Hey Shayne, > Have you applied Samuels patch to 1.4 to activate 'legacy' device APIs? The one from http://code.google.com/p/siphon/downloads/list Yupp. I also verified that in pjmedia_aud_subsys_init() the driver count is 1 including only the one pjmedia_legacy_factory .... But in the end it was a stupid spelling error in an #ifdef :-) Sorry, for the noise. One problem still left though. But that looks more like Mac tool chain problem. While audio works fine now for the device, the very same build still fails for the iPhone simulator. I am still trying to figure out why it can't find the headers files from the SDK frameworks. Seems like someone came across the same issue: http://stackoverflow.com/questions/1626579/compile-error-for-iphone-simulator cheers -- Torsten
