Позавчера поставил Ubuntu 12.04.4 на Toshiba Satellite L300. Поставил gnome-panel, установил несколько программ, обновился... и тут пропал звук. В настройках нет устройства, показывает только "Фиктивный выход", на колесико изменения громкости не реагирует. Вывод команд:
alsamixer
Не удаётся открыть микшер: Нет такого файла или каталога
pulseaudio
E: [pulseaudio] pid.c: Daemon already running.
E: [pulseaudio] main.c: pa_pid_file_create() не удалось.
