check that you’ve typed the correct Wi-Fi password. If you’re not sure, find it on your router or ask your internet provider for help.

Reset Network Settings

If you suspect network settings are wrong then you should reset the network. For that simply navigate to Settings then press the General option. Now select the Network panel and press on the Reset Network option.

Here, you have to reconnect the TV to Wi-Fi by entering the right network name and password. Make sure to input them properly to avoid further potential errors.

Restart The TV And Router

After any changes, you should restart both the TV and router. It helps refresh the network connection and activate the changes properly.

If you follow these steps properly, you should be able to fix your Samsung TV’s muting and unmuting issue. These tricks once worked for me. Well, if it still doesn’t work, you should contact Samsung Customer Care or your internet provider for more help.

2. Active Dolby Digital

Dolby Digital audio settings issues can also cause Samsung TVs to mute and unmute themselves. When your TV receives a Dolby Digital audio signal from a source like a Blu-ray player or streaming device, it should properly understand and play in high-quality audio format.

If your TV is not set up correctly for Dolby Digital, it can misinterpret the signal. This signal issue might cause the muting and unmuting problem.

How To Fix:

To fix this issue, you should fix the Digital Output Audio format. For that, you can follow the steps below:

  • First, go to your TV’s Settings menu.
  • Then navigate to the Sound settings and then Expert Settings or Advanced Audio Customization.
  • Then find the Digital Output Audio Format setting and press on it.
  • Now you have to choose the correct audio format that matches your TV and audio equipment capabilities. They are Dolby Digital, Dolby Digital Plus, or Dolby Atmos for Dolby Digital audio signals.
  • Your TV will correctly process and play the sound, as you have adjusted the Digital Output Audio Format to match the audio signal.

Just by adjusting the Audio output setting, you can easily solve the sound errors caused by Dolby Digital compatibility issues. On my TV, this feature often caused a lot of issues that’s why I used to keep it turned off.

3. Check HDMI Cables

When a TV from Samsung keeps muting itself repeatedly, the trouble often lies with the HDMI cables. If these cables aren’t working right, it can mess up the TV sound.

A few things can go wrong like loose or damaged cables, or maybe they’re not snug in their spots. When they don’t connect well, it can trigger the TV to mute and unmute without warning. You might even find HDMI cable compatibility issues causing sound problems.

How To Fix:

To tackle this problem, you must follow the steps mentioned below:

Check Connections

You must make sure all your HDMI cables are plugged in correctly and tightly. Sometimes, they wiggle loose and cause sound interruptions. It’s a very common problem and it might be the case for your TV’s sound problem.

Unplug And Replug

If you find everything in fine condition, you should unplug the HDMI cables and then plug them back in. This simple action can often reset things and fix the muting issue. You can even switch places for the HDMI plug heads.

Inspect For Damage

You should examine the cables closely. If you spot any damage, like frayed wires or broken connectors, replace them with new cables. You should get a good quality HDMI cable with industry-standard ratings.

Secure Cable Path

You have to make sure the cables aren’t twisted or bent too sharply, as it can weaken the signal. Also, you should keep them on a smooth path from your TV to your devices.

4. Active A/V Setting

Sometimes, the Samsung TV is on the active A/V settings, and that disrupts the common sound settings. The A/V input of the Samsung TV is responsible for displaying the videos and sound from different sources.

When this input has an issue, it works weirdly. As a result, there can be different video and sound-related issues. In this case, problems like the Samsung sound bar keeps muting can happen at any time.

But I know, how to fix it. Well, it’s nothing but simply adjusting a specific setting on your TV. Let’s see what’s that:

How To Fix:

To solve this issue you have to adjust the A/V support settings. Just go through the following steps for that:

  • Use the remote you have to navigate to the TV’s Home menu.
  • Now, find and press on the Settings menu.
  • After that, You have to choose Sound Settings.
  • Next, look for Speaker Settings or a similar option.
  • In this phase, you have to select Receiver (HDMI) to route audio through your external audio equipment. You will find it in the list of speakers section in the speaker settings.
  • If it’s on the AV setting, you should set it to Receiver (HDMI). It will eliminate any other errors in the signaling process.

It should stop the TV from muting and unmuting, as it won’t struggle with audio output from various sources.

5. Issues With The Sound Card 

The Samsung TV muting and unmuting itself can also be the result of problems with the sound card or the sound amplifier. The sound card is a part inside the TV that handles the sound. If it’s not working correctly, it can lead to this issue.

How To Fix:

There can be different issues with the sound card or amplifier. For those issues, the solutions are different. You can check the following issues on the sound card and fix them as well.

Fix The Loose Connections

If the cables connecting the sound card or amplifier are not properly plugged in, or if the wires are damaged, it can disrupt the sound and cause the TV to mute itself.

In this case, make sure all the cables are securely connected and that there are no damaged wires. This can solve the problem without much hassle.

Reset Sound Card

Sometimes, the sound card has the wrong setting and you need to reset it. Samsung TV Sound Settings is the only thing that can reset the sound card too.

  • At this point, the sound card should work properly.

Replace Faulty Equipment

If the sound card or amplifier is still causing issues, it may need to be replaced. It’s best to consult a qualified technician for diagnosis and repair.

We won’t suggest trying it yourself if you are not a professional. Besides, removing the rear panel of the TV to check the sound card can break the rule of its warranty.

6. Issues With The External Devices

The sound of your Samsung TV can also go mute and unmute when external devices are not connected properly. They can be devices like your game consoles or Blu-ray players. 

If the TV’s connections with those external devices are not secured, your TV can face issues like sound going and coming back. In this case, it’s not actually muting and unmuting, but it simply causes sound to go and come back.

How To Fix:

If your TV is connected to an external device, and you assume that can be the issue, you can fix it by following the steps below:

  • Examine all cables carefully and ensure they are snugly connected to both the TV and the external device. 
  • If cables have loose connections, gently tighten them up. 
  • Try using new or different cables to see if the old ones were the problem.
  • Ensure your external devices have the latest software updates. Outdated software can sometimes cause sound hiccups.
  • If cables are damaged, replace them with new ones.

Besides this issue, Samsung TV can have many different sound problems like it’s being too loud when turned on. If this problem appears, you can fix it with the comprehensive guide on Samsung TV volume loud when turned on we cover this topic.

7. Problem with the Internal Speakers

For the same reason, your Samsung TV mute icon flashing automatically even if you didn’t actually tap on the mute button. I had to suffer a lot from this issue as I was not aware of what to do. Then, a professional technician who was a friend showed me the way to fix it.

How To Fix:
