Не удается запустить QjackCtl

Я использую Ubuntu Studio 16.04 LTS.

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

Это приложение дает мне следующие сообщения об ошибках :

«Не удалось запустить звуковой сервер Джека. Извините, см. окно сообщений.»

И ... окно сообщений сообщает мне:
