Check if your remote control is working
The remote controls for Vizio TVs may stop functioning properly because of dead batteries or other problems.
If you’re having trouble with the TV volume, that might very likely be the situation with you. So, it’s always a good idea to begin troubleshooting by making sure your remote is operational.
Vizio could save on design activity by limiting TV sizes and features to the ones that were most in demand.
Activate the volume controls on your remote while your TV is on. Replace the remote’s battery if the TV is not responding to commands from the remote.
Unfortunately, it’s time to purchase a new remote if changing the batteries does not solve the problem. If the remote control functions successfully, go to the following step.
Ensure the TV is not muted
Even though it’s evident that most people would have already checked this, it’s still important to bring it up before moving on.
In light of this, make sure your Vizio TV is not muted when using the remote. Moreover, depending on the TV type you’re using, turn up the volume either on the TV or using the remote control.
When you have done this, and the sound on your Vizio TV is still not working despite not being muted, you can quickly power cycle the device to resolve the problem.
Check the Vizio TV’s volume
If your TV isn’t muted, but you’re still not hearing any sound, your TV’s volume may have been accidentally adjusted to 0.
Press the volume button on the “+” side with your TV remote. Make sure the TV volume is set to something audible that is higher than 0.
If the TV volume is set correctly, but you still can’t hear anything, you can find relief by checking your HDMI cable.
Examine your HDMI cable
The transmission of audio and video signals to the TV is greatly aided by HDMI cables. If the HDMI cable that connects your TV to an external device is broken, your Vizio TV may have volume problems.
It’s likely that your HDMI cable is broken if you can watch video on your TV but not hear any audio. To see if the audio problem is resolved, consider using a different HDMI cable.
If the audio problems are resolved after using a different cable, the HDMI cable you were previously using must have been defective.
Update Software on your Vizio TV
Your Vizio TV’s sound may occasionally cease operating due to software difficulties. Always check to see if your TV is using the most recent software.
In most instances, your Vizio TV should automatically look for and install new software updates as long as it’s connected to the internet. But on occasion, this procedure is halted, and your TV becomes trapped using out-of-date software.
To manually update the software on your Vizio TV:
- On the TV remote, press the V key.
- Choose System in the drop-down menu.
- Next, select Check for Updates.
- The search for any available upgrades on your TV will begin.
- Verify the installation of any updates if they are available.
- The update will be downloaded, installed, and then your TV will restart.
- To fix sound issues, update the Vizio TV software.
Check to see if your sound difficulties have been resolved after the second restart.

Verify that SAP is activated on your Vizio TV
SAP, or secondary audio programming, refers to the process of watching a TV show in a language other than that of the original language. Usually, the TV program includes a second audio stream.
If you prefer to see the program in its native language, you can switch off SAP on your TV. Popular menu names for SAP include “SAP,” “Audio Choose,” “B-Audio,” “MTS,” etc. To make sure SAP is enabled on your Vizio TV, follow these steps:
- Your TV remote’s “menu” button should be pressed.
- From the list of available options, pick ‘Audio’.
- Choose the “SAP” option.
- Choose the preferred setting.
Disable DTS TruSurround on your Vizio TV
Many Vizio TV owners complain that the TV’s extensive audio settings cause volume problems.
Your Vizio TV’s audio problems could be brought on by a conflict between the show you are watching and DTS TruSurround.
In this case, turning off the advanced setting might be helpful. Follow these instructions to disable DTS TruSurround on your Vizio TV:
- Choose Main Menu.
- Go to Audio Settings.
- Go to Advanced Audio.
- Deactivate DTS TruSurround.
Replace the power cord in the back of the Vizio TV
Remove the power cord from the TV’s back for another quite simple potential solution. After around 60 seconds of being unplugged, plug it back in.
Make sure the connection is secure when you re-plug it. A tight connection is necessary to guarantee that the TV is receiving stable power. Therefore, you don’t want it to be at all slack.
Use the TV’s power button to turn the TV on after you’ve reconnected the power cord. Perhaps you can see the TV turn back on and hear the sound once more.
Get in touch with the Customer Support
It’s likely that none of the suggestions above will help, and your audio problems will continue.
