O dispositivo no gerenciador é exibido como: Saída digital (S / PDIF) - Áudio incorporado Perfil: Saída Estéreo Digital (IEC958)
Notei que nas instalações anteriores do Ubuntu (12, 14 e 16) eu notei que o dispositivo de som seria um dispositivo analógico. Notei que uma vez que eu atualizei o sistema, se foi para o digital como mostrado acima, o som morre e não consigo me recuperar.
Instalei o PulseAudio, o que não ajudou.
Alguém tem alguma sugestão?
