私は Arozzi Sfera 卓上マイクを持っています。背面にヘッドフォン ジャックがあり、おそらくモニター用だと思います。
マイクを接続すると、設定ビューの「サウンド」タブに、Bluetooth ヘッドフォン、ディスプレイへの HDMI 接続、マイクなど、さまざまなオーディオ出力デバイスが表示されます。出力デバイスを選択して「テスト」機能を使用すると、オーディオはマイクのヘッドフォン ジャックに送られます。
実行しようとしましたpulseaudio -kが、systemctl --user restart pulseaudio.service問題が発生しても効果はありませんでした。

alsa-card モジュールを番号でアンロードすると (pactl unload-module 8この場合は)、入力としてのマイクも無効になります。
pactl infoデフォルトのシンクは であると表示されますbluez_sink.2C_4D_79_40_C5_3B.a2dp_sink。設定からオーディオ出力を変更すると、これが変わります。
おそらく関連する問題として、マイクを切断して再接続すると、オーディオ設定でマイクが「デフォルト」出力として表示されることがあります。
もう 1 つの観察: アプリケーションの設定 (たとえば Discord デスクトップ アプリ) でオーディオ シンクを明示的に設定すると、それが機能します。この動作を示すのは、デフォルトのシンクと gnome のみであるようです。
今年 3 月末頃から、この動作が頻繁に起こるようになったようです。30 日には正常に動作していたことがわかっています。唯一の解決策は、マイクを抜くことです。
これを修正する方法を知りたいです。それができない場合は、適切な相手にバグレポートを送れる程度にこれを診断する方法を知りたいです。
答え1
解決策を見つけたと思います。 を使用してpavucontrol、マイクのオーディオ プロファイルを見つけましたが、それに設定されているプロファイルは「デジタル ステレオ出力 + モノラル入力」であり、pulseaudio を混乱させていました。これが出力プロファイルだと思いますiec958-stereo+input。
mono-fallbackこれを「モノ入力」だけに変更すると、問題は解決したと思います。
