USB ЦАП производит шумовой шум

Хорошо, вот история. У меня есть лаборатория JDS. USB-ЦАП C5D около года, а вчера я хотел попробовать Ubuntu 14.04. Итак, я установил Ubuntu, сделал некоторые обновления и подключил ЦАП (использовались команды sudo alsa reload и killall pulseaudio).

После того, как я вошел в меню « Настройки звука » и выбрал аналоговый выход для C5D, я попробовал проверить звук. « Левый передний » и « Правый передний » звук воспроизводится как « Hrrr Hrrrr "и" Hrrrr Hrrrr ". Я даже пытался воспроизвести музыку и видео - тот же результат.

Может быть, проблема с ЦАП? Итак, я загрузил Windows, а затем Kali Linux, он отлично работал в обоих.

После возвращения в Ubuntu я пытался проверить, правильно ли система распознает ЦАП, поэтому для некоторой команды это выводится:

Таким образом, ЦАП распознан правильно.

Есть предложения, друзья? И извините за мой плохой английский;)
