Добрый день.

Возможно кто-нибудь подскажет в чём проблема и как её решить. 

[root на 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.
