若聲音在驅(qū)動更新後失效，通常因驅(qū)動衝突或兼容性問題所致，可按以下步驟排查解決：1.嘗試回滾或卸載驅(qū)動；2.檢查設(shè)備是否啟用並被正確識別；3.運行音頻疑難解答工具；4.重新安裝兼容的驅(qū)動版本；5.核對音頻輸出格式設(shè)置。依次操作多可恢復(fù)音頻功能。

If you're wondering why your sound stopped working after a driver update, you're not alone. It's actually a pretty common issue — sometimes Windows updates or manual driver upgrades can mess with audio settings, especially if the new driver isn't fully compatible or something goes wrong during installation.

1. Check for Driver Conflicts or Rollback Options

After a driver update, one of the most frequent causes of audio issues is a conflict between the newly installed driver and your system configuration.

• Try rolling back the driver to the previous version:
  • Right-click on the Start menu and select Device Manager
  • Expand the Sound, video and game controllers section
  • Right-click your audio device > Properties > Driver tab > click Roll Back Driver (if available)

If the "Roll Back" option is grayed out, it might mean that no previous version is saved. In that case, try uninstalling the current driver and letting Windows reinstall an older or more stable version automatically.

2. Verify Audio Device Is Enabled and Recognized

Sometimes, after an update, your system might disable the audio device by mistake or fail to detect it properly.

• Go to Device Manager , as mentioned above
• If you see any yellow exclamation marks next to your audio devices, that's a red flag
• Right-click the device and choose Enable device if it's disabled
• If the device isn't showing up at all, you may need to manually scan for hardware changes from the Action menu in Device Manager

Also, check your physical connections — yes, even though it seems obvious, sometimes people overlook whether speakers or headphones are properly plugged in or powered on.

3. Run the Built-in Audio Troubleshooter

Windows has a handy tool called the Audio Troubleshooter that can detect and fix common audio problems automatically.

• Go to Settings > System > Sound
• Scroll down and click Troubleshoot under the "Related settings" section
• Follow the prompts and let the tool scan for issues

This doesn't always solve everything, but it often catches small glitches caused by recent system or driver changes.

4. Reinstall or Update to a Compatible Driver Version

If none of the above work, it might be time to go straight to the source: your motherboard or audio hardware manufacturer's website.

• Identify your exact audio chipset (you can use tools like Speccy or check under Device Manager)
• Go to the official site (Realtek, Intel, AMD, etc.) and download the latest compatible driver
• Make sure you pick the correct version for your OS (32-bit vs 64-bit matters here)

Some users find that installing the latest beta driver fixes bugs that the standard Windows update missed.

Bonus Tip: Check the Audio Output Format

Another thing that often gets overlooked — especially after an update — is the default audio format. Sometimes the sample rate or bit depth changes, and your system might not play sound because it's set to something your speakers don't support.

• Right-click the speaker icon in the taskbar > Sounds or Sound Settings
• Go to the Playback tab > double-click your default device
• Under the Advanced tab, try switching the default format to something like “44100 Hz” or whatever matches your usual setup

基本上就這些。
Most of the time, one of these steps will get your sound back up and running. The trickiest part is usually figuring out which step applies to your specific situation — but once you start checking each possibility methodically, the problem tends to reveal itself.
