Sdl2 from 2.0.6 no audio

Hello to all!
Using precompiled mingw sdl2 2.0.6 (2.0.7 and 2.0.8) the static libSDL2.a causing no audio.
Any help?
The project is:

and the issue topic is:

latest working SDL2 2.0.5 (tested) from 2.0.6 no audio

Is this a bug?
Thanks…

Fixed using SDL_OpenAudioDevice() instead of SDL_OpenAudio() with SDL_AUDIO_ALLOW_FREQUENCY_CHANGE | SDL_AUDIO_ALLOW_CHANNELS_CHANGE
