如果Windows更新後聲音無法工作，可按以下步驟修復(fù)：首先檢查音頻設(shè)備是否連接正常並確認(rèn)音量設(shè)置；其次運(yùn)行系統(tǒng)內(nèi)置的音頻疑難解答工具；接著在設(shè)備管理器中更新或回滾音頻驅(qū)動(dòng)；若無效可嘗試完全卸載並重新安裝驅(qū)動(dòng)；最後檢查Windows更新和可選驅(qū)動(dòng)更新。這些方法通常能解決因驅(qū)動(dòng)衝突或設(shè)置重置導(dǎo)致的音頻問題。

If your sound stopped working after a Windows update, you're not alone — this is a common issue that pops up from time to time. Updates can sometimes cause driver conflicts or reset audio settings without warning. The good news is, most of the time it's a quick fix. Let's go over some of the most effective ways to get your audio back.

Check basic audio settings first

Before diving into more technical fixes, start with the basics:

• Make sure your speakers or headphones are properly plugged in and powered on.
• Check the volume — both system volume and app-specific volume (like in the Volume Mixer).
• Ensure no other device is selected by mistake — right-click the speaker icon in the taskbar and choose "Sounds" or "Open Sound Settings," then check the playback tab for active devices.

Sometimes Windows switches the default audio device during an update, especially if you have multiple output options like HDMI, USB, or Bluetooth.

Run the built-in audio troubleshooter

Windows has a built-in troubleshooter that can detect and often automatically fix audio issues:

1. Go to Settings > System > Sound .
2. Scroll down and click "Troubleshoot" under the "Other sound options" section.
3. Let it scan for problems and apply any fixes it finds.

This tool usually catches simple issues like muted devices, incorrect defaults, or missing drivers.

Update or roll back audio drivers

A Windows update might have installed a bad driver or overwritten a working one. Here's how to check:

• Press Win X and select Device Manager .
• Expand the Sound, video and game controllers section.
• Right-click each listed device (usually something with Realtek, Intel, or Conexant in the name) and select:
  • Update driver
  • Or, if the issue started recently, try Roll back driver if the option is available

If you're not sure which one to update, just update them all one by one. If none of them offer a rollback, you may need to download the latest driver manually from your motherboard or laptop manufacturer's website.

Reinstall audio drivers completely

Sometimes updating isn't enough — you may need to fully remove and reinstall the audio driver:

1. In Device Manager , right-click the audio device and choose Uninstall device .
2. Check the box that says “Delete the driver software for this device” if available.
3. Restart your computer — Windows will attempt to reinstall the driver automatically.

After rebooting, test your sound again. This method often resolves issues caused by corrupted or incompatible drivers.

Check for Windows updates and optional driver updates

Occasionally, Microsoft releases post-update patches that fix known bugs, including audio issues:

• Go to Settings > Update & Security > Windows Update .
• Click Check for updates .
• Also, click View optional updates , switch to the Driver updates tab, and see if there's a newer audio driver available.

Installing these updates could resolve compatibility issues introduced by a previous update.

That's basically it. Most audio issues after a Windows update come down to drivers or settings being changed unexpectedly. Start with the simplest checks and work your way through driver fixes. Usually, one of these steps will bring your sound back.
