我试图使用usb麦克风捕获一些音频，但收到了标题中提到的错误消息。
以下是一些(希望是相关的(命令的输出：
arecord -l
arecord: device_list:270: no soundcards found...
ls /cat/asound*
ls: cannot access '/cat/asound*': No such file or directory
lspci -v

我试着再次删除和安装alsa，当我运行时
sudo arecord -l

我想意思是Ubuntu正在识别我的声卡。ALSA信息脚本可以在这里找到。
如有任何帮助，我们将不胜感激。
使用aplay l后，我患上了aplay: device_list:268: No sound card found...。根据下面的Ubuntu故障排除指南，我安装了apt install linux-generic，重新启动后，它在ova的Ubuntu服务器20.04中的VirtualBox中找到了我的声卡。
