You may have noticed that the volume on your Vizio TV has a mind of its own. Many Vizio users have reported that the volume fluctuates at random, cuts in and out, or does not respond at all.
If you discover that your TV is behaving similarly, this article will provide a number of solutions that you can try to resolve the issue. If audio settings, such as ‘TruVolume,’ conflict with your device, the volume of your Vizio TV will fluctuate.
It could also be a firmware bug, a broken volume button, a faulty cable, or a problem with the TV’s output settings. If there is debris under the buttons or a remote is not paired, the volume may not respond at all.
More information about these issues and their solutions can be found below. You can also learn how to fix your TV’s volume if it is too low, as well as how to display the volume on your TV in an easy way.
VIZIO TV NO SOUND/NOT WORKING
After a long day at work, it’s time to unwind, and your Vizio Smart TV is giving you the silent treatment. You scratch your head and wonder why your Vizio TV suddenly has no sound or the sound has stopped working.
If the sound on your Vizio TV isn’t working, there are three things to look into. To begin, ensure that your volume is not muted or set to zero. Second, ensure that your TV is not set to use an external speaker/headphones that are turned off. Third, make sure your TV speakers are turned on.
If your Vizio TV volume is muted or set to zero, this should be a simple fix of unmuting and/or gradually increasing your volume. If your Vizio TV is configured to use external speakers/headphones, make sure they are turned off or turned down very low.
To test your TV’s internal speakers, you could either turn on/increase the volume of the external speakers or set your TV to not use external speakers/headphones. If neither of the preceding suggestions worked.
Check that your TV speakers are turned on. You can do this by using your remote to navigate to your Vizio TV’s Audio Settings and then turning on the TV Speakers setting.
If all else fails and your Vizio TV still does not have sound, try power cycling it by unplugging the power cord from the wall power outlet. For about 5 seconds, hold down the power button on the TV. Then, reconnect the TV to the power outlet and turn it on.
VIZIO TV SOUND KEEPS GOING IN AND OUT/KEEPS CHANGING
Fluctuating volume or volume that cuts in and out is usually caused by one of your devices interfering with your TV’s settings.
You can test this by unplugging all external devices and only using the Vizio TV’s apps to check the volume. The main problem is with the ‘SRS TruVolume’ function.

1. Disable SRS TruVolume Function
The SRS TruVolume function adjusts the volume automatically for a better audio experience. Regrettably, this frequently clashes with the settings on an external device.
As a result, disabling this feature may resolve your issues. You can accomplish this by following the steps outlined below.
- On the remote, press the ‘Menu’ button.
- Select Audio Settings > Advanced Audio.
- Set ‘RSS TruVolume’ to ‘Off.’
Any other settings that automatically adjust your audio can contribute to abnormal volume fluctuations. Among these options are ‘TruSurround,’ ‘Surround Sound,’ and ‘Volume Levelling.’
Even settings like ‘Analog Output’ set to ‘Variable’ can have an impact. Change any ‘auto’ or ‘variable’ settings to ‘fixed’ instead.
Check the audio settings on your device, such as a set-top box or gaming console. You must disable any settings that allow the device to adjust your volume automatically. If this does not resolve your problem, try the general troubleshooting techniques listed below.
2. Performing A Hard Reset
A hard reset will allow your TV to clear out any unnecessary data that may be interfering with its performance.
This will not delete any of your downloaded data or preferences, making it safe to use whenever you are experiencing problems.
- Turn off your TV and any other devices that are connected to it.
- Unplug the TV from the power source.
- For 30 seconds, press and hold the ‘Power’ button on the TV.
- Wait another ten minutes with the TV turned off.
- Reconnect the TV and turn it on.
3. Performing A Factory Reset
A factory reset is an extremely effective method of resolving unknown issues with your Vizio TV because it restores the TV’s original settings, including the original firmware.
This reset, however, will delete all of your saved preferences and downloaded content, so only do it if you are certain there is no other option. If you want to restore your TV to factory settings, follow the instructions below.
- On the remote, press the ‘Menu’ button.
- Select Settings > Reset & Admin.
- Choose ‘Reset TV to Factory Defaults.’
- Enter the passcode for your TV or the default code ‘0000’.
- To conform the factory reset, select ‘Reset.’
- Wait until the TV has completely restarted before beginning the setup process.
Keep in mind that if this is a bug in the latest firmware, you may want to wait until a new update is available before updating the TV.
4. Check Your Cables
If your sound is cutting in and out, it could be due to a faulty or loose cable. Any cable, such as an HDMI or coaxial cable, can be used. To begin, unplug and re-insert the cables, pushing them in as far as they will go.
If this does not resolve the problem, try your cable in a different TV or a new cable in your TV to see if it is faulty. You should also ensure that your cable is compatible with the audio/visual signal being delivered to your television.
VIZIO TV VOLUME WON’T TURN UP/DOWN
If the volume on your Vizio TV isn’t working, make sure it’s not a problem with the remote or TV buttons. If you’re using a remote, start by replacing the batteries. However, if the batteries are running low, none of the buttons should function.
If it is only the volume buttons on the remote, you may have debris stuck between the pads, or the remote may need to be reset. You can accomplish this by following the steps below.
- Remove the remote’s batteries.
- At least once, press each button on the remote. This will remove any remaining power from the remote, completing the reset.
- To dislodge any debris beneath the pad, press both volume buttons several times.
- Replace the batteries and test the volume controls again.
You could also be using a remote other than the Vizio remote, such as your Xfinity remote. These remotes must be paired with the TV in order to function.
The operating manual for your remote will show you how to pair it. If the volume buttons on the back of the TV (below the power button) are not working, try pressing them several times to dislodge any debris.
You can also perform a hard reset on the television, as described above. However, it’s possible that the problem isn’t with the volume controls. Check that the television is not muted and that the volume of any external speakers is set to maximum.
VIZIO TV VOLUME LOW
If you’re having trouble hearing your TV’s audio, make sure the TV speakers or an external speaker are turned on. Follow the steps below to activate your TV’s internal speakers.
- On your remote, press the ‘Menu’ button.
- Go to Audio Settings > TV Speakers > Turn On.
If you’re using an external speaker, make sure the cables are properly connected and that the TV audio settings are set to accept external audio. You can change the settings outlined below by going to the same Audio Settings as described above.
- ‘TV Speakers’ should be set to ‘Off.’
- Change the ‘Digital Audio Out’ setting to ‘Bitstream.’
- Change the ‘Analog Audio Out’ setting to ‘Fixed.’
- Turn ‘Volume Leveling’ off.
- Set ‘Surround Sound’ to ‘On’ if you want to use surround sound.
It’s also possible that the ‘TruVolume’ feature is making your audio sound softer than usual. If this is the case, you can disable this feature by following the steps outlined above.
Check the volume settings on your device as well, such as your cable TV box or gaming console. You may be able to increase the volume through the internal settings.
VIZIO TV SOUND KEEPS GOING DOWN
Because of the ‘TruVolume’ setting or other volume features listed at the beginning of this article, your volume may continue to drop. It’s also possible that the ‘volume down’ button on your remote or the back of your TV is pressed and stuck.
In this case, you must perform a remote reset or unstick the button as described above. Another possibility is that you have an old Vizio remote in your house.
Because these remotes have similar programming, they can interfere with the signals, sending commands to your television without your knowledge.
You can test this by turning off the infrared receiver on the TV and seeing if the problem goes away. If it does, your next problem will be locating the remote or another device that is interfering with your television.
Sound problems are common not only on Vizio TVs, but in most AV devices. Fortunately, most problems aren’t that difficult to resolve. You should be able to troubleshoot and repair sound issues on a Vizio TV using the tips provided above.
