Common Causes

Several factors could lead to your LG monitor's built-in speakers refusing to play sound. Understanding the common causes can assist in pinpointing the issue more quickly. Here are some typical reasons:

Now, let’s dive deeper into solving the issue with a step-by-step troubleshooting guide.

Step-by-Step Troubleshooting

Check Physical Connections

1. Inspect Cables: Ensure all cables, especially the HDMI or audio cables, are securely connected and in good condition. Sometimes, an overlooked loose cable can be the culprit.

1. Set Monitor as Default Playback Device:
2. Right-click the sound icon on the taskbar.
3. Select 'Playback devices.'

4. Choose your LG monitor from the list and set it as the default device.

Update or Reinstall Drivers
