[PD] rescan audio devices

[Dan Wilcox]

Short answer is "no."

Long answer is this functionality is missing in portaudio which Pd uses for it's default backend on most platforms. There is no way to rescan the connected devices within the library itself, although most of the OS-level components do (CoreAudio, ALSA, etc).

I have thought about implementing a direct CoreAudio backend for Pd on macOS which would add this support, but it's far down the list of things right now.

Best thing to do would be to bug the portaudio people...
