Hi everybody ! I'm working on a on an i.MX6 (freescale) based product under a buildroot personnalized linux, and I try to use linphonec with it, but I've got troubles when I'm in call (voice is hatched). See the record I've made from the call : https://vocaroo.com/i/s1RrgXBSXIaT. The wireshark : https://www.cloudshark.org/captures/9fd82b8b4e60 To test and isolate the issue of hatched voice I played an
example sound from an asterisk server - I correctly establish a
call but every ~35sec the voice is hatched for 5sec. The codec
used for the call is PCMU, and the soundcard is an I2S with a
codec TI TLV320AIC3110 (http://www.ti.com/product/TLV320AIC3110).
Perhaps an important fact : Everytime I start linphonec I got these messages : ALSA lib conf.c:4738:(snd_config_expand) Unknown parameters 0 We think that the concern comes from the lower layers used by the linphone. Can there be incompatibilities with MediaStreamer2? Does all this bring up something that could help us solve our problem? Thank you for every single idea you'll give to us :) --
