Good audio quality is important for a satisfactory viewing experience. If you encounter problems like low volume or the volume not working at all, it can be quite annoying. Despite being one of the best smart TV brands, Vizio TVs may have problems of their own. If the sound on your Vizio TV is not working, you are not alone. The problem could be due to a number of factors. Whether you are relying on the TV’s inbuilt speakers or an external sound bar for audio output, a number of factors can impact the volume of your TV. In this article, we have explored a few options regarding what to do if you encounter a no volume problem on your Vizio TV.
Check the TV’s volume
Prior to trying any troubleshooting steps, you must ensure that your Vizio TV is not muted. While it may seem very basic, it is worth ruling out the possibility before taking the next step. Press the mute button on the remote control to see if the volume increases.
However, if the TV is not muted, check the TV volume to ensure it has not been set to zero. Use the + volume button on the TV remote to see if you can hear sound on your Vizio TV.
In case, your TV is not on mute and the volume has not been set to zero, but the sound is still not working, you must proceed with other troubleshooting steps.
Check your TV remote control
It is also important to check your Vizio TV remote control to ensure it is working. At times, the batteries may need a replacement, or there may be some other issue with the remote control. To check this, use the volume control on the Vizio TV to see if the sound is fixed.
If yes, it implies there is a problem with the remote control. You may either need to change the dead batteries, get the remote checked to restore its functionality, or replace your Vizio remote control with a new one.
Check External Audio
One reason the Vizio Tv volume is not working could be an external device attached to the TV that you may have forgotten to remove.
If you have headphones, external speakers, or an external sound bar connected to the TV, the audio signals may be transmitted to the connected device, not the TV speakers. The audio devices may be muted or not in range, which may be why your Vizio TV has no sound.
To resolve this problem, all you need to do is check your TV’s AUX port and disconnect any external device that is not in use.
Power cycle your Vizio TV
The next step you can try to restore Vizio TV sound is applying a soft reset or power cycling your TV. This will reset your Vizio TV without changing any settings or deleting the data and clear out any corrupt cache files hindering the TV audio.
To power cycle, unplug the Vizio TV by removing the power cord from the power outlet. Wait for at least sixty seconds before plugging the TV back in, and press the power button on the Vizio TV for thirty seconds to remove any residual power from the TV.
Now turn on the TV by plugging the power cord back into the outlet and check if Vizio TV’s volume is restored.
Check your Vizio TV Audio Settings
The next thing you need to check is the audio settings of your Vizio TV. Ideally, the audio should be set to PCM.
The digital audio output settings are one of the main reasons why Vizio TVs sound may stop working. To resolve the issue, here is how you can set the audio output to PCM.
Press the menu button on the Vizio remote
Navigate to audio and select it to get to Digital Audio Out.
Now switch this option to PCM.
You may also need to check the TV volume leveling and turn it off. You will find this option in the audio setting section. Check to see if volume leveling is enabled. If yes, then turn it off.
Another aspect you must check is the surround sound option. Many Vizio TV owners complain about sound issues due to the advanced audio settings of the device.
If the DTS TruSurround option is enabled, it may be hindering the audio output of the program you are watching and could be the reason for the Vizio TV no sound problem.
To disable it, go to the main menu and select audio settings. Now tap on Advanced Audio and disable DTS TruSurround by turning it off. Once you have disabled the option, restart the TV to see if the problem is resolved.
If adjusting the audio settings is not fruitful, we must proceed to the next step.
Check your HDMI cable
HDMI cables play a significant role in transmitting the TV’s audio and video signals. If the HDMI cable that connects your Vizio TV to any external device is faulty or broken, the TV may have sound problems.
Therefore, if you can watch videos on the TV but cannot hear any sounds, there is a probability that the HDMI cable is broken. You can use a different HDMI cable to see if the Vizio TV’s sound is restored.
If the volume is working again, it means that the HDMI cable used previously was broken, and replacing it with a new HDMI cable has fixed the problem.
While at it, check the TV’s power cord to ensure it is not the problem.
Check the Volume Settings of your Cable or Satellite Box
If you have a cable or satellite box connected to the TV, the video and audio signals are transmitted through it to the TV. If that is the case, you must check the device’s volume settings to ensure that it is not the case.
To check this, use the device’s remote and ensure it is not on mute. If yes, use the remote’s volume buttons to raise the volume to an audible level.
Enable Vizio TV SAP
SAP (secondary audio programming) is a process whereby you can watch a TV show in a language other than the original language of the program. In such a case, the TV program also comprises a second audio stream.
If you want to view the program in its original language, you can disable SAP on your Vizio TV. The terms used to refer to SAP include MTS, Audio Choose, B-Audio, or simply SAP.
However, if you want to enable SAP, press the menu button on your Vizio TV remote and select audio. Now select the SAP option to enable or disable SAP as you prefer.
Update Vizio TV software
The Vizio TV sound may sometimes not work due to a software glitch. If that is the case, there is nothing to panic about, as it can easily be resolved by updating the Vizio TV for the latest firmware.
Usually, Vizio TVs automatically check for new software updates and install them accordingly when connected to the internet. However, the updates may sometimes be interrupted, and you may need to enable the process manually.
Therefore, to update your Vizio Smart TV software, here is what you need to do.
Locate the V button on the Vizio TV remote and press it.
You will be prompted to a menu from where you must select System.
Tap on Check for Updates.
If there are any updates available, select install.
The Tv may restart a few times during the updates download and installation.
Reset your Vizio TV
You can apply a factory reset to resolve the audio issues if nothing else has worked to restore your Vizio TV’s volume. A factory resetting is a hard reset that will restore your Vizio TV to its initial settings when it was first purchased, and you may need to reinstall apps.
However, it will also remove any bugs and may be exactly what you need to restore your TV’s volume.
Here is what you need to do to reset TV.
Navigate to the main menu by pressing the menu button on the Vizio remote.
Select the System option and tap on Reset and Admin option when the option opens.
Now press off and add the parental code. Alternatively, you can put 0000 as the password if you have not activated a code.
Now tap on reset and press OK.
The Vizio TV will turn off once the reset process is complete and will start to reboot. Once the TV restarts, the Setup App process will initiate.
Contact Vizio Support Team
Hopefully, your Vizio TV audio issue is resolved. If not, it could be a hardware issue, and you may need to contact the Vizio customer support team for further guidance and technical assistance. You can find the support team information on Vizio TV’s website.
