Eu tenho um notebook Asus N550JA, e ele tem um subwoofer externo, que não funciona desde o Ubuntu 14.04.4, por estranho que pareça funciona com o Ubuntu 14.04.3, mas depois de atualizações ele não funciona, parece ser algo com configurações alsa.
Eu quero fazer funcionar agora no Ubuntu 16.10. Alguém pode me ajudar com esse problema?
