Fix: No Sound After Windows Update (Windows 11 & Windows 10 Guide)

If your computer suddenly has no sound after a Windows update, the issue is usually caused by a driver conflict, incorrect audio settings, or a playback device change. Windows updates sometimes install a generic audio driver that replaces the original driver from your computer manufacturer.

Fortunately, restoring sound usually takes only a few minutes. This guide explains step-by-step solutions to fix sound problems after a Windows update in both Windows 11 and Windows 10.

Quick Fix: No Sound After Windows Update

If your computer has no sound after a Windows update, the problem is often caused by an incorrect audio driver, a changed playback device, or disabled audio services. To fix it, first check your default audio output device in Sound Settings, then run the Windows audio troubleshooter. If the issue continues, reinstall or update the audio driver through Device Manager. In many cases, installing the correct Realtek Audio driver or Intel Smart Sound Technology driver restores sound immediately.

Why Sound Stops Working After a Windows Update

A Microsoft Windows Update can change several system components that affect audio.

Common causes include:

• Windows installs the wrong audio driver
• The default playback device changes
• Windows Audio services stop running
• Audio enhancements conflict with the new update
• System files become corrupted
• Drivers become incompatible with the latest Windows build

Most of these issues can be resolved by reinstalling the correct audio driver or adjusting sound settings.

Fix 1: Restart Your Computer

It may sound simple, but restarting your system can resolve temporary driver conflicts caused by Windows updates.

1. Click Start
2. Select Power
3. Click Restart

Fix 10: Repair Windows System Files

If Windows system files were damaged during the update, you can repair them using System File Checker.

Steps

1. Open Command Prompt (Admin)
2. Run:

sfc /scannow

3. Wait for the scan to complete
4. Restart your PC

This tool repairs corrupted Windows system files.

Fix 11: Use System Restore

If the problem started immediately after a Windows update, restoring your system may solve the issue.

Steps

1. Search for Create a Restore Point
2. Click System Restore
3. Select a restore point created before the update
4. Follow the prompts

This reverses system changes without deleting personal files, in some cases System Restore may not be enabled, this can happen if disk space is low or the System Restore has been manually disabled.

When to Download Audio Drivers Manually

If none of the solutions work, installing the latest driver directly from the manufacturer is often the best option.

Common audio drivers include:

• Realtek HD Audio Driver
• Intel Smart Sound Technology Driver
• AMD HD Audio Driver
• NVIDIA HDMI Audio Driver (more so on Windows 7 systems)

Installing the correct driver ensures compatibility with the latest Windows updates.

Prevent Sound Problems After Future Windows Updates

To avoid audio issues in the future:

• Install official drivers from your device manufacturer
• Create system restore points before major updates
• Keep your system drivers updated
• Disable problematic automatic driver updates

These steps help prevent driver conflicts when Windows installs new updates.
