Hi Alexei, Yes, the audio will stop, that is the correct behavior because current pjsua doesn't support Mac's input device monitoring (such as headphone plug/unplug). Having said that, this can easily be fixed by using CFRunLoop as your main loop (or putting it in your main thread). http://developer.apple.com/library/mac/#documentation/CoreFoundation/Reference/CFRunLoopRef/Reference/reference.html (To put it another way, coreaudio_dev does support headphone plug/unplug but it is the application's responsibility to ensure that the event is passed to CoreAudio). For illustration, modify your pjsua_app.c: add the necessary include file: #include <CoreFoundation/CFRunLoop.h> and add CFRunLoopRun() after the block "switch (menuin[0])", so it should look like this: switch (menuin[0]) { ... } // This should be at line 4507 if you use the latest SVN CFRunLoopRun(); After you rebuild, start pjsua and use the audio loopback command (cc 0 0) or simply make a call, then you can try plugging/unplugging your headphone. IMPORTANT NOTE: this is by no means a complete solution.
