Динамик не работает после использования HDMI

Итак, я попытался использовать свой ноутбук (Asus GU501) для просмотра фильма на телевизоре через кабель HDMI, но в Ubuntu 16.04 произошла ошибка (что связано с настройкой графики; диалоговое окно с черным экраном) во время запуска.

Я перезапустил систему (нажав кнопку питания на 10 секунд). Когда я включил его снова, динамики больше не работали; даже в Windows 10 или Arch. Post Logo Animation (логотип ROG) при запуске ноутбука не воспроизводит звук, как обычно.

Alsa продолжает показывать внутренние динамики в качестве опции вывода, я могу использовать выход P2, а lscpci -v показывает устройство.

Есть ли шанс, что Ubuntu выключит динамики? Или, может быть, произошло что-то связанное с secureboot?

Пожалуйста, помогите:<
