Здравствуйте
Kubuntu 12.10
Иногда при загрузке системы или при выходе из ждущего режима тормозит звуковая подсистема.
Подозреваю, что Pulseaudio неправильно определяет мою веб-камеру Logitech и пытается подключить её как-то не так. Из-за этого нет звука, phonon (звуковой менеджер) загружается с двухминутной задержкой. При попытке получить настройки пульса (pactl list) выводится сообщение о превышении времени ожидания ответа. В сислог сыпется следующее:

Если отключить веб-камеру из порта, всё может начать работать. Сообщения в сислог перестают сыпаться, пульсаудио отвечает на запросы (однако некоторые глюки в системе всё-таки остаются - например, не могу выделить ответ из терминала на команду pactl list - консоль намертво зависает при попытке выделения. Не регулируется громкость)
Если вставить вебку в другой порт, всё может начать работать, но не всегда. Иногда снова начинают сыпаться те же сообщения:

Кто виноват, и что делать?
Встречал сообщения, что пульс может зацикливаться с одного устройства на другое. Из-за этого могут быть такие ошибки. Но как это определить, если он в момент ошибок не отвечает?
