Have you ever been watching something on your Samsung TV only to have the sound suddenly cut off? If so, you’re not alone. 

Suddenly losing sound on your Samsung TV may be shocking, but there’s usually a simple reason behind it. 

TV sound systems can cut out due to user error or a glitch in the TV’s software. Luckily, these issues can usually be fixed in a few minutes, allowing you to return to movie night in no time. 

Why did you lose sound on your Samsung TV? 

Keep reading to find out!

1. Your TV Is Muted

I’ll be the first to admit that I’ve accidentally muted my TV by sitting on my remote. Though this may seem obvious, you could have accidentally muted your TV, leading to the sound suddenly cutting off. 

So, you should check this first before worrying that there’s something seriously wrong with your TV. 

Press your remote’s Mute button and see if your TV begins to play sound again. Alternatively, you can press your remote’s Volume+ button to increase the volume, disabling the Mute feature in the process. 

If your TV continues to remain silent, then it’s time to try out other solutions. 

2. The TV Speaker is Disabled

Your TV may be playing sound through another audio device, like a soundbar or Bluetooth headphones. In some instances, TVs automatically connect to Bluetooth headphones they’ve been previously paired to and start playing sound through them. 

To adjust your TV’s sound output, you’ll need to head to its Sound Settings. 

Let’s learn how! 

Step 1: Press your Samsung smart TV remote’s Home button

Step 2: Use your remote’s Left Arrow button to navigate to the left-hand menu. Then, click on Settings. 

Step 3: Next, head to Sound. 

Step 4: Go to Sound Output

Step 5: Then, select TV Speaker from the different sound output options. 

3. You Must Run a Self-Diagnosis

Running a self-diagnosis on your TV is a good way to figure out where the audio problems may be coming from. Samsung TV support self-diagnosis scans for both audio and HDMI issues.

It’s a good idea to scan for HDMI problems as a faulty HDMI port or cable can cause discrepancies in the audio. 

Samsung TVs have self-diagnosis scans built into their settings, making it easier than ever before to scan your TV for any irregularities.

Let’s learn how!

Step 1: Click the Home button on your TV’s smart remote. 

Step 2: Use the arrow buttons to head to the right side of the screen and select Settings

Step 3: Go to Support

Step 4: Next, head to Self Diagnosis

Step 5: Click on Sound Test

Step 6: Follow any additional on-screen instructions to complete the sound test. If the scan reveals a problem with your TV’s sound, proceed to the next step to fix it. 

If the scan reveals a problem, your TV’s lack of sound could be due to another underlying issue. That said, it’s worth trying the next steps anyway. 

Step 7: Go to your TV’s Settings

Step 8: Head to Sound

Step 9: Open the Expert Settings

Step 10: Click on Reset Sound


In order to complete an HDMI self-diagnosis test, your TV may need to be updated to the latest version. There must also be an HDMI cable plugged into one of your TV’s HDMI ports. 

Please note that some HDMI cables of two meters or longer may produce inaccurate results. So, try connecting a shorter HDMI cable to your TV to ensure the scan’s results are accurate. 

Once you’ve ensured that your TV is set up to deliver the most accurate results possible, follow the steps listed below. 

Step 1: Open your Samsung smart TV’s Settings

Step 2: Navigate to Support.

Step 3: Select Self Diagnosis

Step 4: Open Signal Information

Step 5: Click on HDMI Cable Test

Step 6: Finally, select Start Test

Step 7: If the scan results reveal a problem with the HDMI cable, try reconnecting it to the port and checking that both the cable and port are clear of dust. Also try plugging it into another one of your TV’s HDMI ports, as the one you’re currently using could be faulty. 

If none of the above works, consider replacing your HDMI cable. To ensure future scan results remain accurate, we recommend purchasing one that is shorter than two meters. 

4. Your TV has Pending Updates

Pending updates can cause a variety of problems from lagging to audio issues. You may also have to update your TV’s software to access its HDMI Cable Test scan. 

Not only can updating your TV resolve any audio problems, but it will help ensure your TV is running smoothly and has access to the latest software functions. It will also ensure that your TV’s apps are up to date. 

Some software updates may also resolve any bugs in the previous software’s code. So if you’re noticing that other people with Samsung smart TVs are experiencing a similar problem, it’s a good idea to update your TV as it could be a widespread bug in the OS. 

Many smart TVs update automatically when in standby mode, but if yours doesn’t, you’ll need to check for updates manually. 

Step 1: Head to the Settings. 

Step 2: Navigate to Support

Step 3: Open Software Update

Step 4: If there are any pending updates, click on Update Now. If this option isn’t available, then your TV is updated to the latest version. 

5. The TV Must be Restarted

Even the newest TVs can glitch, leading to audio and video problems. These glitches could have occurred when the TV started up or from a problem with the code or software. 

If the glitches are only temporary, restarting your TV should resolve them. The easiest way to restart your TV is by rebooting the power. 

Let’s learn how! 

Step 1: Turn off your TV and unplug it. Do not simply turn off the power strip. 

Unplug TV core

Step 2: Allow it to be disconnected from power for at least 30 seconds. 

Step 3: Plug your TV into power and turn it on. 

6. The Connected Computer has Driver Issues

Does your Samsung TV’s sound cut off every time you plug your laptop or desktop into it? If so, there could be something wrong with your computer’s graphics drivers. These drivers can cause audio problems when they glitch or have bugs in the software. 

The good news is that updating these drivers will usually resolve the problem. 

Every driver’s manufacturer will have different instructions on how to update their driver. Some of their instructions may also involve installing their app, so it’s best to consult the manufacturer’s directions to ensure you perform this process correctly. 

It’s also important to note that many websites claim to offer driver download links that are actually malware. To avoid installing any sort of virus or spyware onto your device, please only install drivers directly from the manufacturer’s website (even if you may have to pay for them).

Please do not hesitate to contact the manufacturer’s customer service with any questions.

Good luck!
