Ubuntu 14.04 El audio digital deja de funcionar

0

Tengo un Ubuntu 14.04 HTPC desde hace bastante tiempo. Está conectado mediante un enlace a un logitech z5500. El sonido estaba funcionando, pero de repente se detuvo ...

He seguido casi todas las guías y procedimientos para arreglar mi sonido, pero no parece ayudar.

Alguna información:

Le animaría a mover esta pregunta al sitio de Ubuntu Exhange (AskUbuntu, no recuerdo el nombre). Esta no es una pregunta mala o fuera de tema, pero la ayuda allí con tales preguntas específicas probablemente funcionaría bien.

Esto le sucedió a mi portátil Ubuntu antes; ¿Has intentado reiniciarlo?
