我正在尝试与 macbook pro 上安装的 debian 10 设置不和谐聊天。在discord 中列出了两个输入设备。默认和内置音频模拟立体声。我用的是默认的，效果很好。当我关闭计算机并在第二天重新启动时，discord 说它无法检测到来自我的麦克风的任何输入。我只想使用我的内置笔记本电脑麦克风。

sudo alsamixer：
我应该改变什么？
编辑：另外：为什么“麦克风”级别是空的？

首先我尝试：
felipe@SDF-1:~$ apulse
felipe@SDF-1:~$ sudo apt-get install tetraproc

它不起作用。
然后，我尝试：
felipe@SDF-1:~$ sudo apt-get purge pulseaudio

然后，

现在麦克风可以工作了。
答案2
只是做了sudo alsactl init然后将我的音量改回我想要的方式，一切都奏效了。
