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。單音效卡，單耳機孔。

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 模組並製作虛擬接收器，但沒有任何效果。Google搜尋只返回相反的問題，即人們不希望揚聲器和耳機同時播放。

任何人有任何解決方案？

輸出amixer -c0：

通過 ALSA 中的此設置插入耳機時揚聲器靜音

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

將此更改為已禁用

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

連接耳機後，alsamixer在終端中執行，按下F6以選擇您的音效卡，然後：

1. 禁用Auto-Mute Mode：移動到Auto-Mute Mode，然後向下移動以禁用。（nik gnomic 的回答也適用於此處）
2. 取消靜音Speaker並將其音量增加到 100%：移動到Speaker，按M取消靜音，然後按 UP 或 PgUP 增加音量。

這些是對我有用的步驟。
