[Ubuntu 9.04]Внезапно пропадает звук.

Какая звуковуха? Какой метод вывода используешь - pulseaudio или alsa?

>Какой метод вывода используешь - pulseaudio или alsa?

Там же ясно сказано alsa...

По сабжу. Это же бубнта. Ничего внезапного.

что в логах? в dmesg? с пульсаудио глюки такие же?

> Там же ясно сказано alsa...
Так pulseaudio это вроде обёртка над ней или OSS, или я что-то не так понимаю?

И да, если выпиливал pulseaudio, то возможно что-то недопилил.

a alsa у тебя через jack идёт?

Звуковуха у меня встроенная на нвидийном чипсете, у брата - интеловская. Так что думаю проблема не тут. Действительно, стояло через pulseaudio, но при смене на ALSA не помогло (менял под в Volume Control).

Нашёл, но что делать с этим не знаю:

Похоже на багу Ubuntu или Pulseaudio. У себя в логах тоже нашёл многочисленные

Хотя не замечал проблемы (наверно потому, что не часто использую звук). У меня Intel HDA.

Куча программ проигнорируют такую замену. Вроде надо удалять pulseaudio, чтобы надежно никто через него не играл.

О! Удалил. Уже часа 2 не перезагружаю алсу, всё работает. Спасибо! Будем ждать дальше)
