Eu tenho antergos e gnome como DE inicializado com o windows 10.
Tudo estava ok até que eu liguei o laptop e reproduzi um filme, não havia som (também não há som quando os fones de ouvido estão conectados)
Há som no Windows, então não é um problema de hardware.
Aqui estão alguns detalhes do sistema:

O sistema está totalmente atualizado e eu tentei reinstalar o botão pulsuceatrol pulseaudio-alsa pulseaudio-bluetooth alsa-firmware alsa-lib alsa-utils
Nada funcionou :( Eu gosto do Arch Linux, mas às vezes fica irritante.
