Ways to Fix the Vizio TV No Sound Error

Here are several ways by which you can fix the issue of the Vizio TV volume not working. And now, you are going to learn about a few of such ways.

Besides, if you wonder how to add apps to Vizio Smart TV? Let’s explain the process in the simplest possible manner of downloading apps on Vizio smart TV for you here.

● Check to See if the Remote Control is Working.

Check to make sure that the remote control is working. If you can’t get the volume up and down, check the batteries in your remote control. Be sure you are pointing the remote control directly at your TV.

This is because sometimes this can cause problems controlling it from long distances. You may also want to consider replacing them if they have been used for a prolonged period without being replaced. Or if they have been exposed to extreme cold or heat.

Check Remote Control

Also, if you want to fix the Vizio remote not working, let’s know the causes, and then fix the problem that stops your remote from working properly.

● Make Sure That the TV Volume Settings Are Not on Mute.

Try to fix it by going to your TV’s settings and turning off the mute function. If this doesn’t work, try resetting your remote control. If that doesn’t work, you may have an issue with your remote, or it may be broken.

To fix this issue, press Mute on your Vizio remote control and make sure that it isn’t on mute. Then check whether the volume is set correctly in your Vizio TV settings menu. Also, please check if there is a lock on one of the buttons.

In addition, if your Peacock TV is not working, here are the fixes to try. These solutions will get your favorite source of entertainment to work in no time.

● Check the Volume Control Lock

The Volume Control Lock may be enabled if you’re experiencing Vizio TV Sound not working problems. This feature can be found under Settings > System > Advanced > Volume Control Lock.

If you find that this setting is turned on, try turning it off and then restarting your device. If this doesn’t help, try resetting your TV by unplugging it from its power source for 30 seconds before plugging it back in again.

The Volume Control Lock is under Settings > System > Advanced > Volume Control Lock. You can toggle this lock-off if you wish to control sound levels directly from within apps or other inputs without going into a separate menu to adjust volume levels.

● Make Sure That the Software on Vizio TV is Up-to-Date.

To check that your Vizio TV is up-to-date and has the most current version of its software, press the Menu button on your remote.

Then select System > Device Info. You are good to go if a recent date appears in Software Version! Otherwise, you’ll need to update the firmware manually.

● Check That the HDMI Cable is Functioning Correctly.

Another method to fix the Vizio TV volume not working involves ensuring that the HDMI cable is functioning correctly.

Check for any damage in the cable or at its ends and replace it if there is any. If it’s not damaged, check that the wires’ ends are fitted correctly into their ports on both devices.

Next, test whether each port works individually with another device, such as a laptop or gaming console.

If this does not work, try switching your HDMI port for another one. But be aware that some devices require specific ports. So check first before changing yours!

Check HDMI Cable

● Check if SAP or MTS is Enabled on Your TV.

If you see the SAP or MTS message on your TV screen, there is a problem with the HDMI protocol. The SAP and MTS features of the HDMI protocol are enabled by default, but they can be disabled if necessary.

To check this setting: turn off your Vizio TV. Then unplug its power cord from an electrical outlet or wall outlet. Then reconnect it to power once again. Unplug all connected devices except one HDMI cable connecting to your Vizio TV.

And then plug in only one HDMI cable at a time. Do this until you find which port works best for watching movies or shows over tablets/phones etc.

Check if SAP or MTS is Enabled on Your TV

● Check if the Volume on the Satellite Box is Above Zero.

If your Vizio TV Sound is not working, you should check the volume on your satellite box. Make sure it’s not muted or set at zero.

If it is, try to reset it. You can contact your cable provider for help with this problem if that doesn’t work.

● Check That No Headphones Are Plugged into Your TV’s Headphone Jack Port.

You will have to check to see if headphones are plugged into the port on your TV’s headphone jack. If they are, unplug them. If they’re not plugged in, check that the sound is not muted. Unmute it by using your remote or pressing a button on a universal remote (if you have one).

If that doesn’t work, check your volume control lock. This setting can prevent accidental changes to your volume level. For example, if you’re watching something with headphones and don’t want those around you to hear what’s happening on screen!

● Try Unplugging Everything

Unplugging the TV and letting it sit for a few minutes can often work to reset and fix the Vizio TV volume not working issue. This will help reset your Vizio TV to factory settings and clear any problems causing this issue.

If you have multiple devices plugged into your Vizio TV, try unplugging everything except the power cord and see if the volume still doesn’t work. If it does, you’ll need to look at other potential causes of this problem.

Unplugging Everything

● Factory Reset Vizio TV

In this section, we’ll discuss how to perform a factory reset of your Vizio TV. This will run through the setup process again and may fix any software issues causing the Vizio TV no sound problem.

First, ensure your TV is turned off (if it’s already on, press and hold the power button until it shuts off). Then press & hold down the power button for 10 seconds.

Next, press the power button once more to turn your Vizio TV back on. Then enter a password promptly if you haven’t previously set one up for your Vizio SmartCast™ device. The default password for all Vizio SmartCast™ devices is “0-0-0-0“.
