Por favor, note que tentei todas as soluções nos dois links abaixo:
Som "Dummy Output" no Ubuntu 14.04
Nenhuma placa de som detectada em Sound Settings, embora trabalhos de som
pulseaudio -k && sudo alsa force-reload
não resolve o problema
pacmd list-cards
mostra 0 card(s) available.
Quando o som estava funcionando bem no meu 18.04 antes, tentei modificar /etc/modprobe.d/alsa-base.conf
para resolver um problema diferente após responder . Mas depois que meu som parou de funcionar, removi as linhas adicionadas que colocavam os drivers na lista negra. Isso poderia ter causado o meu problema?
Por favor, ajude-me, não posso trabalhar sem som no meu PC por muito tempo
Atualizar :
Como tenho o Dual Boot no PC, inicializei no Windows em que também o som não estava funcionando, o solucionador de problemas do Windows não identificou o problema, então entrei no Gerenciador de Dispositivos e reinstalei o Realtek HD Audio Controller , Ele não resolveu o meu problema, o som ainda não estava tocando, mas uma coisa notável que ocorreu foi quando eu voltei para o Ubuntu 18.04, ele detectou um built-in de áudio
e agora pacmd list-cards
