Звуковой интерфейс Gnome не имеет разрешения на доступ к управлению звуком

Я ищу разрешение отключенного звукового интерфейса в установке Ubuntu 19.10. Я думаю, что это связано с аудиопакетом «remixer», который я установил, но больше не могу найти, который зацепился между Pulse-audio и системным интерфейсом и теперь блокирует доступ к API-интерфейсу pulse-audio.

Пожалуйста, дайте мне знать, что вам нужно, чтобы помочь мне решить проблему.

На рисунке показан звуковой интерфейс, который не имеет доступа к серверу Pulse-Audio.

user@system:~$ echo autospawn = no >> ~/.config/pulse/client.conf  #use ~/.pulse/client.conf on Ubuntu <= 12.10
user@system:~$ killall pulseaudio
user@system:~$ LANG=C pulseaudio -vvvv --log-time=1 > ~/pulseverbose.log 2>&1
user@system:~$ cat pulseverbose.log
