Hi Per, I solved this on linux with alsa. First i have created a file called ?asound.conf? which splits the sound card into different alsa plug devices (e.g stereo_out1, stereo_out2, ?, stereo_in1, ?) With pjsip it is possible to list all audio devices (pjsua_enum_aud_devs), so all previous created stereo devices are visible here. In order to connect these devices to the conference bridge you have to create sound ports with pjsip (pjmedia_snd_port_create, pjmedia_snd_port_create_player, pjmedia_snd_port_create_rec, See FAQ: https://trac.pjsip.org/repos/wiki/FAQ#multi-snd). The ids (playback/capture) needed for creating sound ports is the index of previous listed devices.
