How to fix Vizio TV sound not working?​

Restart Vizio TV (power cycle)​

Although this method is simple, sometimes it is the most effective fix. Power cycling your Vizio TV and then restarting it can fix the problem of no sound on your Vizio TV.

The key to this method is to perform a soft reset (power cycle) on the TV, so we need to unplug the TV instead of just turning it off with the remote control.

Please follow the steps below to restart your Vizio TV.

1. Unplug the Vizio TV from the wall outlet.

2. Press and hold the power button on the TV for about 5 seconds.

3. Wait for more than one minute.

4. Reinsert the power cable into the outlet.

5. Turn on your Vivio TV and check that the sound is working.

Note: Please be patient for at least one minute or more after unplugging, as this will allow time for the Vizio TV to power cycle and refresh the settings.

You can have your TV go through the power cycle process using the menu options on some Vizio models:

1. On your TV remote, press the Menu button. (Check how to fix the Vizio TV menu not working)

2. Select System, then Reset and Admin.

3. Choose Soft Power Cycle.

4. After that, the TV will shut down and restart on its own.

Check your Vizio remote​

Usually, we use the remote control to control the volume of the TV, but if your Vizio remote runs out of power or malfunctions, you will probably face the problem of no sound on your TV.

You can press the volume button on the remote control to check if the TV responds to the remote control. If the remote control runs out of power, replace the batteries with new ones promptly.

If your remote control has malfunctioned, you need to buy a new one.

Ensure your Vizio TV is not Muted​

You may have accidentally set your TV to mute without realizing it, in which case your TV will not make any sound.

You can try to cancel the Vizio TV mute setting by pressing the mute button on the remote control.

Check Vizio TV Volume​

If your Vizio TV is not unmuted, but still has no sound, it may be because the current volume is zero. You need to adjust the volume of your TV using the remote control.

1. Press the Up button on the Vizio remote. Or the "+" button on the volume button.

2. Turn up the volume of your TV to a range where you can hear the sound.

3. If you turn the TV volume up but still cannot hear the sound, please continue reading to troubleshoot the problem.

Check your HDMI cable​

HDMI cables are critical in transmitting audio and video signals to televisions.

If the HDMI cable connecting your TV to an external device is faulty, your Vizio TV may experience volume issues.

If you can see video but not hear audio on your TV, it is very likely that your HDMI cable is broken.

You can replace the HDMI cable with another one to connect your device and make sure all cables are firmly plugged into the TV's port. This is because loose or damaged cables can cause interference with sound transmission.

Make sure the TV speakers are turned on​

If you are using your TV's built-in speakers instead of external audio, you can check if the speakers are turned on.

1. Turn on your Vizio TV and press the Menu button on the remote control.

2. Scroll to select Audio or Audio Settings.

3. Check if the option next to the TV Speakers setting is "On", if not, turn it on.

Check the volume of the set-top box​

If you are using a cable or satellite box, it will transmit video and audio to your Vizio TV. Therefore, the volume setting on the set-top box also affects how the sound works on your Vizio TV.

You can use your remote control to check if the set-top box is muted. After unmuting it, increase the volume of the set-top box to a level that you can hear.

Check if your Vizio TV is SAP enabled​

SAP stands for Assistive Audio Programming, which is usually a second audio stream included in a TV show that can be used to listen to a video on your TV in a language other than the original.

If you prefer to listen to the show in its original language, you can quickly disable SAP. Popular TV audio menu labels include SAP, AUDIO SELECT, B-AUDIO, MTS, MS, and MENU.

You can follow these steps

1. Press the Menu button on the Vizio remote control.

2. Select "Audio" in the list.

3. Select SAP or MS.

4. You can turn it off.

You may be required to choose "Stereo" or "Mono" from the menu, one of which will be SAP.

Turn off DTS TruSurround on Vizio TVs​

There is feedback from Vizio users that DTS TruSurround conflicts with TV shows may be the cause of Vizio TV sound not working. You can turn off a similar advanced audio setting.

Please follow these steps to turn off DTS TruSurround on Vizio TV.

1. Navigate to the Main Menu.

2. Navigate to Audio Settings.

3. Navigate to Advanced Audio.

4. Disable DTS TruSurround.

Check if the headset is plugged into the TV​

If you forget to unplug the headphone device connected to the audio jack of the Vizio TV, the audio from the TV will be transmitted to the connected device.

In this case, you will definitely not be able to hear the sound of the TV if you are not wearing headphones.

You need to disconnect the device from the audio jack and then use the remote control to raise the volume of the TV.

Update the software on Vizio TV​

2. Go to System and select Check for Updates.

3. The TV will search for available updates, and if so, you can confirm the installation.
