It provides ultra visual quality, high dynamic contrast, wide color spectrum, up to 240Hz screen refresh rate, 1ms motion blur reduction, 21:9 widescreen, etc. However, some users are reporting that the LG Ultragear Sound is not working or audio crackling issue, or the sound cutting out issue.

According to multiple reports on the Reddit forum, several unfortunate LG Ultragear monitor users are getting affected by the sound not appearing issue quite often.

Fix: LG Ultragear Sound Not Working or Audio Crackling, Cutting out

It becomes quite frustrating for the users to deal with such an issue because it ruins the gaming experience in several ways. Luckily, here we’ve shared a couple of possible workarounds for you that should come in handy. So, without further ado, let’s jump into it.

1. Confirm the Model Number and Its Features

The chances are high that your specific model number may not have the integrated speakers built-in or just have an audio output port to connect headphone/speakers externally. If you have kept your monitor’s manual book then make sure to check that properly.

2. Check Sound Settings

Make sure to cross-check whether your audio device isn’t muted and hasn’t been disabled. You can follow the steps below to do so:

• Right-click on the Speakers icon on the taskbar > Select Open Volume Mixer.
• Here you’ll find out the volume icon and volume level of the connected monitor.
  • Just unmute the volume icon and increase the audio level to high so that you can hear audio properly from the monitor.
• If you don’t see Speakers, select Show hidden icons to check there.
• You’ll see a set of volume controls for your devices. Ensure the specific monitor audio isn’t muted.
• If in case, the audio is muted, just click on ‘x’ next to the volume control. Then follow the steps below to unmute it:
• Select the Volume control > Adjust the desired volume level.
• Click on the Unmute speakers icon > Check your device properties so that your device has not been disabled.
• Press the Windows + I keys to open Settings > Click on System > Click on Sound.
• Under the Advanced section, select More sound settings > Select the Playback (output) or Recording (input) tab.
• Choose your LG Ultragear monitor device > Select Properties.
• Now, go to Device usage > Select Use this device (enable) from the output and input devices.
• Make sure to apply changes by clicking on Apply and then OK > Once done, reboot the PC.

3. Update Audio Source

It’s also recommended to update the audio source on the Windows computer because an incorrect audio source will trigger multiple issues with the sound not working. You can follow the steps below to do so:

• Click on the Sound/Speaker icon at the bottom right side of the taskbar.
• Click on the arrow icon next to the Speaker option > Here you’ll see the audio output option.
• Now, click on the particular monitor that you’re connected to the PC.
• Finally, the sound should start coming out of the monitor’s integrated speaker. Make sure to turn up the volume and increase the level.

4. Set LG Ultragear Monitor as Default Audio Device

• Press the Windows + I keys to open Settings > Click on System > Click on Sound.
• Under the Advanced section, select More sound settings > Select the Playback (output) tab.
• Choose your LG Ultragear monitor device > If the monitor isn’t set as a default audio device then just click on it to highlight it.
• Then click on the Set Default button > Click on OK and select Apply to save the changes.
• Once done, make sure to reboot the PC to apply changes.

If in case, you don’t see your monitor listed in the Playback tab then it might be disabled or hidden. To make it visible:

• Just right-click on any blank area then select Show Disabled Devices and Show Disconnected Devices.
• Once it appears, you can set it as the default device easily.

5. Update Audio Drivers

Try updating audio drivers on the Windows PC if you’re assuming that your audio driver has been outdated or corrupted. Sometimes an outdated or corrupted sound driver can cause multiple issues with the audio output or sound crackling. To update it:

• Right-click on the Start Menu to open up the Quick Access Menu.
• Click on Device Manager from the list.
• Now, double-click on the Sound, video and game controllers category to expand the list.

• Once done, make sure to reboot your computer to change the effects.

6. Check for Hardware Connection and Physical Damage

It’s also highly recommended to check whether your LG Ultragear monitor is properly connected to the PC or not. Sometimes loose connectivity or incorrect port connectivity can cause several issues with the sound not working issue. Whereas any kind of physical damage to the monitor’s audio port or the speakers can also trigger the same issue in most cases. Try reconnecting the audio cable to the monitor’s audio port to fix connectivity issues.

If in case, there is physical damage on the audio cable such as HDMI or DisplayPort cable or the audio cable becomes outdated then make sure to try using another cable to check for the issue again.

7. Adjust Volume Settings on Monitor

Make sure to check for the settings menu on the monitor which can be placed under the screen panel or the side panel. Just access the settings or audio settings and check if the volume is turned on and the volume level is set to high or not. If not, you can manually adjust the volume settings of the monitor using physical buttons or joystick depending on the model.

8. Enable Loudness Equalization

You can also try enabling the loudness equalization option on the Windows system by following the steps below. It may be disabled on the PC which can cause audio balancing issues from the speakers. To do so:

• Click on the Windows icon to open the Start menu > Type Control Panel in the search field.
• Open Control Panel from the search result > Select Sound.
• Now, double-click on the LG Ultragear monitor > Under the Enhancements tab, enable the Loudness Equalization checkbox.
• Then click on OK to save changes.

9. Run Audio Troubleshooter

Another thing you should do is simply run the audio troubleshooter method on the Windows system by following the steps below. It’ll basically check the potential conflicts or reasons behind such an issue so that you can perform the troubleshooting. Mostly the troubleshooter method fixes the issues automatically. To do so:

• Press the Windows + I keys to open Settings > Click on System.

• Now, follow the on-screen instructions to perform the task, and you can also select options according to your choice.
• Once done, reboot the PC to apply changes.

10. Disable Audio Enhancements

Some Windows 11 users have also reported that after disabling the audio enhancements on the system, the sound distortion issue has been fixed or reduced drastically. If the audio enhancements are enabled on your computer, try disabling them might fix the issue. To do so:

The steps to boot into the BIOS menu might vary depending on the manufacturer and model number. So, head over to the respective manufacturer’s website and search for the tutorial or user manual for the model.

12. Update Windows

Sometimes an outdated or corrupted Windows system version or build version can eventually trigger multiple issues with the audio detection as well as the sound not working.

14. Reinstall Audio Driver

Make sure to uninstall the audio driver, restart the system, and then reinstall the audio driver again on the PC to check if the problem has been fixed or not. Sometimes reinstalling the audio driver can help you to resolve the issue. It also fixes sound detection issues, sound distortion, audio cutting out, etc. To do this:
