蓝牙耳机暂停/播放按钮不起作用

我一直在尝试在运行 Manjaro 17.1.10 的笔记本电脑上使用耳机上的暂停/播放按钮 (Plantronics BackBeat Pro 2)。他们还有“下一个”和“上一个”按钮，运行得非常好。我在 Spotify、Clementine 和 VLC 中尝试过它们，结果相同。

我读过 Arch wiki 页面：

从我发现的情况看来，我需要加载uinput内核模块。我读过的指南说它们应该放在两个不同的地方，但没有人解释要放入什么。

/etc/rc.conf

/etc/modules-load.d/uinput.conf \<-- （我认为这是用于旧方法？）

这是我在尝试寻找它时得到的结果：

[ibro@ibro-pc ~]$ lsmo |grep uinput
bash: lsmo: command not found
[ibro@ibro-pc ~]$ lsmod |grep uinput
uinput                 20480  1
[ibro@ibro-pc ~]$ grep uinput /proc/modules
uinput 20480 1 - Live 0xffffffffc048d000
[ibro@ibro-pc ~]$ grep uinput /proc/$(uname -r)/modules.builtin
grep: /proc/4.14.40-1-MANJARO/modules.builtin: No such file or directory
[ibro@ibro-pc ~]$ pulseaudio --version
pulseaudio 11.1

因此，假设这是问题，我需要弄清楚在哪里添加以及如何添加uinput 如果不是其他任何问题的解决方案

我想在 Linux 中添加两个额外的耳机功能支持。

  • 取下时智能暂停，戴上后继续播放
  • 主动聆听模式：检测到声音时暂停音乐。

当我跑步时，这两个都有与暂停/播放按钮非常相似的输出xev

这是实际的键盘暂停/播放按钮
