How to Fix Volume Not Working On Vizio TV

When you are watching TV, there are diverse genres of content that you can watch and enjoy, such as music, sports, films, documentaries, soap operas, talk shows, reality shows, cooking, etc. You not only want to watch the pictures, but also listen to what the characters are saying, and your TV must have good volume, so that you can hear clearly.

However, sometimes you may find that the volume of your Vizio smart TV is not working. There are diverse reasons why this occurrence can happen. Users of Vizio TV often report this problem, because they find that the volume has fluctuated, does not respond, or cuts out and in. So, when you encounter such issues, you should not panic and think that it is a complicated issue. There are several things that you can do to fix it as you will see in this article.

Why Does My Vizio TV Have No Sound?

Some of the reasons why your Vizio TV’s volume can fluctuate include:

• TruVolume problems with your Vizio TV
• Audio settings
• Firmware bug
• A malfunctioning volume button
• The TV’s output settings
• A faulty cable
• Dirt under the remote’s button
• A faulty remote

My Vizio TV Has No Sound – How to fix it

After retiring from a hard day’s work, you can sit on your sofa and watch news, sports, soap operas, film, etc., as you relax and enjoy, while cooling down. You may be very disappointed when the programme that you are watching has reached the climax, only for the volume to go down suddenly. This is very frustrating, especially when you are keenly listening to what is rolling out. Obviously, you do not want to miss any bit of the climax.

The sudden disappearance of the volume can make you to bang your remote on the floor or the wall, or even punch the TV screen, when it fails to respond to all reparatory efforts that you make. You are left there gazing at the TV, but you cannot hear anything. When this happens, some of the things that you can do to restore the volume include:

• Check whether the volume is muted
• Is the TV set to use external speaker or headphones?
• Are the TV speakers set On?

When you check and find that your TV’s volume is set to nought or muted, you just have to increase it to your desired level, and if is muted, just unmute it.

If your Vizio TV is set to use headphones or external speaker, which is turned down very low or off, you can solve it by turning up/on the external speaker’s volume. Alternatively, you can set your Vizio TV to not use headphones/external speaker. This is necessary to test the external speaker of your TV.

The third option is by turning on your TV’s speaker using the remote. To do this, go to the Audio Settings of your Vizio TV, and turn on the Vizio TV Speakers’ settings.

When the three above solutions do not solve the sound problem, you can power-cycle your TV using this procedure:

• Unplug the Vizio TV’s power cable from the socket
• Long-press the TV’s power button for 5 seconds
• Re-plug the TV’s power cable to the socket
• Switch on your Vizio TV

When your Vizio TV’s Volume Keeps on Changing

When the TV’s volume keeps on fluctuating by going in and out, it becomes unstable, because it behaves like the waves of the sea that come and go. This is often as a result of one of the devices interfering with your TV’s settings. To solve it, you can unplug all external devices that are connected to your Vizio TV, and check whether the volume has been rectified. For instance, the main issue can be the SRS TruVolume function.

Deactivate the SRS TruVolume

The SRS TruVolume is a reliable function that adjusts the volume automatically for a better audio experience. Nevertheless, this function develops issues with the settings of an external gadget. When you disable this feature, there are diverse issues that are rectified. Use this procedure:

• Press the Vizio TV’s menu button
• Go to the audio settings (Advanced Audio)
• Change RSS TruVolume to Off

You can also check for any other settings, which automatically adjust your Vizio TV’s audio, because they cause unwanted volume fluctuations. Some of the settings include TruSurround, Volume Leveling, and Surround Sound.

When you set your TV’s Analogue Output to Variable, it can also affect the volume. When you find anything that bears the word “Auto” you can change it to “Fixed” or “Variable.” Do a thorough check of the audio settings on your gadget, like the gaming console, and the set-top box. Basically, disable all audio settings that tamper with the volume by adjusting them automatically.

How to do a hard reset on your Vizio TV

A hard reset unloads your TV off all unwanted data that can affect its performance. However, it does not delete the preferences or downloaded data. You can do it when your Vizio TV develops issues, because it is safe. Use this procedure:

• Switch off your Vizio TV and all other connected gadgets
• Disconnect the TV from the power socket
• Press-hold the Vizio TV’s Power button for over 30 seconds
• Wait for 10 minutes when the TV is still unplugged from the source of power
• Reconnect the TV’s power cable to the socket and switch it on

How to update the TV’s firmware

If you are using a firmware that has a bug or fault in it, it may also bring about volume issues. Fortunately, when Vizio gets to know that there are bugs in their TV firmware, they fix it by releasing another update. Amazingly, if you have set your Vizio TV to automatic updates, it will download and update the firmware on its own. However, if you have not activated this feature, you will have to manually search for new updates, and install them using this procedure:

• Press the Menu button on your remote
• Go to Settings > Check for Updates
• If there is any pending update, Confirm for installation

Check the TV cables

When your Vizio TV’s sound keeps on cutting in and out, it could be as a result of a loose or faulty cable, e.g. the coaxial or HDMI cable. The best to do is to unplug and re-plug the cable in the port properly and correctly. If the problem is not yet solved, try the cable on another TV to see whether the issue will be solved. You can also try out a new cable on your Vizio TV. Lastly, check whether your cable is compatible with the visual and audio signal that is being delivered to your TV.

Vizio TV’s volume does not turn Up/Down

If there are issues with your Vizio TV volume, ensure that it is not the TV or remote buttons that are faulty. If you use the remote, you can try pressing other buttons on it to see whether the TV will respond. When it responds, then the entire remote has no issues, but the volume key could be having problems. If the volume button is faulty, there could be debris lying under the button, and you should clean it to solve the problem. However, if no button responds, you can check the remote batteries first.

The Vizio TV’s volume is low

When your Vizio TV has no sound or low volume, ensure that the TV speakers or external speakers have been switched on:

• Press the Menu button on your remote
• Go to Audio Settings > TV Speakers > On

For external speakers, ensure that the cables are properly connected, and the TV’s audio settings are optimized for external audio.

How to do a factory reset on your Vizio TV

When you try the aforementioned methods to solve the volume issue in vain, you can finally decide to factory reset your Vizio TV. This reset does away with all customized settings, which you may not know, and restores the original default settings that were installed by the manufacturer. If the volume issues were being caused by customized settings, they will automatically be solved.

However, factory resetting your Vizio TV deletes everything else that the TV did not come with. This includes your downloaded content and preferences. Therefore, you should be ready to lose them when doing it using this procedure:

• Press the Menu button on your remote
• Go to Settings > Reset and Admin
• Choose “Reset TV to Factory Defaults”
• Enter the TV’s default code 0000 or passcode
• Choose Reset to confirm the factory reset
• Wait until the TV has fully restarted, then start the set-up process

Conclusion

To put it all together, you have learnt how to sort out volume issues on your Vizio TV. This is common issue, not only among Vizio TVs, but also among all TV brands. Sometimes, sound can disappear right from the media station that is airing what you are watching, and your TV will not have it either.
