I have been trying to make a VOIP calling device with a raspberry pi3 and MIC+ using PJSUA. There seems to be a bug when attempting to make/receive a call.
pjsua-armv7l-unknown-linux-gnueabihf: ../src/pjmedia/conference.c:1895: get_frame: Assertion `frame->size == conf->samples_per_frame * conf->bits_per_sample / 8' failed.To fix this: change /root/.asoundrc
options snd_rpi_googlevoicehat_soundcard index=0
pcm.softvol {
type softvol
slave.pcm dmix
period_size 320
buffer_size 10240
control{
name Master
card 0
}
}
pcm.micboost{
type softvol
slave.pcm dsnoop
period_size 320
buffer_size 10240
control {
name Micro
card 0
}
min_dB -10.0
max_dB 50.0
resolution 256}
pcm.!default {
type asym
playback.pcm "plug:softvol"
capture.pcm "plug:micboost"
}
ctl.!default {
type hw
card 0
}If it still does not work then refer to this:
