如何配置 Pulseaudio 使笔记本电脑扬声器和耳机同时工作？

Question

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，扬声器就无法使用。

我尝试启用同时输出，删除 -switch-on-connect 和 -switch-on-port-available 模块并制作虚拟接收器，但没有任何效果。谷歌搜索只返回了相反的问题，人们不会在同一时间希望扬声器和耳机播放。

任何人都有任何解决方案？

Answer 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'

将其更改为禁用

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
