Запись от Строки в разъеме

Мне подключили звуковую карту usb к моей машине, и я пытаюсь записать от "строки в", но jackd, кажется, рассматривает его как устройство воспроизведения даже при том, что у меня есть он набор как устройство захвата изображения в alsa (см. ниже), любой знает, как я могу получить разъем к этой "строке в" как получение. Как Вы видите ниже разъема, видит только 2 устройства захвата изображения, которые приравниваются к исходным данным на 2 микрометра на карте. Я ожидал видеть, что 3 получения включают "строку в"
