How to Fix Realtek High Definition Audio “Not Plugged In”

If you’re encountering a situation where your audio isn’t working and your system shows the message “Realtek High Definition Audio – Not Plugged In,” you’re not alone. This issue is common among Windows users and usually indicates a miscommunication between the hardware and software on your device. Fortunately, it’s usually easy to fix with a few troubleshooting steps.

TLDR (Too long, didn’t read)

If your computer says “Realtek High Definition Audio – Not Plugged In,” it likely means your audio jack or driver is experiencing an issue. First, check your hardware connections and try plugging into a different audio port. Update or reinstall your Realtek audio drivers and ensure that the correct playback device is set as default in your sound settings. Finally, test the playback device and audio service to make sure they’re running properly.

1. Understand What the “Not Plugged In” Message Means

Before diving into solutions, it’s important to understand what this message actually means. The error doesn’t always mean that speakers or headphones aren’t physically connected. Instead, it may indicate that your system isn’t detecting the hardware properly due to software issues, driver corruption, BIOS settings, or even a damaged audio jack.

2. Check Physical Audio Connections

Start with the basics by checking your hardware connections:

• Ensure your headphones or external speakers are properly plugged into the correct audio jack.
• Try plugging the device into another port if available.
• Inspect the cable and connectors for any visible sign of damage.

If you’re using a desktop PC, make sure to test both the front and rear audio jacks.

3. Enable and Show Disabled Playback Devices

Sometimes, Windows hides disabled or disconnected devices. To make sure everything is visible and selectable, follow these steps:

1. Right-click on the sound icon in the taskbar and select Sounds or Open Sound Settings.
2. Click on Playback.
3. Right-click in the device list area and check Show Disabled Devices and Show Disconnected Devices.
4. If your headphones or speakers appear in the list, right-click and choose Enable.

Once enabled, set the correct playback device as default to ensure that Windows uses it for sound output.

4. Update or Reinstall Realtek Audio Drivers

Outdated or corrupted audio drivers can cause the “Not Plugged In” error. Updating or reinstalling the Realtek High Definition Audio driver is a reliable fix.

To update the driver:

1. Press Windows + X and select Device Manager.
2. Expand the Sound, video and game controllers section.
3. Right-click on Realtek High Definition Audio and choose Update driver.
4. Select Search automatically for updated driver software.

To reinstall the driver:

1. Repeat the steps above up to the right-click menu.
2. Choose Uninstall device.
3. Restart your computer. Windows will attempt to reinstall the missing driver automatically.

If it doesn’t, visit your PC manufacturer’s website or the official Realtek site to download and install the correct drivers manually.

5. Check BIOS Audio Settings

Sometimes, audio components might be disabled from the BIOS, especially after system updates or configuration changes.

To verify BIOS settings:

1. Restart your computer and repeatedly press the BIOS key (often F2, DEL, or ESC) during boot-up.
2. Navigate to the Integrated Peripherals or Advanced section using arrow keys.
3. Ensure that Onboard Audio or HD Audio is set to Enabled.
4. Save and exit BIOS (usually F10), and let the computer reboot.

This solution is especially useful for newly built systems or when multiple sound cards are in use.

6. Restart the Windows Audio Service

Windows relies on several background services to manage sound, and sometimes these services can hang or stop.

To restart the audio service:

1. Press Windows + R, type services.msc, and press Enter.
2. Scroll down and find Windows Audio.
3. Right-click and select Restart.
4. Also restart Windows Audio Endpoint Builder in the same way.

This can reactivate your audio subsystem and remove the “Not Plugged In” error.

7. Test with Different Audio Devices

If all else fails, it’s time to test different headphones or speakers. If another device works fine on your system, then the original one may be defective.

Plug your current audio device into a different system (like a phone or another computer) to verify its functionality. This test will help isolate whether the issue is actually with the PC or the external device.

8. Use the Windows Troubleshooter

Sometimes the built-in troubleshooter can automatically detect and fix issues:

1. Go to Settings → Update & Security → Troubleshoot.
2. Select Playing Audio and then click Run the troubleshooter.
3. Follow the prompts and allow the system to fix any detected issues.

Conclusion

While the “Realtek High Definition Audio – Not Plugged In” error can be frustrating, in many cases it’s resolved with a little troubleshooting. By checking physical connections, updating or reinstalling drivers, and verifying system settings, users can often get their sound restored without needing professional help.

If your issue persists after trying all the steps above, it could indicate a more serious hardware issue, in which case reaching out to a certified technician or your device’s manufacturer may be the best next step.
