Ubuntu 16.10 sem som algum

Question

Áudio usado para trabalhar no meu sistema Ubuntu (não como deveria, mas funcionou). Algo aconteceu recentemente, eu não tenho ideia do que, mas agora eu perdi completamente o som.

Eu basicamente tentei tudo o que você pode encontrar olhando para os resultados do Google para este problema. Aqui estão alguns comandos e suas saídas:

Tente excluir em seu diretório pessoal os arquivos .asoundrc file e /etc/asound.conf (se você os tiver) e reinstale alsa-utils :

sudo apt-get remove --purge alsa-utils
sudo apt-get install alsa-utils
