如何配置Pulseaudio使笔记本电脑扬声器和耳机同时工作？

我有一台装有 Ubuntu Eoan 的笔记本电脑。单声卡、单耳机插孔。

我想同时使用笔记本电脑扬声器和耳机（没有特别的原因，只是因为），但是一旦我插入耳机，扬声器就变得不可用。

我尝试启用同时输出，删除 -switch-on-connect 和 -switch-on-port-available 模块并创建虚拟接收器，但没有任何效果。谷歌搜索只返回相反的问题，即人的问题不是想要扬声器和耳机同时播放。

有人有解决办法吗？

输出amixer -c0：

答案1

通过 ALSA 中的此设置插入耳机时，扬声器将静音

Simple mixer control 'Auto-Mute Mode',0
 Capabilities: enum
 Items: 'Disabled' 'Enabled'
 Item0: 'Enabled'

将此更改为残疾人

amixer -c0 sset 'Auto-Mute Mode' Disabled

并保存ALSA设置，以便ALSA在系统恢复时保留设置

sudo alsactl store

答案2

连接耳机后，alsamixer在终端中运行，F6按 选择您的声卡，然后：

  1. 禁用Auto-Mute Mode：移至Auto-Mute Mode，然后向下键禁用。 （nik gnomic 的答案也适用于此）
  2. 取消静音Speaker并将音量增大至 100%：移至Speaker，按M取消静音，然后按 UP 或 PgUP 增大音量。

阿尔萨混合器

这些是对我有用的步骤。
