1- No built-in Speakers

Many LG monitors do not have built-in speakers and therefore are unable to produce sounds, which may disappoint some users who wish to listen to audio from their monitor. 

However, it is important to keep in mind that most of these monitors are designed for use with external speakers or sound systems in order to provide the user with the best listening experience. 

If you have an LG monitor and wish to connect speakers to it, there are a few different ways to do so. 

The first option is by using the audio out port located on the back of the device which can be used to plug headphones directly into it or into the speaker system using auxiliary cable with a 3.5mm jack connection. 

Another alternative is via Bluetooth connectivity where one can stream music wirelessly from their phone or other compatible device.

2- Desired Audio Source

When troubleshooting an LG monitor without sound, ensure there is a speaker present in your hardware. 

After confirming the presence of a speaker, you’ll want to check what audio source is selected on your PC. 

As most times this will be the cause of a monitor not having sound if it isn’t set as the default audio source. 

To change your audio source go to your computer’s sound settings and select the monitor from the list of available sources after which you can test whether you can hear anything coming out of it. 

If you are still having difficulties getting any sounds from your LG monitor then it is best to check for an Audio cable connection.

3- Bad Audio Cable

One of the causes for LG monitor sound not functioning could be a faulty audio cable. 

A faulty audio cable may refer to a range of issues, including bad connection or one that has become loose due to wear and tear, frayed or broken strands in the wiring, poor-quality cables.

 For determining if this is what is causing your LG monitor sound not working, you must examine the audio cable for signs of damage or loose connections and then test it with an alternate source. 

If everything checks out fine with the wire, you might need to try other options.

4- Defective Audio Card

An audio card, also referred to as a sound card, is an internal component found inside most LG monitors that processes incoming and outgoing sound signals. 

A defective audio card can be the reason for the occurrence of LG monitor sound not working if it is damaged or has a physical defect. 

In order to determine whether there is a problem with the audio card in your LG monitor, you should check if there is a separate audio card installed or if the LG monitor has an integrated one. 

If there is a separate audio card installed, remove it and replace it with another one to see if the issue of no sound from your LG monitor gets resolved.

There are several factors that cause sound issues on your LG monitor. 

One of them is related to the system audio settings, as most LG monitors come with in-built speakers, which allow users to adjust volume levels accordingly through their operating systems. 

If you find that the volume is set too low on your LG monitor, it may result in all sounds getting muted completely. 

Before fixing any potential sound issue on your LG monitor, ensure that both its volume control and operating system audio settings are checked and adjusted accordingly.

Here’s a tip: Before you start solving any kind of sound problem on your LG monitor, make sure that both its volume control and the operating system audio settings are checked and adjusted first.

Loudness Equalization settings is a feature that LG monitors offer their users to adjust the sound output levels according to whatever content they are viewing.

7- BIOS Audio Settings

BIOS Auditory Settings pertain to the audio settings that can be adjusted in the Basic Input/Output System (BIOS) of a computer. 

This setting can be utilized to adjust sounds such as speaker volume, mic level, and sound card settings.

 If you are experiencing difficulty with your LG monitor sound, it is likely due to an incorrect BIOS Auditory Setting. 

To resolve this issue, open the BIOS by pressing F1 or F2 during system startup and then check your audio settings. 

Adjusting the auditory settings in BIOS may also become necessary if you have recently installed a new sound card or other audio device. 

In some instances, the audiological settings might need to be changed manually because they may not get detected by the BIOS automatically. 

Make sure before making any changes that all selections for your LG monitor sound node within BIOS are correct and updated.

 Make a note of the kind of driver listed there (for example Realtek or AMD). 

Once you know what type of driver you have, search online for its latest version and download and install it on your device. 

Restart your PC afterwards and check if everything is now working fine with the sound on the LG monitor.
