Não é possível usar a saída de áudio frontal no Ubuntu 16.04

Question

Olá, bom dia, tenho um problema que não consigo resolver. Eu tenho procurado alguma solução possível, mas não esclareci muito. Meu problema é o seguinte, a torre de computador que eu tenho tem duas saídas de áudio na parte traseira e na frente na parte traseira funciona sem problemas, mas a frente eu não consegui fazer o trabalho. Então eu bato todas as informações que eu acho que podem servir e agradeço antecipadamente no caso de alguém poder me guiar para resolver o problema.

A saída do comando: lspci | grep Audio

00: 1b.0 Audio device: Intel Corporation 8 Series / C220 Series High Definition Audio Controller Chipset (rev 05)
01: 00.1 Audio device: Advanced Micro Devices, Inc. [AMD / ATI] Cape Verde / Pitcairn HDMI Audio [Radeon HD 7700/7800 Series]

Em Alsamixer eu posso ver as seguintes informações:

Card: HDA Intel PCH
Chip: IDT 92HD89E2

E no alsamixer também, nas informações do sistema:

Quanto aos diferentes controles que recebo no Alsamixer, há o seguinte:
