Eu comprei o Lenovo ideapad 500S e instalei o Debian 8. É uma nova instalação, e nenhum outro SO está neste computador.
Estou tendo dificuldade em permitir que o áudio e os dias de googling caçam qualquer dica que não tenha resultado algum.
Vou escrever algumas saídas nos comandos abaixo. Qualquer ajuda apreciada.
