Use this function to get the name of a built in audio driver.
const char* SDL_GetAudioDriver(int index);
|index||the index of the audio driver; the value ranges from 0 to SDL_GetNumAudioDrivers() - 1|
Returns the name of the audio driver at the requested index, or NULL if an invalid index was specified.
The list of audio drivers is given in the order that they are normally initialized by default; the drivers that seem more reasonable to choose first (as far as the SDL developers believe) are earlier in the list.
The names of drivers are all simple, low-ASCII identifiers, like "alsa", "coreaudio" or "xaudio2". These never have Unicode characters, and are not meant to be proper names.
This function is available since SDL 2.0.0.
