Отвалился звук.

Ничто как обычно не предвещало беды. Сегодня после загрузки перестал работать звук. В микшере все на максимум. В амароке треки просто переключаются друг за другом, пока плейлист не заканчивается, в настройках если попробовать протестировать систему, кнопка просто зависает, звука нет.
Ничего не ставилось, не конфигурировалось, не менялось. Из обновлений за вчерашний день только cups.

Если выполнить sudo alsa force-reload появляется
"Одно или несколько внутренних звуковых устройств были удалены.
Удалить эти устройства из списка используемых в KDE?"
где перечисляются аудиовход и аудиовыходы.

При загруке с live-cd звук работает. Но переустанавливать всё систему после недели работы это нонсенс. Помогите, пожалуйста.
