Users may encounter a "Not Plugged In" error with Realtek High Definition Audio. This article offers simple methods to resolve the issue.
1. Update the Drivers
Outdated or corrupted drivers can cause the "Not Plugged In" error. Updating the audio drivers can effectively fix this problem. Using Driver Sentry to automatically detect and update drivers saves time and prevents errors during installation.
Download the latest version of Driver Sentry and install it. Open the software, click "Scan", and identify outdated or missing drivers.
Locate the audio driver in the results list and click "Upgrade".
Restart your computer after the update to ensure the changes take effect.
2. Check Hardware Connections
Ensure that the headphone or speaker plug is firmly connected to the computer's audio jack.
If using the front panel jack, try connecting to the rear audio jack to rule out front panel issues.
Test the headphones or speakers on another device (e.g., a smartphone) to confirm they are functioning correctly.
If the device works on other systems, the issue may lie with the computer's audio jack.
Clean the audio jack using a dry cotton swab or compressed air to remove dust or debris that might affect the connection.

Double-click to open the Realtek High Definition Audio Manager.
Click the "Folder" icon (usually labeled as Advanced Settings).
Check the box for "Disable Front Panel Jack Detection", then click "OK".
Reconnect your headphones or speakers and check if the device works.
5. Run Audio Troubleshooter
