Are you experiencing frustrating volume fluctuations with your LG soundbar? You’re not alone. Many users have reported this issue, and it can be caused by a variety of factors. In this article, we’ll delve into the possible reasons behind the problem and provide you with step-by-step troubleshooting guides to resolve the issue.
Understanding the LG Soundbar Volume Control
Before we dive into the troubleshooting process, it’s essential to understand how the LG soundbar volume control works. The volume control on your LG soundbar is typically managed by the soundbar’s internal amplifier, which receives audio signals from your TV or other connected devices. The amplifier then adjusts the volume according to the input signal and the settings you’ve configured.
Volume Control Methods
There are two primary methods of controlling the volume on your LG soundbar:
- Manual Volume Control: This method involves using the volume buttons on your soundbar remote control or the soundbar itself to adjust the volume.
- Automatic Volume Control: This method uses the soundbar’s internal circuitry to automatically adjust the volume based on the input signal.
Possible Causes of Volume Fluctuations
Now that we’ve covered the basics of the LG soundbar volume control, let’s explore the possible causes of volume fluctuations:
1. Incorrect Audio Settings
Incorrect audio settings on your TV or other connected devices can cause volume fluctuations. For example, if the audio output on your TV is set to “Variable” instead of “Fixed,” the volume may fluctuate.
How to Check Audio Settings
To check the audio settings on your TV:
- Go to your TV’s settings menu.
- Select “Sound” or “Audio.”
- Look for the “Audio Output” or “Digital Audio Out” setting.

Why does my LG soundbar volume keep going up and down by itself?
The LG soundbar volume going up and down by itself can be caused by various factors, including faulty remote controls, incorrect settings, or interference from other devices. It’s also possible that the soundbar is receiving signals from other devices, such as a TV or gaming console, which can cause the volume to fluctuate. To troubleshoot this issue, try checking the remote control for any signs of damage or malfunction, and ensure that the soundbar is set to the correct input mode.
In addition, check the soundbar’s settings to ensure that the auto-volume feature is turned off. This feature can sometimes cause the volume to adjust automatically, leading to the issue you’re experiencing. If the problem persists, try resetting the soundbar to its factory settings or consulting the user manual for further troubleshooting steps.
How do I reset my LG soundbar to its factory settings?
Resetting your LG soundbar to its factory settings can often resolve issues with the volume going up and down. To do this, press and hold the ‘VOL-‘ and ‘VOL+’ buttons on the soundbar simultaneously for about 5 seconds. Release the buttons when the soundbar’s display shows ‘INIT’ or ‘RESET’. This will restore the soundbar to its default settings, which may resolve the volume issue.
After resetting the soundbar, you’ll need to reconfigure the settings to your preferences. This includes setting the input mode, adjusting the volume levels, and configuring any other features you were using. Make sure to refer to the user manual for specific instructions on how to reset and reconfigure your LG soundbar model.

Check the remote control for any signs of damage, such as cracks or broken buttons. Also, try replacing the batteries or cleaning the remote control to ensure it’s functioning properly.
If you suspect that the remote control is the cause of the issue, try using the soundbar’s controls directly or using a different remote control to adjust the volume. If the problem persists, it’s likely that the issue lies with the soundbar itself, and you may need to consult the user manual or contact LG support for further assistance.
How do I disable the auto-volume feature on my LG soundbar?
The auto-volume feature on your LG soundbar can sometimes cause the volume to adjust automatically, leading to the issue you’re experiencing.

Alternatively, you can also try pressing the ‘VOL-‘ and ‘VOL+’ buttons on the soundbar simultaneously for about 3 seconds. This will toggle the auto-volume feature on and off. If you’re unsure about how to disable the auto-volume feature on your specific LG soundbar model, refer to the user manual for instructions.
Can other devices interfere with my LG soundbar’s volume?
