В alsamixer-е замутить через кнопку M все неиспользуемые входы/выходы, а не просто выкрутить ползунки в 0.
Все что можно замьютил. Причем входы не мьютятся (под ними даже нет квадрата с цифрами уровня или мм).В неиспользуемых убрал уровень до конца.
Если не поможет, то приведите вывод следующих команд:
cat /proc/asound/cards
arecord -L
amixer
lspci -v | grep Audio -A6

Не понял
Сигнал береться только с выбранного входа в pavucontrol и не обязательно мьютить остальные?
