#11374: macOS: sound output does not follow "active output" selected from audio
applet

 == What did I do?

 - Selected internal speakers as a default audio output on Mac (via audio
 applet in the status bar)
 - Started ScummVM
 - Switched default audio output to something else (Bluetooth speakers,
 monitor output)

 == What happened?

 ScummVM continued to use internal speakers.

 == What should have happened?

 ScummVM should have switched to the new default audio output.

 == Environment

 - ScummVM 2.1.1, official build
 - macOS 10.14

 == Notes

 There are applications on macOS that do give the user an ability to
 explicitly direct audio to some output (e.g. videoconferencing
 applications), but they come with configuration dialog to select the
 output.

 Mac applications that do not have this functionality ought to follow the
 default output, even if it changes at runtime. I believe CoreAudio hides
 it from the applications — most likely ScummVM is missing this piece of
 integration by using some lower-level API.
