If your Dell Vostro 5620 laptop has no sound coming from the speakers, or your headphone jack is not working, you are likely facing a driver issue or a device configuration problem. The Vostro 5620 uses a Realtek ALC3254 audio chipset, and when audio stops working, it is usually because the driver needs updating or reinstalling. This guide will walk you through the most effective fixes.
Why Dell Vostro 5620 Audio Output Is Not Working
Realtek Audio Driver Missing or Outdated
The Realtek ALC3254 audio driver is essential for sound output on your Vostro 5620. If this driver becomes corrupted, outdated, or is removed during a Windows 11 update, your speakers and headphone jack stop working. You might see an error code or notice that audio is completely silent even though the volume is turned up.
Audio Device Missing from Device Manager
When you open Device Manager, you may not see your audio device listed under Sound, Video and Game Controllers. This means Windows 11 cannot detect the Realtek audio hardware at all, usually because the driver is missing or the chipset driver is not installed. Without the chipset driver, audio devices remain invisible to the operating system.
Realtek Driver Showing Code 10 Error
If your audio device appears in Device Manager but shows a Code 10 error meaning the device cannot start, the driver is installed but damaged or incompatible. This error prevents the audio hardware from functioning, even though the device is recognized by Windows. Reinstalling the driver almost always fixes a Code 10 error.
How to Fix Dell Vostro 5620 Audio Output Not Working
Step 1: Reinstall Realtek Audio Driver from Dell Support
The most reliable way to fix audio issues is to get the correct driver directly from Dell. Follow these steps:
- Visit the Dell support website and enter your exact Vostro 5620 service tag or model number.
- Navigate to the Drivers and Downloads section.
- Find and download the latest Realtek Audio Driver for Windows 11.
- Also download the Chipset Driver from the same page, as audio often depends on chipset drivers.
- Disconnect any external speakers or headphones.
- Uninstall the current audio driver from Device Manager by right-clicking it and selecting Uninstall Device.
- Restart your computer.
- Install the Chipset Driver first, then the Realtek Audio Driver.
- Restart again and test your audio.
Step 2: Run Windows Audio Troubleshooter
Windows 11 includes a built-in audio troubleshooter that can automatically detect and fix many common sound problems:
- Right-click the Volume icon in the system tray at the bottom right of your screen.
- Select Troubleshoot sound problems or go to Settings, System, Troubleshoot, Other Troubleshooters.
- Let the troubleshooter run and apply any recommended fixes.
- Restart your computer after it completes.
Step 3: Check Audio Output Device Selection
Sometimes audio stops working simply because Windows has switched to the wrong output device. Open Sound Settings by right-clicking the Volume icon and selecting Sound Settings. Make sure your Realtek speakers are selected as the default output device, not an HDMI connection or USB device. Test audio by playing a video or music to confirm sound is working correctly.

Frequently Asked Questions
Why did my audio stop working after a Windows 11 update?
Windows updates sometimes replace custom drivers with generic versions that do not work properly with your hardware. After a major Windows update, visit the Dell support website and download the latest Realtek and Chipset drivers for your Vostro 5620 model. Installing these Dell-provided drivers restores full audio functionality.
What is the difference between the Audio Driver and the Chipset Driver?
The Chipset Driver enables communication between Windows and your hardware components, including audio hardware. The Audio Driver specifically controls the Realtek ALC3254 sound card. Both are necessary for audio to work correctly. Always install the Chipset Driver first, then the Audio Driver for best results.
Can I use audio from HDMI or USB instead of my speakers?
Yes. If your Realtek speakers are not working but you have a monitor with HDMI or USB speakers, you can switch audio output to those devices in Sound Settings. However, fixing the Realtek driver is recommended so you have full audio options available on your laptop at all times.
Should I reinstall Windows to fix audio issues?
No. Reinstalling Windows should be your absolute last resort. Audio issues are almost always fixed by reinstalling drivers. Try downloading drivers from Dell support, running the Windows troubleshooter, and checking your output device selection first before considering a Windows reinstall.
Conclusion
The Dell Vostro 5620 audio issue is frustrating, but it is fixable in nearly all cases by reinstalling the Realtek driver and Chipset driver from Dell support. Start with the Dell drivers, run the Windows audio troubleshooter, and verify your output device is set correctly. After these steps, your speakers and headphone jack should work perfectly again.
