CoreAudio support was initially introduced by commit
62e29b39f4 as an experimental feature.
It played basic sounds, but suffered from drawbacks: it was controlling
the master channel, and therefore any sound played by ecore_audio would
shut down a previous sound (e.g. background music) for the time of the
sound being played. So that wasn't exactly great... Also, after some
time, some hangs have been reported when playing a sound on input. Most
of the time, it translated as a pause in the main loop (see T3797).
More recently (several months ago), ecore_audio with CoreAudio stopped
working during 1.19 development...
So... CoreAudio support on macOS has never been great. And now it's fully
broken. Instead of trying to revive the thing, let just use PulseAudio.
PulseAudio can be installed without any trouble on macOS thanks to
package managers such as Homebrew. Actually, the efl package provided by
Homebrew already provides PulseAudio as a dependency. And it actually
just works very fine. Dropping CoreAudio seems therefore a nice option:
removes unmaintained code, fixes bugs, and add features.
Summary:
Ecore_Audio now supports Apple's CoreAudio to play sounds read by libsndfile.
edje_multisense integrates this new feature to enable PLAY_SAMPLE on OS X.
Test Plan:
Compiles, links and installs fine on OS X.
Run terminology and elementary_test to hear sound played on user input.

Also remove the Classes section from the Ecore_Audio_Group, we don't
need it as the pages are linked automatically

Very hackish implementation and probably not needed as libsndfile
virtual IO can be used instead, though it's a little more complicated

Allows reading from and writing to wav, ogg, etc. files. Support for
virtual IO as well to allow playing sounds from eet, which will be
needed in edje multisense.

This is still very much a work in progress, so expect some issues. The
signalling is using ecore events for now - that will change to callbacks
you can register callbacks for events on specific Ecore_Audio_Objects.
EO wasn't there when Ecore_Audio started, but it will probably move to
that in the future.
Otherwise have fun, don't break it (too much) and please send bug
reports and feedback to me.
