首先檢查物理連接和硬件，確保有線耳機插入正確設備並測試其在其他設備上的工作情況，藍牙耳機則需確認電量、配對模式並重新配對；2. 將耳機設置為默認音頻設備，通過聲音設置中的播放選項卡啟用並設為默認；3. 更新或重裝音頻驅動程序，可通過設備管理器手動更新或使用Windows Update安裝可選驅動更新；4. 運行系統(tǒng)自帶的音頻疑難解答工具，自動檢測並修復常見問題；5. 重啟Windows音頻相關服務，並禁用音頻增強功能以排除乾擾；6. 檢查BIOS/UEFI設置中是否啟用了板載音頻，同時確認筆記本無物理靜音開關或功能鍵禁用音頻。按照以上步驟逐一排查，大多數(shù)Windows 11耳機無法檢測的問題均可解決。

If your headphones aren't being detected in Windows 11, it can be frustrating—especially if you rely on them for work, calls, or entertainment. The good news is that this issue is often fixable with a few straightforward troubleshooting steps. Here's how to get your headphones working again.

1. Check the Physical Connection and Hardware

Before diving into software fixes, rule out basic hardware issues:

• For wired headphones:

  
  • Plug them into another device (like a phone or tablet) to confirm they work.
  • Try a different USB or audio jack port on your PC.
  • If using a 3.5mm jack, make sure it's fully inserted. Look for a faint "pop" sound when plugging in—this indicates the port detected a device.
  • Avoid using extension cables or hubs; connect directly when possible.

• For Bluetooth headphones:

  • Make sure they're charged and in pairing mode.
  • Turn Bluetooth off and on again on your PC.
  • Remove and re-pair the device in Settings > Bluetooth & devices .

2. Set Headphones as the Default Audio Device

Sometimes Windows detects the headphones but doesn't use them by default.

1. Right-click the speaker icon in the taskbar and select Sounds or Open Sound settings .
2. Go to Sound Control Panel (on the right).
3. In the Playback tab, look for your headphones. If they appear but are grayed out, right-click and choose Enable .
4. Right-click your headphones and select Set as Default Device .
5. Click Apply and test the audio.

? Tip: If you don't see your headphones listed, click Show disabled devices and Show disconnected devices in the Playback tab.

3. Update or Reinstall Audio Drivers

Outdated or corrupted audio drivers are a common cause.

Option A: Use Device Manager

1. Press Win X and select Device Manager .
2. Expand Audio inputs and outputs and Sound, video and game controllers .
3. Right-click your audio device (eg, Realtek, Intel SST, or your headset name) and choose Update driver > Search automatically .
4. If that doesn't help, choose Uninstall device , then restart your PC. Windows will reinstall the driver automatically.

Option B: Use Windows Update (Recommended in Win 11)

• Go to Settings > Windows Update > Advanced options > Optional updates .
• Check under Driver updates —if audio drivers are listed, install them.

4. Run the Audio Troubleshooter

Windows 11 has a built-in tool that can detect and fix common audio problems.

1. Go to Settings > System > Sound .
2. Scroll down and click Troubleshoot common sound problems .
3. Follow the prompts and let Windows scan for issues.

It may detect problems like:

• No audio output device found
• Driver issues
• Incorrect default device

Apply the suggested fixes and test your headphones afterward.

5. Check Audio Services and Enhancements

Sometimes background services or audio enhancements interfere.

• Restart Audio Services:

  1. Press Win R , type services.msc , and press Enter.
  2. Find Windows Audio , right-click and choose Restart .
  3. Do the same for Windows Audio Endpoint Builder .

• Disable Audio Enhancements:

  1. Right-click the speaker icon > Sounds > Playback tab .
  2. Double-click your headphones.
  3. Go to the Enhancements tab and check Disable all enhancements .
  4. Click Apply .

6. Check BIOS/UEFI and Hardware Settings

Some laptops disable audio jacks when certain settings are active (eg, combo jack for mic headphones).

• Restart and enter BIOS/UEFI (usually by pressing F2, F10, or Del during boot).
• Look for audio or port settings—ensure onboard audio is Enabled .
• Save and exit.

Also, some laptops have a physical mute switch or function key (like Fn F4 ) that disables audio—check your laptop's manual.

Final Thoughts

Most headphone detection issues in Windows 11 come down to driver problems, incorrect defaults, or simple connection glitches. Start with the basics—check the plug, test on another device, and run the audio troubleshooter—then move to drivers and settings if needed.

It's not always obvious, but even a recent Windows update can temporarily break audio detection. Restarting or rolling back a driver update might help in those cases.

Basically, try these steps in order, and your headphones should be back up and running.
