I'm attempting to allow my PJSUA-based app to automatically handle audio device changes, for example, plugging in a headset or removing the active headset. I can detect a change (under Mac OS X) via Core Audio's callbacks. I can get PJ to re-initialize by calling pjmedia_snd_deinit and pjmedia_snd_init. However, I'm having problems mapping the devices since all PJ has is a name. Unfortunately, names are not unique with USB devices. So I can have multiple of the same name. It would be handy if one could get the native device ID from PortAudio. Failing that, can I assume that the devices will always be in the same order that Pa_GetDeviceInfo returns them in? It contains a PaHostApiIndex which I can then use to get the native device ID via Core Audio?
