Why does my Samsung TV have no sound?

Your Samsung TV have no sound because it’s muted, has zero volume, connected to an external speaker, and has its built-in speaker turned off. Loose or faulty cable connection, software glitches, outdated TV and device software, and mechanical damages also cause your Samsung TV to not produce sounds.

No sound on Samsung TV: 9 causes & ways to fix the audio

#1: Muted TV

“My Samsung TV doesn’t play any sound even if I change channels.”

Have you already checked whether the TV is muted?

It sounds like a very simple problem, right? But it can be easily overlooked by users.

If you’re using a remote to navigate your TV, it’s so easy for anyone to accidentally press the “mute” button.

Once pressed, a “mute” icon will appear on the TV for barely a second. 

So, it’s possible for you to not notice it.

When a Samsung TV is muted, no sound will play. Unless you disable it.

How to fix it:

Play any video on your Samsung TV. And get your TV remote.

Look for the mute button on your remote. 

Most Samsung TV remotes have their mute button positioned at the center.

Plus, it has a “mute” label on the button. So, you shouldn’t have a problem finding it.

Once you’ve found the mute button, press it once.

After that, the audio of your Samsung TV should now be fixed.

Note: You can also disable the mute function by navigating the TV’s settings. But that takes more time than simply pressing the mute button on the remote.

#2: Volume set to zero

If it’s not muted, your speaker volume might have been set to zero.

Again, it’s a simple issue. But many users often overlook it.

When the audio volume is set to zero, you won’t hear anything from your TV.

If it’s not set to zero, the audio volume must be really low. Making it appear that your Samsung TV has no sound.

How to fix it:

If your Samsung TV has no audio, try pressing the volume-up button. This should easily resolve the audio issues with your device.

Still doesn’t work?

Then your TV’s audio input must be set to an external device.

If that’s the case, you should increase the external device’s volume.

Suppose you’re using a soundbar. Use your soundbar remote to turn on or increase the volume of your Samsung TV.

If that doesn’t work, try the other troubleshooting steps below.

#3: TV connected to an external speaker

Do you often connect your TV to an external speaker?

Have you recently used headphones with your Samsung TV?

If yes, then that must be the reason why.

When an external speaker is connected to a TV, the sound output will switch to the external device.

If you can’t hear anything from your TV, the audio may be playing on your external speaker or headphone.

So, technically, your Samsung TV isn’t silent. 

It’s just that the audio is playing on the other device. Making it appear that your TV has no sound.

How to fix it:

If your Samsung TV is connected to a headphone, you must disconnect it.

Here’s how to disconnect an external speaker with the Samsung TV:

  1. Go to the TV’s settings.
  2. Select “Sound.”
  3. Choose “Sound Output.”
  4. Click “Bluetooth Speaker List.”
  5. Select the device you want to disconnect.
  6. Then, tap “Disconnect.”

Tip: Play music or video before doing this process. That way, you can check right away if the process has worked. And don’t forget to volume up the audio as well.

#4: TV internal speaker disabled

“The video is playing perfectly on my Samsung TV. But I can’t hear any sound…”

If that’s the case, maybe your TV’s internal speaker has been disabled.

Samsung TVs allow you to change your audio output. 

You can switch the audio output to your external device if you want to. 

The problem happens when you’ve removed the external device. And you didn’t change the audio output on your TV.

When that happens, the internal speaker of your Samsung TV will continue to not play any sounds.

How to fix it:

To resolve this audio issue, change the audio output on your Samsung TV.

Make sure that the TV internal speaker is enabled.

Here’s how to enable the Samsung TV internal speaker:

  1. Go to the TV’s settings.
  2. Select “Sound.”
  3. Click “TV Speaker.”
  4. Then, toggle on the “TV Speaker” switch.

After this, your TV internal speaker should work again.

Tip: Press the “Menu” button on your TV remote to quickly access the settings page.

#5: Loose connection with the external device

Do you use a streaming device with your Samsung TV?

If yes, check the condition of the cable that connects the devices.

Loose connections can affect the audio output of your connected streaming device. Making your Samsung TV silent.

If your TV isn’t playing any sounds, then it’s possible that the:

  • Cable is faulty or damaged.
  • TV cable port is loose or completely broken.
  • Cable is not properly connected with the devices.

These cause an unstable connection between your Samsung TV and the connected device.

Without a stable connection, it would be hard for the devices to exchange signals and data. 

As a result, your Samsung TV may fail to produce any sounds.

How to fix it:

First, make sure that the cable is connected to both ends.

If that doesn’t change anything, assess the cable for any damages. Look for any signs of:

  • Bite marks.
  • Poorly-bent wire.
  • Exposed wirings.
  • Burnt areas on the edges.

If you notice any of these on your cable, replace the cable as soon as possible.

It’s also possible that the TV cable port is faulty. So make sure to check on it as well.

Follow this instruction to test the condition of your TV cable port:

  1. Remove the cable from the port.
  2. Then, reinsert the cable to another available port.

When you can’t hear sounds even after doing step #2, your previous port is faulty.

You may also reinsert the cable to the previous port to confirm its condition.

#6: Faulty HDMI cable

Faulty HDMI Cable

Are you using an external device that connects via HDMI cable?

If yes, then its connection may be what causes the problem.

Dropouts due to loose connections can happen with HDMI-connected devices as well.

When the HDMI cable is faulty, your Samsung TV may not produce any sounds.

If not the cable, then the HDMI port must be the issue.

Regardless of which, a stable connection is needed to resolve the audio problem.

How to fix it:

First, check if there are visible damages on the HDMI cable.

If there’s none, you may proceed with the HDMI cable test.

Some Samsung TVs have an HDMI cable test. This allows users to assess the condition and connection of their HDMI cables.

If you’re using an HDMI-connected device, doing this test would be helpful.

Here are some important things you should know about the HDMI cable test:

  • Only some Samsung TVs have this function.
  • This process only works for devices that have video signals.
  • It works only with HDMI cables that are less than 6.5 ft (2 m) long.

Does the HDMI cable test apply to your Samsung TV? If not, then skip this step.

To do the HDMI cable test on a Samsung TV:

  1. Keep the external device connected to your TV.
  2. Go to the TV’s settings.
  3. Select “Support.”
  4. Click “Self Diagnosis.”
  5. Tap “Signal Information.”
  6. Then, press “Start Test.”

This test will tell you whether there are problems with your HDMI cable. 

Take it as a guide whether you have to get an HDMI cable replacement.

#7: Software glitches

Your Samsung TV is a “smart TV.” 

Meaning it connects to the WiFi to work. And so, it has software to function.

Since a Samsung TV has software, it’s prone to software bugs and system glitches. These things can affect the settings of your TV if not resolved.

They disrupt the connection of your TV. Which may cause it to not respond to commands or activate certain functions.

And yes, software bugs and glitches can significantly affect your TV as well.

So, if your Samsung TV isn’t playing any sounds…

Then your TV must be experiencing some software glitches.

How to fix it:

Software glitches sound too technical, don’t they?

But resolving it is super easy! So, no need to worry about being a non-techie person.

To resolve the problem, you just have to soft reset your Samsung TV.

Note: Soft resetting is simply refreshing your TV’s system. And it doesn’t delete any data.

Here’s how to soft reset a Samsung TV:

  1. Unplug your TV without turning off its power.
  2. Wait for at least 5 minutes.
  3. Replug your Samsung TV.
  4. Power on the TV.
  5. Then, check whether the sounds work.

“I’ve already checked the cables. But my Samsung TV still have no sound!”

If that’s the case, perhaps your TV software is outdated.

Bonus: Hardware damage

“I’ve tried everything already. But nothing worked!”

Perhaps your Samsung TV have hardware damage.
