Титла: Въпросче за System timer
Публикувано от: completer в Jan 06, 2009, 20:17
Инсталирах си Rosegarden чрез synaptic и като я пускам ми излиза всеки път една и съща грешка: "System timer resolution too low" Реших да вида в какво по точно е грешката и като пусна през терминала: AlsaDriver::setCurrentTimer((auto))
System timer is only 250Hz, sending a warning
Current timer set to "system timer"
WARNING: using system timer with only 250Hz resolution!

Виж това: http://www.linuxforums.org/forum/linux-kernel/109145-system-timer-resolution-audio-apps.html
Доколкото знам тази резолюция е за сървъри или десктоп системи, при който не се изисква бърза реакция. Преди на Gentoo, когато си компилирах ядрото знам че слагах 1000, което беше препоръчително за десктоп система.

Здравей!
При положение,че - JACK server not running ...
Най вероятно се касае за липсата на Jack Control ...

Тук има доста казано по въпроса!
Поздрав!

Ясно ще трябва да се прекомпира ядрото.А пък е и страхотна идея да си пускам едно live cd с 64studio когато искам да правя някакава музика.Благодаря и на двама Ви!
