Tudo estava bem com o Ubuntu 14.04. Eu meio que estraguei tudo quando instalei a área de trabalho do KDE Plasma em cima dela. Então, apenas formatado tudo e instalado 16.04. Agora, as portas de áudio traseiras funcionam bem, mas a porta de áudio frontal não funciona. Tentei acertar os fones e aumentar o volume do Alsamixer, não funcionou. Preciso de drivers extras? Os fones de ouvido emitem algum ruído estático sempre que faço qualquer coisa no meu PC, digamos que um código esteja em execução.

Estou em um PC de mesa executando o processador Intel (R) Core (TM) i7 com 950 @ 3,07 GHz * 8 com 16 GB de RAM. NVIDIA GT218. Deve ser óbvio, mas este é o meu PC do escritório e eu preciso dessa porta de áudio frontal para ouvir música! Conectar-se às portas traseiras tornará as coisas muito apertadas.
