Debian 系统似乎能识别扬声器，但不能识别联想笔记本电脑的耳机
Udi*_*pta 13 alsa laptop audio pulseaudio elementary-os
如果需要，我会很高兴/舒服地应用一些补丁或更改一些内核代码。我需要的只是方向，因为我不知道内核中的 Linux 声音架构（pulse-audio和alsamixer实现）。
我很确定一定有一些补丁，这个问题似乎非常普遍。
注意：这是描述：（可能会持续很长时间，但我想以任何方式完成它）。
我最初在我的笔记本电脑中安装了 Ubuntu 13.04。大约 2 个月未使用后，当我再次开始使用它时，我意识到我在任何地方都没有声音（扬声器、耳机等，甚至没有系统声音）。我升级到 Ubuntu 13.10，但问题依旧。[上次笔记本电脑处于挂起模式，我不知道是否与此有关]。我也怀疑这里有一些硬件故障。
此时，我有一个双引导系统（Ubuntu + Windows），我删除了它们并重新安装了 Elementary OS - Luna（基于 Ubuntu 12.04 LTS），但我又遇到了同样的问题。然后我做了以下配置，扬声器开始工作（见alsa-base.conf下面的片段），但不是耳机。当我插入耳机时，它没有改变 - 声音不断通过扬声器传出。
目前，我的系统中只有 Elementary OS - Freya beta（基于 Ubuntu 14.04）并且我遇到了同样的问题。扬声器工作但耳机不工作。插入耳机不会使扬声器静音，我也听不到耳机的声音。
# Adding these lines at the end of `alsa-base.conf`, speakers started
# working fine.
options snd-hda-intel model=laptop
options snd-hda-intel position_fix=1 enable=yes
我已经尝试了其他帖子中指定的很多选项，但似乎没有任何效果。例如：像尝试gnome-alsamixer耳机插孔感应选项，但没有提到“耳机”。
我无法提及我尝试过的所有内容，否则该帖子可能会很长且未被注意到，但如果需要，我会添加任何命令的输出。
我附上了一些基本内容的屏幕截图和配置，以开始了解我的系统中可能发生的情况。注意：连接或不连接耳机不会改变任何这些屏幕截图中的行为。
请为我提供正确的方向，因为这对我来说很重要，我不想仅仅因为这个愚蠢的错误而切换到 Windows，这似乎是所有基于 Debian 的系统的常见问题，所以我别无选择，如果这个错误仍然普遍存在。
