无音频（I/O）Manjaro Linux KDE

我在大学使用笔记本电脑录制讲座（我有诵读困难症）。直到最近，我才相信我的笔记本电脑是通过我为其配的外置麦克风录制的。然而，它总是显示麦克风未插上，并默认为内置麦克风。今天早上我尝试使用 HDA-jack-retask 修复它。然而，似乎我已经完全禁用了所有音频，我尝试重新启动。

我运行的是 manjaro linux KDE 版本（最新版本），我必须安装 Pulse 音频，因为它不是预装的，我尝试通过内置音频重置为默认值，通过尝试播放 spotify 和 youtube 检查是否通过 pavucontrol 和音频录音（这两个都无缘无故地跳来跳去，但没有音频）

通过 ksysgaurd 杀死 alsa 也杀死了 pulse，所以它现在以同样的方式重新启动：speaker-test -c 2 -l 1 -D hw:0

但没有听到任何声音

答案1

我不知道以上所有内容意味着什么，我使用 Linux 还不到 24 小时，到目前为止遇到很多问题，其中之一就是没有音频，下面是我为使音频正常工作所做的事情，经过几个小时的摆弄，幸运的是：

操作系统：Manjaro KDE 最新版本
声卡：Realtek HD sound 或 (ALC889)

  1. 开始添加/删除软件 Octopi
  2. 搜索 PulseAudio Volume Control 并安装
  3. 启动 PuslseAudio 控制并转到配置选项卡
  4. 高清音频控制器/选择离开
  5. 内置音频/选择模拟立体声双工（不插电）（不可用）
  6. 祈祷它有效
