Bluetoothは奇妙に動作します。再起動後、ヘッドフォンを簡単に接続できますが、blueman-managerサウンド設定には表示されず、音がpavucontrolスピーカーから出ます。ただし、sudo systemctl restart bluetoothヘッドセットを介してBluetoothを再起動すると、正しいプロファイル（A2PまたはHFP）に接続して設定に表示され、次回再起動するまで正常に動作します。私はインターネット全体を検索するのに数時間を費やし、Bluetoothにのみ関連するすべてのものを消去して再インストールし、pulseaudioを削除または終了し続け、~/.config/pulseモジュールのロードとアンロードなど、限られたLinuxの知識で理解できるすべての可能なソリューションを試しました。 。var/lib/bluetoothしかし、成功しませんでした。以下では、この動作を「研究」したい「実験」の結果を見つけることができます。明らかに私は多くのバグを経験しましservice bluetooth statusたが、奇妙なことに、そのバグにもかかわらず、電話はまだうまくいきました。
私のシステムにどのような問題があるかを知っている人はいますか？

1.ヘッドホン（hp）が接続されていません：

Bluetoothの問題を削除して解決しましたbluez-alsa-utils。どういうわけかこのパッケージはpulseaudioを妨げます。これで PipeWire エラーが発生します。
「PipeWireに接続できません：ノードファクトリが見つかりません」
しかし、これが音に影響を与えない限り（そうでないようです）私は大丈夫です。
