Hi David,
The missing "Turning sound device ON" in your app log may mean that the
device is already on. When running pjsua the device may have been off
when you issued the "cc 1 0" command. I've browsed your logs and I can't
see any obvious reason why your app doesn't play sound. I would try to
verify that the sound device is generating callbacks and
conference::get_frame is being called. Perhaps turn on CONF_DEBUG in
conference.c.
