If your Windows computer suddenly loses audio, the Realtek sound driver is often the cause. Problems such as no sound, distorted audio, missing playback devices, or Realtek Audio Console not opening usually indicate corrupted, outdated, or incorrectly installed audio drivers.
This guide explains the common causes and offers proven troubleshooting solutions. Before trying more advanced fixes, begin with a full driver update using Driver Sentry, ensuring Windows loads the correct and most compatible version.
Update Realtek Sound Driver Using Driver Sentry

Download and Install:
Click the "Download" button to download the software package.
Install it on your Windows PC.
Run Scan:
Launch the application and click the "Scan" button.
The software will perform a deep analysis of your system, focusing on multimedia and core system components.
Execute Update:
Once the scan completes, look for Realtek High Definition Audio or Realtek Audio Driver in the driver list.
Click the "Upgrade" next to the Realtek item. Wait while Driver Sentry downloads and installs the correct Realtek audio driver version.
Restart your pc:
Restart your computer to apply the installation.
Test the sound again to confirm the issue is resolved.
If the driver update does not fully restore your audio, continue with the additional fixes below.
Common Causes of Realtek Sound Driver Problems
Several issues can interrupt Realtek audio on Windows:
Corrupted or outdated Realtek audio driver
Windows Update installing the wrong driver
Disabled playback device
Conflicts between Realtek and Windows audio services
Incorrect BIOS or hardware settings
Damaged audio ports or faulty peripherals
Fix 1: Restart Windows Audio Services
Audio services must run correctly to deliver sound.
1). Press Windows + R, type "services.msc", and press Enter.
2). Find these services:
Windows Audio
Windows Audio Endpoint Builder
3). Right-click each one and select "Restart".
4). Make sure their Startup Type is set to Automatic.
5). Reboot the PC and test audio again.
Fix 2: Reinstall Realtek Audio Driver Manually
If the driver is corrupted, reinstalling it may resolve the issue.
Right-click the Start menu and open Device Manager.
Expand "Sound, video and game controllers".
Right-click "Realtek High Definition Audio" and select "Uninstall device".
Check "Delete the driver software for this device" if available.
Restart your computer.
Windows will attempt a reinstall, but if sound is still missing, run Driver Sentry again for a clean installation.
Fix 3: Check Playback Device Settings
Sometimes Windows selects the wrong output device.
1). Open Settings > System > Sound.
2). Under Output, choose the correct device such as:
Speakers (Realtek High Definition Audio)
Headphones
3). Click "Device Properties" and ensure it is not disabled.
4). Test the sound.
Fix 4: Disable Audio Enhancements
Enhancements may cause audio distortion or silence.
Right-click the speaker icon and choose Sound settings.
Select the output device.
Open "Advanced settings".
Disable all enhancements.
Restart and test again.
Fix 5: Roll Back Recent Updates
Realtek drivers are sensitive to forced Windows updates.
Open Device Manager.
Expand "Sound, video and game controllers", right-click "Realtek High Definition Audio".
Select "Properties" > "Driver" tab.
Click "Roll Back Driver" if available.
Restart the system.
Fix 6: Run Windows Audio Troubleshooter
Microsoft's built-in troubleshooter can detect configuration issues.
Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters.
Find "Playing Audio" and click "Run the troubleshooter".
Follow the on-screen instructions.
Fix 7: Check Physical Audio Ports and Devices
Hardware connection issues can also mimic driver failure.
Test headphones or speakers on another device.
Try different audio ports.
Remove adapters or splitters.
If audio works externally but not on your PC, reinstall the driver using Driver Sentry.
Fix 8: Reset BIOS Audio Settings
Incorrect BIOS settings may disable onboard audio.
Restart the system.
Enter BIOS using F2, Delete, or Esc (varies by brand).
Locate "Onboard Audio", "HD Audio", or "Realtek Audio" in the settings.
Ensure it is set to "Enabled".
Save and exit.
