Hi Esben, Assumed you are using the SVN version, pjsua on linux is configured to be linked with host API OSS & ALSA without JACK while the devices you are looking for seem to be JACK, so I guess that's why... To enable JACK host API in the pjsua, I think you can start with: 1. modify the makefile (third_party/build/portaudio/os-auto.mak), e.g: export CFLAGS += -DPA_USE_JACK=1 export PORTAUDIO_OBJS += pa_jack.o 2. create a pa_jack.c in the third_party/build/portaudio/src, which actually refer to the real pa_jack.c from PortAudio (you can see other files in above directory how to do that).
