次の方法で、順番に試していくと良い

1. 「設定」で、ミュートになっていないかを確認する
   
   
2. PipeWire を再起動
   
   

   $ ps aux | grep pipewire KanraKa+ 340222 0.0 0.0 261152 10888 ? S<sl 01:07 0:00 /usr/bin/pipewire $ kill -HUP 340222

    
3. Pipewire 用の PulseAudio をインストール
   
   

   $ sudo dnf install pipewire-pulseaudio –allowerasing

   
   PulseAudio を起動 ＆設定
   
   

   $ systemctl –user start pipewire-pulse.service  $ systemctl –user enable pipewire-pulse.service $ systemctl –user status pipewire-pulse.service ● pipewire-pulse.service – PipeWire PulseAudio            Loaded: loaded (/usr/lib/systemd/user/pipewire-pulse.service; enabled; vendor preset: disabled)            Active: active (running) since Thu 2022-01-13 11:03:57 JST; 3h 27min ago TriggeredBy: ● pipewire-pulse.socket      Main PID: 2843 (pipewire-pulse)            Tasks: 2 (limit: 154562)        Memory: 20.5M               CPU: 4min 51.350s         CGroup: /user.slice/user-1000.slice/user@1000.service/session.slice/pipewire-pulse.service                      └─2843 /usr/bin/pipewire-pulse $

   
   
   
4.  駄目なら再起動
