Wolfson audio card + Jasper ?

Question

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

Hi Frederick, Jasper works fine with the Wolfson audio card using the .asoundrc found at the link below. It allows alsa to play/record in any rate format. I also removed the hw: references in boot.py and mic.py. The original error you got is due to the wolfson card throwing an error on the samplerate. Raspberry Pi and Karaoke Machine (Wolfson Pi Use and its Limitation) Here is where they admit the unintentional behavior: Re: PJSIP/PJSUA with Wolfson audio card Element14: "I can confirm your observation on the sample rate limitation. From our perspective it wasn’t the intention to limit the audio ADC and DAC sample rates to above 32k. At the moment we are investigating an update to the drivers which will allow full 8k to 192k support for the analogue inputs and outputs."

Hi Frederick, I did not use jasper on the pi, only on PC. But some time ago I found this. Maybe it works for you. http://stevenhickson.blogspot.de/2013/06/voice-command-v30-for-raspberry-pi.html

This might help not sure though: sudo apt-get install libasound2-plugins What jack are you using for speakers? This is how I got it working but I think I need to solder on the pins and hook up some speakers that way http://www.raspians.com/wolfson-jasper/
