голосовое управление Intel Edison - как настроить Alsa

Я хочу реализовать голосовое управление инвалидной коляской с помощью Intel Edison. В основном я скажу вперед, влево, вправо и остановлюсь на микрофоне, подключенном к плате Edison через звуковой адаптер .

Для первоначального прототипа я просто хочу отобразить вывод распознавания речи в CLI.

Я следую этому онлайн-уроку. Все хорошо, пока в разделе настройки звука.

Далее следуют CLI-команды, используемые в учебнике.

Что я должен сделать, чтобы это исправить?
