Wolfson audio card + Jasper ?

fvan

Hi,

 

has anyone been able to get Jasper (Jasper | Control everything with your voice ) to work with the Wolfson audio card ?

 

I tried getting it to work with two different approaches and ended up with the same result (which is something good I suppose).

  • Took the Wolfson image and manually installed Jasper software
  • Took the Jasper image and manually installed Wolfson drivers/kernel

 

Jasper is working via the command line, but when trying to use voice control, I get some (Alsa related?) errors.

 

Expression 'PaAlsaStream_Configure( stream, inputParameters, outputParameters, sampleRate, framesPerBuffer, &inputLatency, &outputLatency, &hostBufferSizeMode )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2762
Expression 'r' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2013
Expression 'PaAlsaStreamComponent_FinishConfigure( &self->capture, hwParamsCapture, inParams, self->primeBuffers, realSr, inputLatency )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2650

 

Full log attached.

 

Thanks!

Frederick

    Thank you I think I am getting closer here's the error without the edits

     

     

    pi@raspberrypi ~ $ aplay /home/pi/jasper/static/audio/jasper.wav

    ALSA lib pcm_direct.c:1658:(snd1_pcm_direct_parse_open_conf) Unknown field the

    aplay: main:682: audio open error: Invalid argument

     

     

    OK it plays if I sudo

     

    aplay /home/pi/jasper/static/audio/jasper.wav 

     

    Is that typical?

    Thank you all.

     

    It's a hack but I just added sudo aplay to mic.py and boot.py image all is well in my world now.

    Jasper starts up, asks how he can be of service and such, but when I try to give it a command, nothing happens image

     

    Edit: ok, I get the beep beep when I say Jasper, and it replies image (had to increase input volume for DMIC)

    But my english must be so bad that it never answers correctly when I ask the time ...

    Ok, it just seems to have difficulties understanding me, but it works.

     

    If I repeat nice and slowly, it seems to work! Thanks everyone!

    Hey Frederick,

     

    I'm trying to get voice command by Steven Hickson to work with the Wolfson audio card. It seems like i'm having similar issues to what you experienced with Jasper. I currently can play music just fine through the pi, just when I try to set up voice command i am not able to get audio to output. I changed the .asoundrc file on the pi thinking it may be a similar issue but am still not getting any audio. I was wondering if you had and ideas of how I might be able to troubleshoot this problem.

     

    Thanks,

    Ryan

    Hi Ryan,

     

    as you read here, I was struggling a lot to get Jasper to run with Wolfson also.

     

    I think the best approach would be to create a new discussion and have others participate there, as this will create the best visibility on your problem.

    Also try to attach log files/screenshots/anything that seems useful to help troubleshoot the problem.

    What did you do to get the Jasper + Wolfson working after you encountered all the error messages? I am encountering similar messages as to what you did, but am not having any luck resolving them. I'm getting the following:

    For context to my previous post, I followed the RoadTestReview Todd put together. Todd, if you have any thoughts here they'd be appreciated as well.

    Hi Drew,

     

    have you gone through all the feedback from Todd and Will in this thread ?
    One of the last things I fixed was this: http://www.element14.com/community/message/118485/l/re-re-wolfson-audio-card-jasper#118485

    I've been over this post many times, and many others image. I did install libasound2-plugins. The other thing I'm realizing is that when I play the jasper.wav sound using aplay I get the 'Playing WAVE '.../jasper.wav' : Signed 16 bit...' message, but it never terminates and I don't hear anything. I have to ctrl-c to get it to stop.
