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
我试图再次删除并安装 alsa，当我运行时
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。可以在此处找到 ALSA 信息脚本。
任何帮助将不胜感激。
