Сам микрофон подключается и определяется, но звука с него нет. Проверял alsamixer, каналы микрофона не замучены. Через pavucontrol смотрел, ползунок звука с микрофона на нуле. Вывод dmesg:

Как видим микрофон определяется. Еще выводы разных команд, которые могут пригодиться:

Пробовал подключать микрофон к ноутбуку, телефону - микрофон работал. На ноутбуке стоит так же арч, как и на компе
