Внутренний микрофон отключен на HP Zbook G6 на Kubuntu 19.10

Я пытаюсь заставить работать мой внутренний микрофон. В pavucontrol я не видел никаких устройств ввода. [ 1 ] Я переключил «Встроенный звук» на «Аналоговый стерео дуплекс». После этого есть устройство ввода, но с указанием оно отключено. [ 2 ] Я также пытался отключить один из каналов, но безуспешно. Захват в alsamixer пронумерован. [ 3 ]. Я мог подключить беспроводную гарнитуру, как думал микрофон.

Вот некоторые результаты:
