Watching a Vizio TV is only immersive if it meets two conditions: high-definition images and sound. The climactic sound of explosions or the subtle background noise in a conversation is what enhances your viewing experience. However, it can be shocking when you turn on your Vizio TV only to find that it doesn’t have sound.
Your Vizio TV may not have sound for several reasons, including incorrect audio settings on the TV, the TV is muted, the volume is at zero, or the speaker is turned off. Solutions include disabling the mute mode, raising the TV’s volume, updating the TV, and changing the audio settings.
In the rest of this article, I’ll discuss the reasons a Vizio TV may not have sound. I’ll also take you through how to solve the problem. Keep reading!
Why Your Vizio TV Doesn’t Have Sound
A Vizio TV that doesn’t have sound can demoralize you from watching a favorite show on platforms like Netflix. The frustrating bit is that you may remain stuck on the screen, not knowing the cause and what to do about it. There are many reasons for this, and I’ll discuss them all in the following sections:
The TV’s Volume Is Zero
Like any other TV brand, you can lower your Vizio TV’s volume to zero. The unfortunate fact is that you might reduce the volume to zero unintentionally. Some of the causes of this include:
- The TV remote’s volume buttons being pressed inadvertently.
- Miscommunication between the TV and its remote.
- Using a universal remote without programming it correctly.
The TV Is on Mute
Vizio TVs have a mute button on the remote control. It may be easy to press this button, muting the TV’s sound accidentally.
Alternatively, you might have muted the TV to receive a phone or speak to someone and forgot about it.
The TV’s Speakers Are Off
Vizio TVs have speakers that can be turned off through its menu options. Your TV won’t have sound if you turn off the speakers. This may happen when you’re using external speakers, and you want to turn off the TV’s speakers. Consequently, you might forget you had turned off the TV’s speakers when it comes time to use them.
Incorrect Audio Settings
The sound/audio settings of your Vizio smart TV may not be correct. This can happen if you or someone else changes the settings without understanding them.
Incorrect audio settings means you won’t hear any sound even if the TV’s volume and speakers are on. This is because the settings don’t correspond with your TV’s sound abilities or external devices, like surround sound systems or soundbars.
Faulty Audio Source Connection
This is usually the problem if you’ve connected the TV to an external device, like a DVD player or soundbar. Additionally the audio source may not have a proper connection to the TV, which can happen if the cable connecting them is faulty or loosely connected.
Your Vizio TV Is Using Outdated Software
Smart TVs use software, just like computers do. If the software is outdated, it may not be compatible with external devices, resulting in a lack of sound.

It’s worth noting that TV companies update their operating software regularly to enhance performance and fix any bugs. Therefore, if your TV operates outdated software when there is an updated version, it’s likely to experience many problems, including the lack of sound.
5 Easy Fixes for a Vizio TV That Doesn’t Have Sound
At this point, you know the potential reasons your Vizio TV doesn’t have sound. It’s time to get into the nitty gritty of fixing the problem.
Disable Mute Mode
The first fix you want to try is to disable the mute mode. Unfortunately, you may not know if the lack of sound is due to a muted TV. Therefore, this fix relies on trial.
To disable the mute mode, locate the “Mute” button on your TV’s remote and press it once. If the sound isn’t restored, then the TV was not on mute. Thus, it means you just activated the mute mode by pressing the mute button. You should press the mute button again to disable the mute mode.
Raise the Volume
It may seem obvious, but you want to check that the volume on your Vizio TV isn’t too low. You can do this by pressing the “Volume Up” button on the remote or the TV’s menu options. If there is no change, proceed to the next fix below.
Check and Change the Audio Settings
You should check and ensure the TV’s audio settings are correct. This includes checking if the speakers and external audio devices (like soundbars) are correctly connected and turned on. Ideally, the TV’s audio out should be set to PCM. If not, change the setting to PCM using the procedure below:
- Click the Menu button on the remote.
- Navigate to Audio.
- Scroll to Digital Audio Out.
- Switch the option from Dolby D or Bitstream to PCM.
- Scroll up to volume leveling and turn it off.
Check External Device Connection
The next fix is to inspect the connections on the external devices connected to your Vizio TV. Ensure they’re correctly plugged in, and the cables aren’t damaged or loose.
If you’re using an HDMI cable, try reseating it. Reseating an HDMI cable is simply unplugging it from the port and plugging it back. You should ensure the cable is correctly seated into the port.
You can try a new HDMI cable if reseating the old one doesn’t work, as the problem could be due to a faulty HDMI cable.
Update the Vizio TV’s Software
Updating the TV’s software may solve compatibility issues with external devices and fix any bugs causing the lack of sound. The following procedure will help you check and update your Vizio TV’s software:

- If there is an update, click “Update Now” to begin the update process. Wait for the update to complete and restart the TV.
- Check if the sound is restored.
Final Thoughts
A Vizio TV with no sound means you can’t enjoy your favorite shows peacefully. If this is the case, ensure the TV is not muted or at zero volume before proceeding to the other fixes.
