Audio 如何修复：设备列表：270：未找到声卡（Ubuntu服务器18.04）？

我试图用usb麦克风捕捉一些音频，我收到了标题中提到的错误消息

以下是一些（希望相关）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

输出为：

**** 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

我猜这意味着Ubuntu正在识别我的声卡。可以找到ALSA信息脚本

任何帮助都将不胜感激
