PJSIP/PJSUA with Wolfson audio card

Former Member
Former Member over 11 years ago

I am trying to get a SIP client running on my PI with Wolfson audio card.

 

I can use aplay and arecord, work great but when I set up a call with PJSUA I get the following errors:

 

07:14:34.698pjsua_app.c  ..Turning sound device ON
07:14:34.698pjsua_aud.c  ..Opening sound device PCM@16000/1/20ms
07:14:34.707 alsa_dev.c  ...ALSA lib pcm_hw.c:326:(snd_pcm_hw_hw_params) SNDRV_PCM_IOCTL_HW_PARAMS failed (-22): Invalid argument
07:14:34.707pjsua_app.c  ..Turning sound device ON
07:14:34.707pjsua_aud.c  ..Opening sound device PCM@44100/1/20ms
07:14:35.292ec0x14005a8  ...Echo suppressor created, clock_rate=44100, channel=1, samples per frame=882, tail length=200 ms, latency=100 ms

07:14:35.293  pjsua_media.c  .Call 0: initializing media..

07:14:35.297 alsa_dev.c  ALSA lib pcm_hw.c:587:(snd_pcm_hw_start) SNDRV_PCM_IOCTL_START failed (-12): Cannot allocate memory

 

Anyone that can guide me in the right direction on how to get this running?

 

Best Regards

    Thanks for your post on the sample rate support for the ADC and DAC paths (specifically the analogue input and output paths).
     
    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.
    We will keep you posted on progress.
     
    Thanks.

    Any news on the driver front yet?

    just bought a original wolfson for my pi b, running on latest raspbian kernel (3.18) . My intention is to replace a server running darkice with a pi running darkice to cast radiopatapoe on http://radiopatapoe.nl:8000/transit
