我已经在树莓派上安装了 wip,但是当我想使用它时出现此错误

[wit] initialized sox: 14.4.0
[wit] init state machine
[wit] initialized with device: default
[wit] ready. state=idle
formats: can't open input  `default': snd_pcm_open error: No such file or directory
[wit] couldn't open input device using alsa. Trying with coreaudio...
formats: no handler for given file type `coreaudio'
[wit] Failed to open input device
task '<unnamed>' panicked at 'called `Option::unwrap()` on a `None` value',
/home/martin/rust/src/libcore/option.rs:357

最佳答案

编辑 ~/.asoundrc 并添加以下内容:

pcm.!default {
    type asym
    playback.pcm {
        type plug
        slave.pcm "hw:0,0"
    }
    capture.pcm {
        type plug
        slave.pcm "hw:1,0"
    }
}



(取自“设置默认记录设备”下的 http://wiki.audacityteam.org/wiki/USB_mic_on_Linux。)

要确定 slave.pcm 之后应该写什么,请运行以下命令:
aplay -l
arecord -l

结果将分别指示 playback.pcmcapture.pcm 下应包含的内容。

例如,arecord -l 在我的机器上产生以下输出:
**** List of CAPTURE Hardware Devices ****
card 1: USBSA [Andrea PureAudio USB-SA], device 0: USB Audio [USB Audio]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
slave.cpm 旁边的文本应为 "hw:X,Y" ,其中 X 和 Y 取自上述输出的第二行:
card X: ..., device Y: ...
