Внезапно пропал звук, speaker-test отдает переодичеcкие потрескивания.
Звук работает в tty [1-6], а в i3wm нет.

P.S. Гуглил перед этим, обычно у всех решения сводились к «оно само ожило», или «снес к чертям весь пакет KDE/GNOME, потом установил заново и все заработало». Пользователи рача обычно ждали обновления, но я не обновлялся перед пропажей звука.
