How Do I Get The Sound Back On My Vizio TV?

When the sound goes out on your Vizio TV, it can get frustrating. It often happens when you are in the middle of one of your favorite shows, which can leave you scrambling to get the sound back. 

Turning it back on for your TV does not need to be difficult. Some of the steps include:

1. Check The Volume

Sometimes the remote will set the volume down at zero. You need to check to see if this is the problem or not. 

Simply click the up and down buttons on the remote to see where the sound is. This helps you figure out if the volume is muted or at zero and is a simple way to fix the process. 

Try turning the volume up on the TV and not the remote.

If you have a Cable or Satellite box, make sure that the audio is turned up and not muted within that box.

2. Check The TV Speakers

Once you have checked the volume and made sure it was not at zero or mute, it is time to check the speakers. You want them to be on, not auto.

The steps to check this include:

1. Using the Vizio remote, you will press the Menu button. 
2. Use the arrow keys to help you highlight Audio Settings or Audio. Click OK. 
3. Make sure that next to the setting for TV speakers, the button “on” is pressed. If it says the speakers are off or on auto, choose “On” to fix this. 

3. Check The Connecting Cables

When the cables are not securely connected, you may not be able to hear the right sounds from the TV. 

To check on this, simply disconnect and then reconnect the cables into the back of the TV. Check that you are putting them in the right spots and getting them securely into the TV so you can hear. 

While you reconnect the cables, take a look at them. If any look like they have been cut or frayed, this could be the problem. When this happens, it is time to replace them. 

4. Unplug your Cable Box

This is a simple thing to try, simply unplug your cable box and plug it back in. See if it did the trick. You can also try turning it on and off.

5. Try A New Source Device

If you turn on the TV and struggle to get any audio from the satellite or cable box, you may want to switch the inputs to another device. This could be your streaming device or another gaming system. 

If your TV is connected, you can try to play audio from one of your other apps. YouTube is a good one to test out for this. 

If you use a soundbar or any other external device, disconnect them and use the TV speakers to test the sound. You can do the same if you have a streaming stick like Amazon Firestick. Hook it up to your TV and see if it will get any sound.

If your external device works but the cable box doesn’t, it can be an issue with the HDMI port or the cable box settings. Try plugging your cable box into the same port as your external streaming device and see if gets the sound.

6. Disconnect all unnecessary devices

If you have any other devices connected to your TV, make sure to disconnect all of them to see if they were causing the issue. Also, avoid using the power strip, plug your TV directly into the wall instead.

7. Check for Updates

Sometimes the issue can be caused by your TV missing some important update for some reason. We have a detailed article on how you can update your VIZIO TV and see if it will help with the sound.

8. Power Cycle your TV

This is a simple, yet quite an effective way to fix some of the software glitches that your TV might have had.

• Turn the TV off.
• Unplug your TV from the wall.
• Press and hold the “Power” button on the side of the TV for 5 seconds(or on the remote).
• Plug the TV back in.
• Power the TV back on.

9. Factory Reset your TV

If the power cycling method didn’t work for you, let’s try to factory reset your TV next. It will erase all stored data and delete all the information. This will also reset all the audio to factory settings, which can help us with this issue a lot.

• ​​​​​​​Press the Menu button on your remote.
• Go to System > Reset & Admin > Reset to Factory Settings
• Once the Reset is complete follow the on-screen setup instructions.

10. Look At The TV Warranty

For those who have tried all of the other options and have not been able to get the audio to turn back on, it is possible that the TV is to blame. 

If you put a warranty on the TV, you should visit the Vizio website to request warranty service and get the issue checked out. You can still get the TV looked at without a warranty, but you should shop around to see what the best price is. You can also contact VIZIO support.

Looks like a lot of VIZIO TV users are having these sound issues because of the defective main board of the TV. There is not much you can do yourself, it’s best to contact the technicians.

Why Does My Vizio TV Keep Losing Sound?

For the most part, the steps above will help get the sound back on this TV and ensure you can enjoy the video you want to watch. 

For some people, though, the sound on the Vizio TV may seem like it goes up or down on its own. This can sometimes be a conflict between the device or the program that you want to watch and the advanced audio settings for this TV. 

You can turn this off to avoid problems with not being able to hear. The steps include:

1. Head to the Main Menu on the TV. 
2. Go to Audio Settings and then Advanced Audio. 
3. Click to turn off the SRS TruVolume.

You can also turn any of the audio leveling options off from the other devices that you have. For a satellite or cable box, you can change the audio setting from HDMI Auto to HDMI Fixed to help. 

The Background Noise Is Louder Than The Talking

Sometimes the audio may be loud enough, but there is a lot of background noise. This will make it hard to hear the people talking in the show. 

This is a problem with the SRS TruSurround feature on this TV. To turn it off, you can:

1. Get into the Main Menu and then the Audio Settings. 
2. Go into Advanced Audio.
3. Turn off the SRS TruSurround.

This will help get the volume balanced back out so you can hear everything going on in the show. 

Volume Is Low Even When Turned Up

If you are working with a satellite or cable box, this can sometimes mess with the sound you hear. Check the internal audio settings on those to see if you can increase the volume. 

This can fix most issues. If the sound is still there, it is time to go into the TV itself to fix it. 

You can do this through the Main Menu and entering the Audio Settings. Turn off both SRS TruVolume and SRS TruSurround to see if these fix the problem. Check out the list of the Best Streaming Devices on Amazon now!

It is always good to have a troubleshooting checklist before any issue is escalated.

I personally have faced several volume-related issues on my Vizio TV. Keeping this in mind, I have made a checklist for resolving the issue.

A few weeks ago, I wanted to watch a very important football match. I had been waiting the entire day to watch it after work.

But as soon as I turned my Vizio TV on, I was terribly annoyed to find that there was no audio on my TV.

From my past experiences, I have realized that having an audio-related issue does not necessarily mean that there is some technical issue with the TV.

There can be very obvious causes, like your TV being on mute. Sometimes, the audio output device is connected to the 3.5 mm jack without you knowing.

To create this checklist, I thoroughly went through the audio options on my Vizio TV and watched some very useful youtube videos to understand the basics of audio transmission on Vizio TVs.

I also went through the FAQs available online to understand the audio issues that are most frequently faced by Vizio TV users. I am sure that this checklist would be helpful for you as well.

To fix the volume on your Vizio TV, make sure your TV is not on mute, check if the remote control is working properly, check the HDMI cable, and make sure that the satellite box is not on mute.

This troubleshooting checklist below will solve audio issues on your Vizio TV in most cases.

Check if your Remote Control Works

Sometimes, due to dead batteries or other issues, Vizio TV remotes stop working properly.

That may very well be the case with you if you are facing issues with your TV volume.

It is therefore always a good idea to start troubleshooting by checking if your remote is working properly.

Turn on your TV and press the volume functions on your remote. If the TV is not responding to the remote control then try replacing the battery in the remote.

If changing batteries does not work then unfortunately it is time to get a new remote.

Move to the next step if you find that the remote control is working properly.

Ensure your Vizio TV is not Muted

You may absent-mindedly have put your Vizio TV on mute. If that is the case, you will not hear any audio from the TV if that is the case.

Try unmuting your Vizio TV by pressing the mute button on the Vizio remote.

Checking the Vizio TV Volume may help if your TV is not on mute.

Check your Vizio TV Volume

So you have pressed the mute button but you still cannot hear anything. It may be the case that your TV volume has been set to zero.

Use your TV remote and press the ‘+’ side of the volume button.

Make sure that the TV volume is adjusted to an audible level above zero.

If the TV volume is adjusted properly but you still cannot hear anything then checking your HDMI cable may help.

Check your HDMI Cable

HDMI cables play a very important role in transmitting audio and video signals to the TV.

Your Vizio TV may face volume issues if the HDMI cable that connects your TV to an external device is faulty.

If you can see video on your TV but there is no audio then it is very much possible that your HDMI cable is broken.

You can try using a different HDMI cable to check if the audio issue gets sorted.

If the audio issues get sorted upon using another cable, this means that the previous HDMI cable you were using was faulty. 

Check the Volume Settings on your Set-Top Box

Audio and video signals are transmitted to the TV through the set-top box if you are using a set-top box.

Therefore, it is important to check the volume setting on your set-top box if you are facing audio issues.

Use the remote to first make sure that the set-top box is not on mute. After that, use the remote to increase the volume to audible levels above zero.

If this does not work then move to the next step.

Check if SAP has been Enabled on your Vizio TV

SAP, short for Secondary Audio Programming, is used to listen to the video on the TV in a language other than the original language.

It is usually a second audio stream that is included in the TV show.

SAP can be turned off on your TV if you wish to watch the show in the original language. ‘SAP’, ‘Audio Select’, ‘B-Audio’, ‘MTS’ etc are all popular menu labels for SAP.

Follow these steps to ensure that SAP is enabled on your Vizio TV:

• Press the ‘menu’ button on your TV remote.
• Select the ‘Audio’ option from the list of available options.
• Select the ‘SAP’ Option.
• Select the desired setting.

Turning off DTS TruSurround on your Vizio TV may also help if issues persist.

Turn Off DTS TruSurround on your Vizio TV

A lot of Vizio TV users face volume issues because of the TV’s advanced audio settings.

A conflict between the program you are watching and DTS TruSurround may be causing audio issues with your Vizio TV.

Turning off the advanced setting may help in such a situation. To turn off DTS TruSurround on your Vizio TV, follow these steps:

• Go to Main Menu.
• Go to Audio Settings.
• Go to Advanced Audio.
• Turn off DTS TruSurround.

If this does not work, move to the next step.

Check if a 3.5mm Audio Cable has been Plugged in

Your Vizio TV speakers will not transmit any audio if any device has been left plugged into the audio jack of the TV.

It is possible that a device such as an earphone or a headphone has been left plugged in from before.

The TV would send audio output to the connected device if this is the case.

Audio output on these devices would obviously not be audible if you are not wearing them.

Disconnect the device and then try increasing the volume on the TV.

Resetting your Vizio TV might help if no device is connected to the audio port.

Reset your Vizio TV

If none of the above ways have worked to resolve your audio issues then resetting your Vizio TV would most likely set it right.

• Press the ‘menu’ button on your Vizio remote.
• Navigate to and select the ‘System’ option, using your remote.
• Navigate to and select the ‘Reset & Admin’ option.
• Select ‘OK’
• Put the parental code, if you have manually put one.
• If you have not manually put any parental code then put ‘0000’ as the password when asked for.
• Select the ‘Reset’ option.
• Press ‘OK’
• Wait till the TV turns off.

After a while, the TV will turn on again and the Setup App process would begin.

Contact Support

It may be possible that none of the above work and you are still facing audio issues.

In such a case, you must escalate the issue and seek help from the Vizio customer support team.

You can find the relevant customer care information on the Vizio Support website.

Conclusion

You would know by now that there can be numerous reasons why you are facing audio issues on your Vizio TV.

These reasons range from slightly technical things such as advanced audio settings to very simple and straightforward things such as low volume or a 3.5mm jack plugged in.

Now that you have read this article, you would be able to check your TV for both simple as well as relatively technical problems.

This would solve your audio issues in most cases and help you get your audio back quickly. I hope this helps.
