audio - 如何修复 : device_list:270: no soundcard found (Ubuntu server 18. 04)？

Question

我试图使用 USB 麦克风捕获一些音频，但我收到了标题中提到的错误消息。

这是一些(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
00:1b.0 Audio device: Intel Corporation 7 Series/C216 Chipset Family High Definition Audio Controller (rev 04)
Subsystem: Hewlett-Packard Company 7 Series/C216 Chipset Family High Definition Audio Controller
Flags: bus master, fast devsel, latency 0, IRQ 29
Memory at f7c30000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: snd_hda_intel
Kernel modules: snd_hda_intel

我尝试在运行时再次删除并安装 alsa

sudo arecord -l

输出是:

**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC221 Analog [ALC221 Analog]
    Subdevices: 1/1
    Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 2: ALC221 Alt Analog [ALC221 Alt Analog]
    Subdevices: 1/1
    Subdevice #0: subdevice #0

我想这意味着 Ubuntu 正在识别我的声卡。可以找到 ALSA Info 脚本 here .

如有任何帮助，我们将不胜感激。

在使用 aplay l 后，我有 aplay: device_list:268: No sound card found...。按照下面的 Ubuntu 故障排除指南，我安装了 apt install linux-generic 并在重新启动后它从 ova 的 Ubuntu Server 20.04 中的 VirtualBox 找到了我的声卡。
