* If this hint isn't specified to a valid setting, or libsamplerate isn't
* available, SDL will use the default, internal resampling algorithm.
*
* Note that this is currently only applicable to resampling audio that is
* being written to a device for playback or audio being read from a device
* for capture. SDL_AudioCVT always uses the default resampler (although this
* might change for SDL 2.1).
* As of SDL 2.26, SDL_AudioCVT now respects this hint.
*
* This hint is currently only checked at audio subsystem initialization.
