如何配置Pulseaudio使筆記型電腦揚聲器和耳機同時工作？

我有一台裝有 Ubuntu Eoan 的筆記型電腦。單聲音卡、單耳機插孔。

我想同時使用筆記型電腦揚聲器和耳機（沒有特別的原因，只是因為），但是一旦我插入耳機，揚聲器就變得不可用。

我嘗試啟用同時輸出，刪除 -switch-on-connect 和 -switch-on-port-available 模組並建立虛擬接收器，但沒有任何效果。谷歌搜尋只返回相反的問題，即人的問題不是想要揚聲器和耳機同時播放。

有人有解決辦法嗎？

輸出amixer -c0：

答案1

透過 ALSA 中的此設定插入耳機時，揚聲器將靜音

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

將此更改為殘障人士

amixer -c0 sset 'Auto-Mute Mode' Disabled

並保存ALSA設置，以便ALSA在系統恢復時保留設置

sudo alsactl store

答案2

連接耳機後，alsamixer在終端機中運行，F6按 選擇您的音效卡，然後：

  1. 停用Auto-Mute Mode：移至Auto-Mute Mode，然後向下鍵停用。 （nik gnomic 的答案也適用於此）
  2. 取消靜音Speaker並將音量增加至 100%：移至Speaker，按M取消靜音，然後按 UP 或 PgUP 增加音量。

阿薩混合器

這些都是對我有用的步驟。
