A variable controlling the default audio format.
Defined in <SDL3/SDL_hints.h>
#define SDL_HINT_AUDIO_FORMAT "SDL_AUDIO_FORMAT"
If the application doesn't specify the audio format when opening the device, this hint can be used to specify a default format that will be used.
The variable can be set to the following values: - "U8": Unsigned 8-bit audio - "S8": Signed 8-bit audio - "S16LE": Signed 16-bit little-endian audio - "S16BE": Signed 16-bit big-endian audio - "S16": Signed 16-bit native-endian audio (default) - "S32LE": Signed 32-bit little-endian audio
This hint should be set before an audio device is opened.
This hint is available since SDL 3.0.0.
