Hi, I write an application based on the "simpleua.c" example. And I have a problem using speaker and microphone at the same time ... Creating and connecting the media port through pjmedia_snd_port_create_player (),pjmedia_snd_port_create_rec() and pjmedia_snd_port_connect() is ok. But if I connect the player and the recorder, I have no more sound on the speaker during the call. If I connect only one, it's all ok. I use the PCMU codec and both sound ports have the same settings. Host is Linux. I made the basic tests as proposed in the "troubleshooting" section, but haven't found something. Any idea what's going on or test I could make ? Thanks for help David -------------- next part -------------- An HTML attachment was scrubbed...
