PortAudioError(errormsg, err) sounddevice.PortAudioError: Error opening RawStream: Invalid sample rate [PaErrorCode -9997]

[JawsOrca]

Hi All,

Sorry stupid beginner questions.

I'm trying this project on a Raspberry Pi 3.

I have a cheap usb webcam with a mic and a usbpowered mic driven speakers.

I'm entering: python -m googlesamples.assistant.grpc.pushtotalk

And I keep getting an error:

(env) pi@raspberrypi:~ $ python -m googlesamples.assistant.grpc.pushtotalk

.asoundrc =

pcm.!default {

}

ctl.!default {

}

If I do the speaker test I hear the test.

If I test record this works too.

Sorry I've tried several suggestions from stackoverflow etc but nothings working and I'm getting a bit lost. I'm starting to suspect that the webcam just isn't compatible with this project but hope you guys can help before I give up!

Thanks in advance, p.s I'm a right novice with the pi and linux :(

sounddevice.PortAudioError: Error querying device -1

can this be fixed using some configurations ?

[Fleker]

The asoundrc doesn't seem to be in the right format https://developers.google.com/assistant/sdk/guides/library/python/embed/audio

[shivasiddharth]

@Fleker , Even with a properly configured .asoundrc and asound.conf, there seems to be this Portaudio problem and its only with the gRPC API. This occurs if you give a delayed speech input or speech input quickly after triggering. Please find below as to what happens and when.

1. Trigger the assistant and immediately provide a speech input.
   Portaudio Error.

2. Trigger the assistant and wait for a second before providing speech input.
   No Portaudio error and GA works fine.

3. Trigger the assistant wait for a couple of seconds and provide a speech input.
   Portaudio error.

4. Trigger the assistant and dont give any speech input.
   Nothing happens and assistant times out as it should.

This issue occurs even with the provided pushtotalk (unmodified and using enter key as trigger).

Thanks.

I have the same problem @Fleker any updates on this ?

[proppy]

@JawsOrca @karrarmaher @shivasiddharth @moham96 can you give a try to #188 ?

[moham96]

@proppy I got the pushtotalk sample to work once but I wasn't able to replicate the results.and after I deleted my env and tried to install the packages again I got import errors as outlined in #189

[bimbim2401]

Hello, i am using a raspberry with a just boom amp hat connecting together and an usb mic, i have my proper asound.conf which looks like this :

pcm.dsnooper {
type dsnoop
ipc_key 816357492
ipc_key_add_uid 0
ipc_perm 0666
slave {
pcm "hw:1,0"
channels 1
}
}

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

And i have install a python script made by @shivasiddharth for an google assistant , the "ok google" is working great but the pushbutton.py ( https://github.com/shivasiddharth/GassistPi/blob/master/src/pushbutton.py) returns this log ( i have change the pin indicated in the file with another one as it uses by the amp hat). Can you please help me, i have create an issue on the git project but no solution for the moment to resolve the bug shivasiddharth/GassistPi#356

i see in the fix #188 some precisions but do not know how to implemented this fix in this project or maybe it s a format problem of the asound file or with the mic...
