Vizio TV No Sound / Not Working

You may have been watching your Vizio TV and noticed that the volume has a mind of its own. Many Vizio users have reported that the volume can randomly fluctuate, cut in and out or not respond. If you are finding your TV is doing the same, this article will provide a number of solutions you can try to fix it.

A Vizio TV’s volume will fluctuate if audio settings, such as ‘TruVolume’, conflict with your device. It may also be a firmware bug, a failing volume button, a faulty cable or the TV’s output settings. The volume may not respond at all if there is debris under the buttons or a remote is not paired.

Vizio TV No Sound / Not Working

After a long day of work, it’s time to relax and you find yourself your Vizio Smart TV giving you a silent treatment. You scratch your head and wonder why all of the sudden your Vizio TV has no sound or the sound stopped working.

As a general rule, there are 3 things to check if your Vizio TV sound is not working. First, check if your volume is not muted or set to zero. Second, make sure your TV is not set to use external speaker/headphones that is turned off. Third, make sure your TV speakers are set to “On” position.

If your Vizio TV volume is muted or set to zero, this should be a straight forward fix by unmuting and/or increasing your volume gradually.

If your Vizio TV is set to use external speaker/headphones that is turned off or turned down very low. You could either turn on/up the external speaker volume or set your TV to not use external speaker/headphones to test out your TV’s internal speakers.

If both of the above suggestions didn’t help. Make sure your TV speakers are turned on. You can do this by using your remote to go to the Audio Settings of your Vizio TV then turn on the TV Speakers setting.

If all fails and your Vizio TV still has no sound, try to power cycle your Vizio TV by unplugging the power cord of your TV from the wall power outlet. Hold down the power button on the TV for about 5 seconds. Then plug the TV back in to the power outlet and power on the TV.

Vizio TV Sound Keeps Going In and Out/Keeps Changing

Fluctuating volume or volume that cuts in and out is usually due to one of your devices conflicting with the settings on your TV. You can check this by unplugging all external devices and checking the volume in just your Vizio TV’s apps. The main issue is the ‘SRS TruVolume’ function.

Disable SRS TruVolume Function

The SRS TruVolume is a function that automatically adjusts the volume for a better audio experience. Unfortunately, this often conflicts with the settings on an external device.

For this reason, disabling this feature could fix your issues. You can do this by following the steps below.

Step 1: Press the ‘Menu’ button on the remote.

Step 2: Navigate to Audio Settings > Advanced Audio

Step 3: Change ‘RSS TruVolume’ to ‘Off’.

Any other settings that are automatically adjusting your audio can play a part in causing abnormal volume fluctuations. Some of these settings include ‘TruSurround’, ‘Surround Sound’ and ‘Volume Levelling’.

Even settings such as ‘Analog Output’ that are set to ‘Variable’ can affect this. Try changing anything that is ‘auto’ or ‘variable’ to ‘fixed’ instead.

You should also check the audio settings in your device, such as a set-top box or gaming console. You will need to disable any settings that allow the device to automatically adjust your volume. If this does not solve your issue, below are some general troubleshooting techniques you can try.

Performing a Hard Reset

A hard reset will allow you TV to unload any unnecessary data that might be affecting its performance. This will not delete any of your downloaded data or preferences, so it safe to perform whenever you are having issues.

Step 1: Turn of your TV and all connected devices.

Step 2: Unplug the TV from the wall power.

Step 3: Press and hold the ‘Power’ button on the TV for 30 seconds.

Step 4: Wait another 10 minutes with the TV unplugged.

Step 5: Plug the TV back in and turn it on.

Performing a Factory Reset

A factory reset is a very effective method of fixing unknown issues with your Vizio TV. This will restore the TV’s original settings, including the original firmware.

However, this reset will delete all of your saved preferences and downloaded content, so only do this if you are sure there is no other way. If you do want to reset your TV to factory settings, follow the steps below.

Step 1: Press the ‘Menu’ button on the remote.

Step 2: Navigate to Settings > Reset & Admin.

Step 3: Select ‘Reset TV to Factory Defaults’.

Step 4: Enter your TVs passcode or the default code ‘0000’.

Step 5: Select ‘Reset’ to conform the factory reset.

Step 6: Wait until the TV has fully restarted before you begin the set-up process.

Note that if this is a bug in the latest firmware, you might not want to update the TV until you know there is a new update available.

Update the TV’s Firmware

Another possibility is that you are operating firmware that has a fault or bug in it. When Vizio become aware of common bugs in the firmware, they will fix it and release a new update.

Normally your TV will automatically download and install this update. If you suspect that you are still running old firmware, you can manually update your Vizio TV using the steps below.

Step 1: Press the ‘Menu’ button on your remote.

Step 2: Navigate to Settings > Check for Updates

Step 3: If an update is available, confirm that you want to install it.

Check your Cables

If your sound is cutting in and out, you may have a faulty or loose cable. This can be any cable, such as a HDMI or coaxial cable. First, make sure you unplug and re-insert the cables; pushing them in as far as they can go.

If this doesn’t solve the issue, you can either try your cable in a different TV or try a new cable in your TV to determine if it is faulty. You should also make sure your cable is compatible with the audio/visual signal that is being delivered to your TV.

Vizio TV Volume Won’t Turn Up/Down

If your Vizio TV volume does not work, make sure that it is not the remote or TV buttons that are failing. If you are using a remote, you can try replacing the batteries first. However, if the batteries are dying, none of the buttons should work.

If it is exclusively the remote volume buttons, you may have debris stuck under the pads, or the remote might need to be reset. You can do this using the following steps.

Step 1: Remove the batteries from the remote.

Step 2: Press every button on the remote at least once. This will discharge any remnant power from the remote to complete the reset.

Step 3: Press both volume buttons several times to dislodge any debris beneath the pad.

Step 4: Re-insert the batteries and try the volume buttons again.

Alternatively, you may be using a remote other than the Vizio remote, such as your Xfinity remote. These remotes need to be paired to the TV in order to work. You can see how to pair the remote in your remote’s operating manual.

If it is the volume buttons on the back of the TV that are not working (below the power button), you can try pressing them multiple times to dislodge any debris. You can also perform a hard reset of the TV, which is detailed above.

However, it may not be the volume buttons that are causing the trouble. Check that the TV is unmuted and that the volume of any external speakers has been increased to maximum.

Vizio TV Volume Low

It may seem simple, but if you are struggling to hear your TV’s audio, make sure the TV speakers or external speaker is turned on. To turn on your TV’s internal speakers, follow the steps below.

Step 1: Press the ‘Menu’ button on your remote.

Step 2: Navigate to Audio Settings > TV Speakers > On.

If you are using an external speaker, make sure the cables are connected properly and that the TV audio settings are optimum for external audio. If you navigate to the same Audio Settings as above, you can change the settings outlined below.

Step 1: Set ‘TV Speakers’ to ‘Off’.

Step 2: Set ‘Digital Audio Out’ to ‘Bitstream’.

Step 3: Set ‘Analog Audio Out’ to ‘Fixed’.

Step 4: Set ‘Volume Levelling’ to ‘Off’.

Step 5: If you are using surround sound, set ‘Surround Sound’ to ‘On’.

It may also be the ‘TruVolume’ feature causing your audio to seem softer than usual. If this is the case, you can find how to disable this feature above.

You should also check the volume settings on your device, such as your cable TV box or gaming console. You may have the option to increase the volume from the internal settings.

Vizio TV Sound Keeps Going Down

You volume may keep going down due to the ‘TruVolume’ setting, or other volume features, which you can find at the beginning of this article.

It may also be that the ‘volume down’ button, either on your remote or on the back of your TV, is pressed down and stuck. In this case, you will need to perform a remote reset, or unstick the button, detailed above.

Another reason for this may be an old Vizio remote in your home. As these remotes have similar programming, they can interfere with the signals, issuing commands to your TV without you realising it.
