お使いのデバイスがシステム上で再ペアリングされます。ドライバーのバグや接続エラーが原因で問題が発生した場合でも、デバイスを介してオーディオを再生できるようになりました。

ヒント: オーディオ デバイスのマイクやその他のサービスを無効にして、品質や音量を改善したり、オーディオを完全に機能させたりする必要がある場合があります。このガイドを読み終わったら、上部のセクションを参照して追加サービスを無効にすることをお勧めします。

修正 11: ヘッドセットのマイクを無効にする

それでも Bluetooth デバイスでオーディオを再生できない場合は、デバイスのヘッドセット コンポーネントを無効にすることをお勧めします。これは、オンボード マイクを搭載したデバイスに適用される修正です。お使いのデバイスにマイクがない場合は、この修正をスキップして、以下の修正に進んでください。

Windows 11 は、これらのコンポーネントが同じデバイス用であっても、マイクとオーディオ出力を別々に処理します。これにより、マイクが常にアクティブになり、デバイスでオーディオを再生できないという既知のバグが発生する可能性があります。マイクを無効にすると、システムでこの問題を解決できる場合があります。以下の手順に従って、プロセスを進めてください。

Fix 14: Disable the Bluetooth LE enumerator
