Why does my Vizio sound bar keep getting louder?

Short answer: Your Vizio sound bar keeps getting louder due to bad cable connections, interference from other devices, a remote control problem, physical damage, a power surge, or an audio setting issue.

The most likely cause of your Vizio soundbar’s ineffectiveness is a malfunction within the device itself. There has been a reported issue with the volume increasing on its own on Vizio sound bars.

Having the level increase unexpectedly when you’re in the middle of a movie or song may be really annoying. Most of the time, the device to which a Vizio soundbar is attached is to blame, or there is interference from another source. The hardware itself, however, could be the source of the issue.

Several factors could cause this issue with your Vizio sound bar.

Reason 1 – Faulty cable connections

The volume level may increase quickly if the sound bar’s connection to the TV is incorrect. A defective cable, connector, or port can lead to this problem. Inspect these connections and cables for loose wires or physical damage if you feel they are at the root of your problem.

Reason 2 – Interference from other gadgets

The soundbar may not be operating correctly if there are wireless signals being intercepted from it by nearby objects. These kinds of issues are frequently brought on by electronic devices such as wireless routers, mobile phones, and baby monitors. If you think this might be the problem, try relocating the other electronics further from the soundbar.

Reason 3 – Issue with remote control

It’s possible that the volume rise was caused by the sound bar’s remote. Bizarre behavior from the sound bar may be the result of a defective or malfunctioning remote control.

Reason 4 – Physical damage

Some users have complained that the level on their Vizio sound bar increased unexpectedly after experiencing physical damage. A fall, a bump, or even just a spill could have brought this about.

Reason 5 – Power surge

Whenever a power surge hits, it has the potential to harm or destroy electronic items that are linked to the source of the surge. This includes a Vizio sound bar, which may be one of the reasons why the volume keeps increasing by itself.

Reason 6 – Audio setting

It is also possible for the audio settings on a Vizio soundbar to be incorrectly configured, in which case the soundbar will not provide the necessary volume. As a result, you should verify the audio settings of the device.

Fix: Vizio Sound Bar volume goes up by itself

The Vizio soundbar is a convenient way to boost the volume of your external devices without breaking the bank or spending too much time setting up your system, but it is not immune to the usual gadget issues, like the volume increasing on its own.

Let’s look at how to solve this problem now that we have a better understanding of the factors that could have contributed to its occurrence.

Method 1 – Restart Soundbar

If the issue just emerged, a simple restart could be the answer. Although it may seem like a no-brainer, often simply restarting devices is all that’s needed to fix a wide range of issues.

Step 1- Find your sound bar’s power cord and remove it from the wall outlet.
Step 2- Please hold on for a short while, usually between 20 and 30 seconds.
Step 3- Reconnect the power source to the wall socket.
Step 4- You may power up your sound bar by either pressing the button labeled “power” or by using the remote control.

Method 2 – Set the SoundBar’s Input Correctly

When the volume on your Vizio soundbar keeps increasing on its own, checking to make sure it’s connected to the right input is one of the first places to look. If you want to play audio from a source other than the soundbar’s internal speaker system, you can change the soundbar’s input settings to match.

Step 1- Turn on the television and select a program or movie to watch (so there is audio playing).
Step 2- To activate the soundbar’s front-facing flashing lights, press and hold the “Input” button.
Step 3– This will begin what is known as an “Auto Input Search.”
Step 4- The soundbar will cycle through all the inputs until it finds the one the TV is connected to, indicated by the flashing lights on the front.

Method 3 – Use a different cable

If your Vizio soundbar’s volume keeps increasing by itself, swapping out the cable may fix the problem. It’s possible that the cable you’re using to connect your soundbar to the device that you wish to play sound from is broken or not functioning properly, which could result in subpar audio quality or even the absence of sound altogether.

Try switching to a different cable, or trying a new sort of cable altogether; for instance, if you’re using an HDMI cable, try switching to an optical cable or a 3.5 mm audio cable. There’s a chance that the device you’re trying to connect has more than one port, and that one of those ports is specifically designed to work with the cable you’re trying to use.

Ensure that your new cable works with both your soundbar and the device you intend to connect it to.

Method 4 – Reduce Interference

After trying a variety of cables and inputs, if the volume on your Vizio soundbar is still going up by itself, another potential option to explore is getting rid of any gadgets that could be causing interference.

The signal that is sent between your soundbar and the device that you are attempting to play sound from can be disrupted by interference from other devices, which can result in poor audio quality or even the complete absence of sound.

It is recommended that you position any devices that emit a wireless signal away from the Vizio soundbar, as they may produce interference of this kind. Baby monitors, wireless routers, and cell phones are all examples of typical electronic devices that might generate interference.

Method 5 – Update firmware

Step 1- In the Vizio SmartCast app’s settings menu, select “System” and then “Check for Updates.”
Step 2– If you want to reaffirm your decision to look for updates, select “Yes.”
Step 3– When a software update is available, the soundbar will automatically turn itself off. The new firmware will be instantly downloaded and installed.
Step 4- It may take up to 30 minutes for the update to finish. Be aware that while the update is being deployed, your connection from the SmartCast app to the sound bar will be severed.

Method 6 – Deactivate SRS TruVolume

Although using this function generally results in an improved audio experience, there is a possibility that it will interfere with the configuration settings of an external device.

An incompatibility between the source material and the TV’s SRS TruVolume or other advanced audio settings could be to blame.

The following procedures need to be carried out in order for you to disable this function:

Step 1- Enter the Main Menu.
Step 2- Proceed to the Audio Settings menu.
Step 3- Navigate to the Advanced Audio menu.
Step 4- Deactivate SRS TruVolume.
