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"
  }
}

[Fleker]

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

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 }

Same problem?

Platform: Raspberry Pi 3B+ OS: Raspbian GNU/Linux 9 (stretch) Attempting: Implementing Google Assistant on my RPi per instructions HERE.

All steps up to Step 5 under the heading "Authorizing your Raspberry Pi for the Google Assistant" work smoothly.

The ~/.asoundrc file allows the speaker and microphone testing outlined in the URL above to work properly.

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

Upon entering this line inside a python environment in the terminal (replacing <projectid> and <deviceid> with my personal specifics),

(env) pi@raspberrypi:~ $ googlesamples-assistant-pushtotalk --project-id <projectid> --device-model-id <deviceid>

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

I have attempted to modify my .asoundrc file by adding the 'rate 16000' bit as described throughout this thread. Not only do I get the same error when running googlesamples-assistant-pushtotalk commands after updating .asoundrc this way, but this also causes failure of the microphone testing procedures that were working before.

Updated ~/.asoundrc file:

pcm.!default {
        type asym
        capture.pcm "mic"
        playback.pcm "speaker"
}
pcm.speaker {
        type plug
        slave {
                pcm "hw:0,0"
        }
}
pcm.mic {
    type plug
    slave {
       pcm "hw:1,0"
       rate 16000
    }
}

Then (not in Python environment now), I run this command: arecord --format=S16_LE --duration=5 --rate=16000 --file-type=raw out.raw and get this error: Recording raw data 'out.raw' : Signed 16 bit Little Endian, Rate 16000 Hz, Mono ALSA lib pcm_params.c:2162:(snd1_pcm_hw_refine_slave) Slave PCM not usable arecord: set_params:1270: Broken configuration for this PCM: no configurations available

hco125, that's very starnge issue. I copied your config and tried to run it on my PI3, but had the same issue. Than I corrected your config like mine, so they looks similar. And had the same issue. I copied both to check them by online compairing and it showed no difference. I don't now what exactly cause the issue but it is definitely in your config. Try mine:

pcm.!default {
  type asym
  capture.pcm "mic"
  playback.pcm "speaker"
}
pcm.mic {
  type plug
  slave {
    pcm "hw:1,0"
    rate 48000
  }
}
pcm.speaker {
  type plug
  slave {
    pcm "hw:0,0"
  }
}

[yeunbok2g]

Thanks, sangdonyeom's way works for me.

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 } }

[pengzhendong]

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 } } Thanks srdayne

Ubuntu works. Raspberry PI OS should install pulseaudio and reboot first.

sudo apt-get install pulseaudio
