Прежде чем я запущу, я использую 4.11.2 ядер низкой задержки, в приоритете в реальном времени включают /etc/security/limits.conf
. Группа пользователей в реальном времени и т.д. была настроена. Jack, кажется, хорошо работает с ALSA.
Я использую ‘Масштабирование H5’ магнитофон как аудиоинтерфейс USB с Ubuntu 14.04. Масштабирование H5 имеет 2 различных режима аудиоинтерфейса: (1) 'Стерео' - который позволяет Вам записывать один стереоканал и (2) 'Многодорожечный', который позволяет Вам записывать 4 моноканала сразу.
ВЫПУСТИТЕ ТОТ
Если я выбираю 'Стерео', Масштабирование, H5 распознан как версия-предшественник (H-4 Масштабирования) как входная опция и как выходная опция ALSA.
Однако звуковой сигнал от Масштабирования, которое вводит H5, не идет никуда. Сигнал ни не принят моим аудио программным обеспечением, и при этом это не hearable, когда я соединяю его в Jack непосредственно к системному выводу (моя внутренняя карта Intel).
Вот вывод от Jack Messages:

ПРОБЛЕМА ДВА
Если я выбираю 'Многодорожечный' на Масштабировании H5, Масштабирование, H5 распознан только как устройство вывода ALSA. Однако это не распознано как устройство ввода данных, хотя 4 моно канала ввода обеспечиваются Масштабированием H5. Кроме того, когда Многодорожечный выбран, устройство Масштабирования распознано как 'H5' моей системой. Хотя ALSA не распознает Масштабирование устройство записи H5 как устройство ввода данных (когда Многодорожечный выбран на Масштабировании H5), Jack Audio распознает его и показывает 4 моно исходных данные. Однако проблема состоит в том, что стандартный аудиовыход, который является простой внутренней картой Intel hw:1
не показан и поэтому не можно выбрать в Jack. Выходные опции 'playback_1' и 'playback_2' являются выводами Масштабирования, H5 и звук выходят из Масштабирования H5 вместо динамиков компьютера.
Вот ‘вывод’ сообщения Jack после начинающего Jack

Sun May 21 00:35:40 2017: Released audio card Audio1
Я проверил, какие аудио модули в настоящее время активируются в моей системе cat /proc/asound/modules
и это показывает, что устройство Intel активируется, а также Масштабирование H5:
0 snd_hda_intel
1 snd_hda_intel
2 snd_usb_audio
Кроме того, вот aplay -l
вывод:
