Question

Bluetoothでヘッドホンを認識しない

Answer 1

Hi, I am an Independent Advisor.

Let me help you with this issue.

I understand you are having problems with your Bluetooth.

May I know the make and model of your device?

Have you tried restarting your machine?

When was the last time it worked fine?

Please run the Bluetooth troubleshooter to identify the problem.

Select Start > Settings > System > Troubleshoot > Other troubleshooters. Next to Bluetooth, select Run and follow the instructions.

If you recently upgraded to Windows 11 or installed Windows 11 updates, the current driver may have been designed for an earlier version of Windows. To automatically check for driver updates:

Select Search on the taskbar, type device manager, and then select Device Manager from the list of results.

In Device Manager, select Bluetooth, and then select the Bluetooth adapter name, which may include the word “radio.”

Press and hold (or right-click) the Bluetooth adapter, and then select Update driver > Search automatically for updated driver software. Follow the steps, then select Close.

After installing the updated driver, select Start > Power > Restart if you're prompted to restart, and then check whether that fixes the connection issue.

If Windows can’t find a new Bluetooth driver, visit the PC manufacturer’s website and download the latest Bluetooth driver from there.

他のデバイス（スマートフォンでも可）にヘッドホンを Bluetooth 接続して、正しく認識され機能するか確認しましょう。

他のデバイスでも認識されなければヘッドホンの故障です。

後は、PC のBIOS を最新に更新して、他の機器に接続して動作確認ですね。
