Clojure & Overtone: Jackd не запускается

Question

Я пытаюсь использовать Overtone, но когда я его запускаю, я получаю сообщение об ошибке jackd.

Это почти новая установка Ubuntu 14.04, где я установил Leiningen и попытался установить, что предлагается здесь: https://github.com/overtone/overtone/wiki/Installing-and-starting-jack

Команда jackd они предлагают работать не работает, либо и дает ошибки слишком ,

Answer 1

Это связано с тем, что конфигурации вашего гнезда не установлены правильно с вашей звуковой картой. Попробуйте загрузить QJackCtl (графический интерфейс для jackd) и запустить разъем перед обедом Overtone. Если вы успешно запускаете гнездо с помощью QJackCtl, то обертон должен начинаться должным образом. В Ubuntu вы сможете найти его с помощью apt-get install qjack *

Обратите внимание, что вы можете выбрать воспроизведение только в том случае, если вы не знаете, как настроить линейный вход (например, микрофон).
