USB-микрофон камеры в реальном времени не записывает звук

Я пытался записывать видео + аудио, используя сыр. Видео было записано, аудио - нет. Я пытался исправить:

1. Запуск alsamixer -c1 и увеличение громкости до 100%
2. Открытие pavucontrol и установка угла справа на 0, угла слева на 100% Все не сработало: если я записываю звук, то я слышу только шум на выходе моих динамиков.

Вот результат pacmd list-cards :
