Yes, everything was fine on 10.5. I?m using pjsua-lib API from pjproject 1.0.3. No patches or any modifications either to pjsip or to portaudio. After upgrading to Mac OS X 10.6 users started complaining to this issue. The issue in my issue tracker: http://code.google.com/p/telephone/issues/detail?id=213 And just to be clear. I?m talking about plugging and unplugging headphones that are being connected to the standard microphone port. It?s not the same as when the list of available audio devices in the OS changes (for example, when user plugs in a USB headset). For the latter I?m using callbacks from the OS to reinit audio in pjsip.
