sounddevice.PortAudioError: Error opening RawStream: Invalid sample rate [PaErrorCode -9997]

I keep getting that message everytime i try to run googlesamples-assistant-pushtotalk
And i have correctly configured ~/.asoundrc because the speaker and the microphone works when i run speaker-test, arecord and aplay.

This is the ~/.asoundrc file if you need it...

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"
  }
}

Looks like a sample rate issue between the code and your hardware device.

[newtonsart]

Is there any way to fix that?

These are my devices:
Speaker
Microphone

[SrDayne]

Hi. Try add "rate" in asound config, like here:

pcm.mic {
  type plug
  slave {
    pcm "hw:1,0"
    rate 16000
  }

[newtonsart]

@SrDayne still having the same problem

[SrDayne]

Try different speach-to-text software. For example, Snowboy. But, I'm on 98% sure, that problem in microfone settings. And when you recorded by arecord, what frequency did you use?

[amrky]

i have the same issue :/
please help

sounddevice.PortAudioError: Error opening RawStream: Invalid sample rate [PaErrorCode -9997]

Hi. First of all, what is your microfone model? Second, same problem = same solution. Try this, but I'm not sure about correct frequency:

pcm.mic {
type plug
slave {
pcm "hw:1,0"
rate 16000
}

[sangdonyeom]

I have the same problem, please give me solution this
on taskbar, sound mark has x
the strange thing is speaker and min are work very well

but when I write down like "googlesamples-assistant-pushtotalk --project-id friday-xxxxx --device-model-id friday-aed12-friday-xxxxxx"
error appear like this

Ensure that your microfone support 16kHz frequency of sound. If no, try to find out what frequency it supports.

Yes, my mic support to frequency 100-16kHz

and I also insert rate 16000 in .asound

but still have problem.

Problem can be also with speaker. For example, I'm using bluetooth speaker, and when it turned off, assistant gives me the same error. Show your whole error log.

now I retry 4times but I don't understand why uu

[sangdonyeom]

just add "rate 16000" for output like below
pcm.!default {
type asym
capture.pcm "input"
playback.pcm "output"
}
pcm.input {
type plug
slave {
pcm "hw:1,0"
}
}
pcm.output {
type plug
slave {
pcm "hw:0,0"
rate 16000
}
}
