在 ubuntu 16.04 中无法使用前置音频输出

你好，早上好，我有一个无法解决的问题。我一直在寻找一些可能的解决方案，但并没有弄清楚。我的问题如下，我的电脑机箱后面有两个音频输出，后面的前面工作正常，但前面我无法让它工作。然后我找到了我认为有用的所有信息，如果有人能指导我解决问题，我提前谢谢您。

命令的输出：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]

在 Alsamixer 中我可以看到以下信息：

Card: HDA Intel PCH
Chip: IDT 92HD89E2

在 alsamixer 中也是如此，在系统信息中：

/ Proc / asound / cards
0 [PCH]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf7f10000 irq 31

00-02: 92HD89E2 Alt Analog: 92HD89E2 Alt Analog: capture 1

至于我在 Alsamixer 中获得的不同控制，有以下几点：

<Master> PCM Front Surround Center LFE Side Line Line Boo Line Boo Mic Boos Mic Boos S / PDIF S / PDIF D Beep Capture Capture Digital Input So Input So Loopback

命令输出：aplay -l
