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

    Has anyone got this working with the cirrus logic audio card and a raspberry pi 2? I am trying to use spkout speakers and the DCIM microphones with Jasper.

     

    I manually installed Jasper ontop of the cirrus audio card image as per the instructions from Jaspers website. The image was working fine before the install of Jasper.

     

    I have replaced the asoundrc file with the one built by ragnar.jensen in this post http://www.element14.com/community/roadTestReviews/1810. However I am pretty sure this is meant for the original woflson audio card and the raspberry pi b.

     

    When running jasper I get the welcome audio message played out through the raspberry pi headphone jack and then it fails with this error:

     

    No handlers could be found for logger "cmuclmtk"

    I've successfully used a Wolfson Audio Card with Gerrelt's (Truehl) Squeezeplug Logitech Media Server on a RPi B since it was first included in the Squeezeplug image.

    Recently and primarily using Ragnar's (excellent) instructions for setting up the WAC I have the Subsonic open-source web-based media streamer and jukebox working on another RPi B with a WAC.

    Now I am trying to get a RPI B to work with the WAC and Jasper. Unfortunately after many, many, many hours of trying and many fresh attempts I just cannot get it to install/run successfully. I suspect that not all the links in the instructions are pointing to where they should be.

    I would really appreciate it if someone could provide a working image that I could download. I just love the idea of using the on board microphones to pause/mute my music and I want top try and avoid having to go down the external USB mic route

    I will also post this on the Jasper forum and the Raspberry Pi  forum and will let all three forums if anyone is kind enough to provide a copy of their fully working image. Before anyone does I would probably recommend that they run populate.py again and enter through all the stages without entering their personal details.

    Certainly it would help CFC Farnell to sell their remaining stock of WACs which otherwise I would imagine would be languishing on the shelves of a warehouse somewhere until the decision was taken to send them to the tip,

    Today they are showing as having 2680 in stock which at the current price of £16.50 UK pounds is £44,220 UK pounds. Perhaps CPC Farnell could pay Ragnar something to create an image ?

    Thanks for reading,

    Thanks in advance

    Kind regards
