Не может запустить QjackCtl

Я использую Ubuntu Studio 16.04 LTS.

Когда я использую аудио приложение WineHQ с pulseaudio, я не могу запустить QjackCtl.

То приложение дает мне следующие сообщения об ошибках:

"Сервер аудио Jack не мог быть запущен.Прошу прощения. Посмотрите окно сообщений".

И... окно сообщений говорит мне:

Я - не программист, таким образом...

Что случилось здесь???
