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.

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.

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:

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:

  • 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.

  • Once done, reboot the PC to apply changes.
