Vizio Soundbar No Sound: Causes & Fixes

If you are not keen on getting an entire sound system, soundbars are a great way to amplify the audio from your TV set or other source devices.

Vizio soundbars are a group of high-quality speakers that are sleek, and emit theater-grade sounds, that any audiophile would appreciate. Plus, you can purchase them without drilling holes in your pocket.

However, as common to most electronic devices, Vizio soundbars are prone to technical issues, one of which is the problem of no sound. In this guide, we will walk you through the possible causes of no sound coming from your Vizio soundbar, as well as their quick fixes.

Vizio Soundbar No Sound: Possible Causes

There are several reasons as to why your Vizio soundbar isn’t producing any sound. Most times, the root cause could stem from the connection system, or interfering devices on the network. At other times (though occasionally), hardware faults from the soundbar itself, could be the issue. Let’s explore some specific causes below: 

• No Power 

For your Vizio soundbar to produce sound, the device has to be powered on. When the soundbar is powered on, you will notice a light at the center or left-hand side of the device. If you don’t notice any lights, there is no power. This issue could arise from the connection of the power cable, or the power outlet. 

• Muted/Low Volume 

Ensure that the volume isn’t muted on the source device. Also, ensure that the volume is turned up. For some TV models, the soundbar can produce audio, provided the volume level on the TV is not at 0. For others, you might be required to turn the volume of the TV up, to get satisfactory sound from the soundbar. 

• Wrong Input/Output Settings 

Different TV models come with a variety of ports. While most of them are input ports, you need to connect the soundbar to an Audio Out port, for it to produce sound. There would be no sound if the soundbar is connected to any other port. The soundbar also has to be connected to the input that the source device is plugged into. 

• Weak Connection

To avoid interruptions in the sound transmission, there has to be a strong and stable connection between the soundbar and the source device. A weak connection between both devices would result in the soundbar frequently going out of sync with the sound device, and this leaves you unable to enjoy your favorite songs, shows, or movies. 

There is also a situation commonly referred to as Bluetooth traffic. This happens when there are too many devices connected to the network, causing network overload. This often results in sound interference. 

• Remote Problems

Remote controls offer convenience, as a result, most users hardly use the buttons on electronic devices. Once they attempt to operate the device using the remote control system, and it doesn’t work, some run off with the conclusion that the device has developed a fault, or that there is a problem with the connection. 

However, in some cases, there might not be an issue with the connection or any of the devices in the system. The problem instead, could be from the remote control. 

• Presence of Interfering Devices 

Any device capable of sending a wireless signal can cause interference to the audio produced by your Vizio soundbar. These devices commonly include wireless routers and cell phones. 

• Might Need a Soft Reset

In some cases, the soundbar might require a soft reset. This is often the case when the device has run for hours on end, without being disconnected from the power source. This issue is often characterized by varied forms of malfunctioning. 

• Might Need a Factory Reset

At other times, the soundbar might need a factory reset. Factory resetting your Vizio soundbar would result in a permanent loss of the settings stored on the device. Step-by-step instructions on how to carry out the factory reset will be provided below. 

Vizio Soundbar No Sound: How to Fix

If any of the likely causes listed above relate to your situation, you can easily troubleshoot the problem by carrying out any of these simple steps: 

• Ensure Power Supply

Ensure that power is being supplied to the soundbar, by confirming the appearance of light either at the center or left-hand side of the device. Also, ensure that the power cable is tightly and securely connected. You can also confirm if the wall receptacle is functional, by connecting another gadget, like a lamp, for instance. 

• Adjust Volume Levels

Depending on your TV model, be sure to adjust the volume levels on both your TV set/source device and the soundbar. Also, ensure that the audio is not muted on any of the devices. You can easily correct this, with the Mute button on the remote control. 

• Ensure Proper Input/Output Settings

Ensure that all audio cables are securely connected to their respective ports. This includes the HDMI cables, and optical cables, as the case may be. The soundbar cable should be connected to the Audio Out port on the TV. 

Also physically inspect the different cables occasionally, for any sign of wear or defect. Ensure to disable the internal speakers feature on the TV as well. 

• There Should Be a Stable Connection

Ensure a strong and stable connection between both devices in the system. Disconnect other wireless connection devices that might congest the network, and allow only a reasonable distance between the source device and the soundbar. 

• Ensure Remote Functionality

To check if the problem is from the remote control, you can attempt to operate the soundbar using the buttons on the device. If the buttons on the device get the job done, that should immediately tell you that there is a problem with the remote control. Low battery levels are often the cause of poor remote functionality, so be sure to change the remote batteries regularly. 

• Remove Interfering Devices

All interfering devices that function via wireless connection, should be moved out of range, from the soundbar and source device. 

• Carry Out a Soft Reset

If you are having problems with your Vizio soundbar, a soft reset is a good step to try. It is a quick and easy way to fix many common problems, without having to erase your custom settings. 

To soft reset a Vizio soundbar, follow these steps:

1. Unplug the soundbar from the power outlet.
2. Wait for 30 seconds.
3. Plug the soundbar back into the power outlet.
4. Turn on the soundbar.

• Carry Out a Factory Reset

To factory reset your Vizio soundbar, follow these steps:

1. Turn on your Vizio soundbar.
2. Press and hold the Bluetooth and Volume Down buttons simultaneously for five seconds.
3. All the lights on the soundbar will flash three times. This indicates that the reset is complete.
4. Release the buttons.

Note: A factory reset will erase all of your custom settings, including volume levels, sound modes, and EQ settings. You will need to reconfigure these settings after the reset.
