Добрый вечер.
Отправил это письмо в hardware@, но возможно не по адресу, поэтому решил
продублировать его сюда.
Возможно кто-нибудь подскажет в чём проблема и как её решить.

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.
p.s. Проблем с FM-тюнером не наблюдается.
