[已解决]alsamixer:This sound device does not have any capture controls

panpansuannai · 2020-08-04 18:21:54

arch笔记本播放声音正常，然而无法录音，运行alsamixer选择内置声卡后查看Capture时出现如题内容，在pavucontrol 选择Input Devices 里port只有一个 Analog Input,
Configuration 里Profile选的是Analog Stereo Duplex，在使用各种软件进行录音也不成功。比如使用simplescreenrecorder进行录屏的时候无论在Audio Input里选择哪一个
source都无法录入声音，以下是有关声音设备的一些信息，想问一下为什么声音录入不成功。谢谢。

硬件的话应该是没有问题的，毕竟笔记本是比较新的，而且在windows10下也可以正常录音。

描述现象而非结论：你是通过什么判断出来「无法录音」的？是程序报错了？还是程序崩了？还是录到了静音？还是录音按钮点不下去？

录到了静音（第一次发布求助，描述问题确实不够清晰，请见谅）

搜相关名称能搜到不少解决方案，但不确定你应该用哪个。
你的笔记本是什么型号的？
