Hi, I have a problem with the micro. It's impossible to record sound when I am using pjsua_recorder_create(). However, if I use the recfile sample, there is no problem. But the recfile sample doesn't use the conf bridge. I have the same problem, when I am using pjsua_call_make_call(). And each time, I don't forget to connect the recorder (or the call) to the sound device by using pjsua_conf_connect() in the right way... so it's not the issue. If you have any idea... Regards, R?my.
