Потребовалось мне тут заняться оцифровкой аудио, установил знакомую программу Audacity и начал работу...
В процессе иногда появляются косяки в звуке - при проигрывании начинается хрип, программа зависает, приходится насильно закрывать. При записи пару раз просто останавливался с таким же "хриплым" косяком. т.е. начинает хрипеть и через 3-4 сек. встает колом.
Один раз так зависло, что пришлось комп перегружать, так как во всех аудиопрограммах хрипело воспроизведение.
Железо: мать intel dg451d, звук встроенный. (ICH10R + IDT 92HD73E codec)
в софте все стоит по умолчанию - ALSA и Pulse (в самом Audacity - default в настройках).
Есть возможность поставить звуковуху SB0100, но будет ли лучше?

Тут можно только попробовать. По моему опыту отдельная звуковуха работает сильно качественнее.

Отключил встроенную звуковуху, поставил SB. Пару часов поработал в audacity - все нормально, зависонов нет.

Случайно не так ли настроено как на картинках? Эффекты? Разрядность и частота дискретизации?
Лучше чтоб было 16-бит/44100Гц. Не все встроенные звуковые адаптеры способны работать от 24-бит/48000Гц и выше.
Например, у меня так с консоли

и вылет.
Независимо какие настройки в параметрах все равно вылет.

цифровал на 44100 \ 16, так что тут проблемы нет. при проигрывании музыки тоже зависаний не было. а вот в редакторе косяки полезли..
