Hello, I've been working with pjproject 1.0.x and want to upgrade to the latest version. How can I replace the audio back-end in pjsua with my own using the new audio subsystem? With the old version I configured pjproject with '--enable-ext-sound' and supplied rules to build the audio back-end in user.mak. As I understand it all available audio back-ends are hard-coded in audiodev.c (PORTAUDIO, WMME, SYMB_VAS, SYMB_APS, and SYMB_MDA), and there is no way of dynamically add a new audio driver. Or am I missing something? Do I have to modify audiodev.c to get my own audio back-end in pjsua? I want to modify as little code in pjproject as possible to ease maintenance. Thanks, Dan
