pavelchavyr
Эта карта поддерживает аппаратно разные частоты дискредитации. Браузер работает через пульсу, которая принудительно пересемплирует все потоки в один. Но если какое-то приложение при этом пытается обратиться напрямую к алсе, то может переключить частоту и тогда звуки от браузера становятся искаженными.
пакет pulseaudio-alsa установлен?
