Change audio from OpenAL to AVAudioEngine for Apple

Is your feature request related to a problem? Please describe.

Hi,

Xcode is warning about OpenAL deprecation (macOS, iOS and tvOS).

Example:

/Users/paulo/Developer/workspaces/cpp/axmol/core/audio/AudioPlayer.cpp:78:9: warning: 'alDeleteBuffers' is deprecated: first deprecated in macOS 10.15 - OpenAL is deprecated in favor of AVAudioEngine [-Wdeprecated-declarations]
        alDeleteBuffers(QUEUEBUFFER_NUM, _bufferIds);

Describe the solution you'd like

OpenAL was deprecated. Make axmol compatible with AVAudioEngine.

Thanks.

can switch to AX_USE_ALSOFT=ON

[paulocoutinhox]

I can use this inside my CMakeLists.txt using set(AX_USE_ALSOFT ON)? Or have another way to do this?

[rh101]

set(AX_USE_ALSOFT ON CACHE BOOL "Use ALSOFT on apple" FORCE) should work. Just remember to clear the [build_folder]/CMakeCache.txt and re-run the cmake command after you do this (via axmol build ... etc.).
