PJSIP/PJSUA with Wolfson audio card

Former Member

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

    I wonder if it is a bitrate issue. A google for that error suggests it might be, but it was unclear.

    16000 is possibly unusual (I'm no expert). 8000 is often more likely. You could check your SIP software config file to see if you can set the bitrates used to something else.

    I could be completely wrong, but it is worth a try.

    Hi, thank you for the response. I could not configre this so I had to do some hard-coding. Given that I wrote the code correctly it did unfortunately not help.
