[ЗАКРЫТО]: ОС не видит проводные наушники.
Проблема в выводе аудио через проводные наушники. Весь Инет перерыл за пару недель, всё перепробовал, не получается.
Динамики работают, а наушники нет (в Windows этот же вход и эти же наушники работают).
Показывает одну звуковую карту, перечисляет все HDMI, микрофон, а о headphones ни слова.
Подскажите, пожалуйста, как можно их включить?

В каком выводе нет headphone?Vikinlin:Показывает одну звуковую карту, перечисляет все HDMI, микрофон, а о headphones ни слова.
А в этом выводе имеется Headphone?:
amixer -c 0 | grep -E 'Speaker|Headphone'

и …Vikinlin: alsa.card = "0"

Разбирайся со своим аудиокартами … начни с Intel, с ней проблем быть не должно. Кстати, активировать ее можешь с помощью того же amixer (хотя, как удобнее так и делай).
PS - в части Intel, обрати внимание на

Смотри выводы команд
aplay -l
cat /proc/asound/modules
pacmd list-sinks (без подключенных наушников и с подключенными наушниками)
можно посмотреть и логи: journalctl -b | grep -i error
желательно посмотреть и выводы lspci -vs 00:xx.y (где 00:xx.y = lspci | grep Audio | awk '{print $1}')
Ошибки не исчезают с опытом - они просто умнеют
aplay -l; cat /proc/asound/modules; lspci -vs 00:xx.y - ничего подозрительного, вроде.vasek:Для получения большей информации и ее анализа
pacmd list-sinks в двух вариантах - информация идентична. О наушниках нигде ни слова.
