Vizio TV Sound Not Working / No Sound [SOLVED]

The Vizio TV sound not working is one of the most common problems with Vizio TVs. Here you will find a step by step troubleshooting guide that fixes the problem on most Vizio TVs.

Vizio is a well-known brand in the Smart TV and sound system industry. In fact, Vizio products are among the most popular ones on the market today. The reason why they are so successful is that they produce top-quality products at affordable prices. Unfortunately, like with any other electronic equipment, Vizio TVs have the tendency to fail or have issues.

When you’ve got a Vizio TV and audio settings that conflict, your volume may fluctuate. It’s possibly caused by a firmware bug, a failing cable, or something wrong with the TV’s output settings. If you’ve got a remote that doesn’t seem to be working, try unpairing it and pairing again.

We will suggest you with several tips on how to deal with Vizio TV No sound problems.

Vizio TV Sound Not Working – Troubleshoot And Diagnosis

There are several reasons why you may not hear sounds on your Vizio TV. It could be that you have the volume on mute, there is a problem with the input function or bad cable wiring. The latest version of software from Vizio is required — when update it your system may start working perfectly again.

1. Do A Power Cycle

If your Vizio TV sound isn’t working, it’s possible that there is a simple fix you can make. If you disconnect the TV from the wall and let it sit for 60 full seconds without being plugged in, the reset should bring your Vizio TV back to working order.

If your Vizio TV sound is not working, try unplugging it for a full minute. It might be tempting to just quickly try to unplug it and plug it back in immediately, but waiting the full minute is important for two reasons:

First, it gives the speakers a chance to cool down. You want to avoid frying any sensitive circuitry. The 60-second timeframe also gives the TV enough time to properly power down and release all electricity before you plug it back in.

The first step to fix this problem is to unplug the power cord. Unplugging it will cause the TV to “soft reset” and will hopefully solve the problem. If this doesn’t fix the problems, wait five minutes and plug it back in. This should be enough time for the TV to turn on and start working properly.

80% of the time, this fix should work. If you’re still having trouble, try the fixes detailed below.

2. Check Current Sound Source

Are you sure the no sound problem with your Vizio TV is coming from the TV itself and not from the channel? If there is no sound on channels like ESPN and FX, you should check your cable settings.

Cable channels often have a problem with the audio, so if this problem isn’t affecting your other devices (like Blu-ray players or PlayStation), then you should definitely check out your cable box.

Of course, you could also switch to a Watch TV source to see whether the problem is coming from the device your using to play content on your TV. If it’s the device you’re using to send content to the TV, make sure to restart the source and test again.

3. Check TV Volume

It’s a fact that, even when you’re not doing it intentionally, you might accidentally turn off the volume of your Vizio TV. But all is not lost!
Here are four ways to fix this problem and make your TV sound like it’s supposed to:

Turn on the Mute button on your remote control.

Adjust the TV’s volume from the panel on the front of the set.

Vizio has a very easy-to-follow press-and-look process to determine if your TV is muted or not. Press the mute button on your remote. If a highlighted icon appears on the bottom left of your screen, then yes — your TV is muted. If you just pressed the mute button and this is the first time you’re pressing it today, then definitely check into it further.

4. Check Cable Connections

If you experience static sound on your Vizio TV, check that all the cables are properly connected and functional.

In particular, ensure that the audio cable is securely plugged into both the TV and the audio output device, such as an HDTV or home theater receiver.

If you’re using a third-party device to listen to TV sound, make sure it’s fully functional as well.

It’s possible that a loose or unplugged cable is causing interference. This can make it so you can’t hear the sound from your TV, which is obviously undesirable. Just ensure that all the cables are plugged in and functional. A third-party device like an audio receiver might cause interference, so double-check those as well.

To avoid problems, be sure to set up your TV cables correctly. If one is too long or if it’s under any kind of strain, the video impurity may degrade to unbearable levels.

After you plug in your TV, don’t subdue your picture by adjusting the volume. Instead, adjust your audio settings through the menu on your remote.

5. Check Audio Input Settings

Sometimes, you accidentally change the audio input on your TV, whether you or someone else uses the remote during a spontaneous moment.

To be specific, there is a small button on the remote that allows you to change the audio input. But sometimes, nobody has anything connected to your TV. When this happens, there will be no sound on the screen until you change it back.

For Example, If anyone presses the AUX button on your Vizio smart television remote, the audio input will be set to “AUX.” But since there is no device connected of this kind, the TV will stop producing audio, and only display the yellow “Audio In” message on the bottom right corner of the screen.

Here are the steps on How to change Audio input settings on Vizio TV.

If you’re not familiar enough with your Vizio TV to find the button for input, find the “INPUT” button on your TV remote. Press it once, and then select “Soundbar” if you have a soundbar connected to your TV, or “DEFAULT” if you’re using the TV speakers.

6. Remove Any Interference

If the sound on your Vizio TV isn’t working, check to make sure that you’re selecting the right audio input. If the issue persists, try disconnecting all of the devices that are connected to your TV. Then, try watching a show or movie to see if the sound works.

If your Vizio TV is set to the default speaker mode and you still can’t hear the sound, then there is a chance that a 3rd party device is interfering with the audio.

To be sure, unplug every device connected to your Vizio TV and plug them back in one by one. If you notice that there is sound when you plug in a specific device, then it must be the source of the interference.

If you can’t find a solution, try unplugging your TV from the power outlet for a few minutes and then plugging it back in. Turn it on after doing so. If the issue is not resolved, contact your supplier or manufacturer.

7. Check Remote Batteries

If you’re experiencing problems with your volume, try to replace and/or test the batteries in your remote. If that doesn’t solve your problems, check to make sure that you are actually pressing the remote’s buttons and not another item nearby.

If your Vizio remote isn’t working, it doesn’t automatically mean that the TV is at fault. In order to determine what the problem is, you should first check out the battery compartment and make sure that the batteries are properly installed and in good shape. If this does not solve the issue, it’s possible that your remote has been damaged for some reason or it just needs to be reset.

If the Vizio TV remote won’t turn the volume up or down, it might be because of a few reasons. If the remote seems to have buttons available, but the volume will not change, there might be something stuck under the buttons. You can fix this by following these steps.

If your Vizio remote doesn’t seem to be working, there is a chance that you can fix the problem in a few simple steps.

You will need to discharge any residual power in the remote to get it working again. Remove all batteries from the remote and press every button several times. This will clear the memory and reset the device. After that, reinsert the batteries and try using the remote again.

If for whatever reason, you don’t have the Vizio remote that came with the TV, you can use your Xfinity remote or any other of your remotes. The only thing is that these remotes need to be paired to the Vizio TV in order for them to work. If you have a different Vizio remote, I recommend you check out your remote’s operating manual before proceeding.

If you’ve tried this and the sound is still low, the problem might not be the volume buttons themselves. Check to make sure the TV is unmuted, and that the volume of any external speakers has been increased all the way up.

8. Disable SRS TruVolume

Fluctuating volume or volume that cuts in and out is usually due to one of your devices conflicting with the settings on your TV. The first thing you should do is to unplug all of your devices and check the volume in just your Vizio TV’s apps. The main issue is the ‘SRS TruVolume’ function — you’ll need to disable this feature, which can be done from ‘Settings’, ‘Sound’, and then disabling the TruVolume button.

The Vizio TV’s TruVolume feature automatically adjusts the volume of your content based on the onscreen action. This feature can occasionally conflict with external devices, like gaming consoles and set-top boxes like Roku, Chromecast, and Amazon Fire.

If you’re using your TV alongside external devices like a sound system, Vizio SRS TruVolume can cause some issues. You can solve this by changing the setting from ‘Prefer SRS’ to ‘Off.’

Step 1: Navigate to Audio Settings > Advanced Audio

Step 2: Change the setting from ‘Prefer SRS’ to ‘Off’.

Turn off any settings on your Vizio TV that may change the audio volume. If you have “TruSurround” or “Surround Sound” enabled, try disabling those settings. Other common culprits include analog output settings being set to “variable” rather than “fixed.

9. Update software on Vizio TV

The software on your Vizio TV can sometimes be at fault for issues. Some factory reset codes can cause the sound to stop working, but you’ll never know unless you Google it.

Fortunately, Vizio TVs are automatically connected to the internet. Within hours of a software update being released, you should see it automatically pop up in your system settings. If it doesn’t appear, check your connection and try again later.

Sometimes, Vizio TVs lose the ability to produce sound. This is usually caused by outdated software or being disconnected from the internet.

Thankfully, this issue is easy to solve. You can simply check if your TV has the latest software version — which should also solve the issue — or you can try manually updating it if you’re not connected to the internet.

First, press the V key on your TV remote. This takes you to the System tab. Look for Check For Updates in the menu dropdown. Click it and your TV will start looking for any available updates.

If an update is available, confirm the installation. Your TV will download the update, restart, install the update and restart one more time.

10. Do A Factory Reset

If nothing so far works, it’s time to revert your Vizio TV back to its factory settings. Do this by going into Settings and selecting the Reset option. This will revert your TV settings to the ones it had when you first bought it. However, any manual changes you made to the TV settings will be lost.

A factory reset should eliminate any software problems, so that leaves the hardware.

Note: The factory reset will erase all of your settings, including any WiFi passwords or Internet connection configurations.

If your Vizio television isn’t performing as it should, it might be necessary to reset the device. Here are instructions on how to factory reset a Vizio TV to default settings:

Press the TV button on your remote control.

Scroll down and select Settings. Select System, then Reset & Admin. Choose Reset TV to Factory Defaults and press OK.

Choose Reset, press OK again, and wait for the TV to turn off.

The TV will automatically reset to factory settings. Press the menu button on your tv remote and navigate to ‘initial setup’ or ‘set-up’. Select this to run through the full setup and set up your TV it’s best you do this first before anything else.

Vizio TV Volume Control Not Working

Vizio TVs are some of the best TVs on the market and are known for their superb picture quality and high definition resolution, but what happens if your remote is not working?

If you have a Vizio TV, you may be experiencing an issue with your remote — it’s not working properly. The first step to fixing any problem is identifying what the problem is.

First and foremost, check the Remote Control Sensor. Make sure it has line of sight with the TV. If you can’t find any issues like this then take a look at your Vizio TV’s Power Settings. Selecting “Eco” Mode will disable remote control functionality on the Vizio TV as well as some other settings. Some users have reported that putting their TV in “Game Mode” eliminates the problem.

A Vizio television’s volume buttons may fail for a variety of reasons. This may include a physical issue with the buttons, as well as a problem with the remote control. In such cases, you will have to replace the remote or reset it to fix the issue.

Why Isn’t The Sound Working On My Vizio TV

The fix is to press your remote’s volume up button once or twice. Once it has been pressed twice, then you can turn the TV off and on again. This should fix the issue of having no audio when you first turn the TV on.

When your TV isn’t producing any sound, one of the first things you should check is that you haven’t turned down the volume or muted the TV. Most TVs have a built-in audio processor that allows you to adjust the volume and select surround sound mode — make sure these are turned up. If you’re using external speakers or earphones, check the connections to make sure they’re all properly plugged in.
