Добрый день.
Возможно кто-нибудь подскажет в чём проблема и как её решить.
[root@p4 kernel]# uname -r; cat /etc/altlinux-release
2.4.26-std-up-alt6
ALT Linux Sisyphus (20040826)
При просмотре передач периодически возникают звуковые помехи. Очень
похоже на белый шум. В такие моменты в логах ядра
(/var/log/kernel/info) появляется следующее:

Звуковая карта встроенная. Вывод lspci -n и lspci -v прилагается.
Спасибо.

Гм.. Сам себе и отвечаю. :-) Ужыс! Лишь бы в привычку не вошло. ;-)
Методом втыка определил, что достаточно в xawtv выбрать audio mode
"mono" вместо "stereo" и шумы пропадают.

Наверное, качество сигнала периодически колеблется в пограничном
интервале. Это мне представляется наиболее логичным объяснением.

Но при этом под оффтопиком такого не наблюдается. Возможно проблема в
драйверах.
