Question

我正在尝试在我的Pi 3b +上安装google助手，并且一切正常，没有错误，我的麦克风和扬声器正在工作，我的.asoundrc是正确的

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

并且我遵循了很多教程，并且确实像它们一样，还在线尝试了其他一些修复程序，但是都没有修复此问题。有人可以帮忙吗？

这是整个消息

Answer 1

可以测试一些东西，我尝试将速率16000放在pcm.speaker下，现在可以了

$ ssh me@118.247.237.49 -p 8822
ssh: connect to host 118.247.237.49 port 8822: Connection refused

Answer 2

对于仍然存在此问题的人：

确保您编辑 /etc/asound.conf 文件。我被卡住了，因为我编辑了 /home/pi/.asoundrc 文件。

如何修复sounddevice.PortaudioError。打开RawStream时出错：无效的采样率[PaErrorCode -9997]
