谢谢你的帮助，我尝试了几个星期来解决这个问题，但毫无成效。我唯一能听到声音的方法就是插上耳机。不幸的是，我再也没有耳机了。
这是我用买来的不同零件组装的一台电脑。我唯一的输出设备是Hyperx Cloud 耳机它不再工作了。
操作系统：Lubuntu
显卡：Radeon rx 580 dual oc 8GO
处理器：Ryzen 5 2600
主板：asRock B450 pro4
我的屏幕是戴尔的P2210一，好像没有外音。
我插上普通耳机就可以了，但我需要更大的音量；也许我应该买一套外置扬声器？
这里有几个输出，我不确定如何读取它们的输出

使用 pavucontrol 时，我可以设置声音的上升和下降，但我从未听到过。
我现在能做什么？我感到很绝望
谢谢你的帮助
