ubuntu 17.10 sem som

Question

Acabei de atualizar meu sistema de 17.04 para 17.10. Após a atualização, não tenho som no meu sistema a partir de qualquer saída (saída analógica ou HDMI via GPU).

Na guia de som sob as configurações, nenhum dispositivo é listado.

Eu também instalei o áudio de pulso, mas ele não inicia ...

Me deparei com outros posts na internet onde as pessoas não têm som no ubuntu 17.10 mas ninguém postou uma solução ... Alguém sabe como consertar isso? Obrigado antecipadamente

Você precisa atualizar o kernel do Linux e instalar o driver atual do Mesa, eu tive o mesmo problema aqui com o Radeon RX560 no Ubuntu 17.10, funciona! Mesa: link Núcleo: link
