Hi, The 'passive port' term in conference bridge means conference bridge won't call get/put_frame() of the port, it is useful for port that has its own clock to call get/put_frame(), e.g: sound device port and master port. So in this case, your application doesn't really need to call get/put_frame() manually, since the sound device port will do. Here is a bit more detail on the implementation, all you need to do is adding your second sound device (and so on) to the conf bridge as passive port, the conf bridge will return a pointer to pjmedia_port here, then just connect the 'just added' sound device to that pjmedia port using snd_port_connect(). Then your app can do connecting "legs" using conf_connect/disconnect_port() as usual. That's all. Another alternative is using splitcomb port with reversed channel. However the passive port trick should be simpler.
