Народ, кто будет хотеть серьезно юзать subj, учтите несколько неприятностей.
1. Та кнопка, что в винде управляет громкостью (слева вверху) в Линухе не поддерживается.
2. Регулировать громкость из OPIE не получится.

Прилагаемый патч это лечит.
(Оставляю свои координаты, дабы было ясно, что я не хакер, который хочет всем нагадить).
