今朝からヘッドフォンを接続すると、すごい「心拍数」の音が聞こえました。それらを通して音は再生されません。ノートパソコンのスピーカーから音がよく聞こえます。
私はPop!_OSバージョン18.10を実行しています。
私のラップトップは次のとおりです
ASUS ROG Strix ヒーローエディション
Intel Core i7-8750H CPU @ 2.20GHz
Nvidia GeForce GTX 1050 Ti
16GB RAM
「ループバック」をオフにするためにAlsaMixerを介して修正しようとしましたが、私のバージョンのAlsaMixer（バージョン1.1.6）には表示されません。したがって、無効にすることはできません。
私も走ろうとしましたが、pasuspender -- speaker-test -D hw:0 -c 2 -t wav何も聞こえませんでした。ちょうどハートビート。

他の細部:
- FireFoxをブラウザとして使用しています
- Windows 10とPop!_OSをデュアルブートします。
ヘッドセットはWindowsでうまく動作します。
