Get the name of the current audio driver.
const char* SDL_GetCurrentAudioDriver(void);
Returns the name of the current audio driver or NULL if no driver has been initialized.
The returned string points to internal static memory and thus never becomes invalid, even if you quit the audio subsystem and initialize a new driver (although such a case would return a different static string from another call to this function, of course). As such, you should not modify or free the returned string.
This function is available since SDL 2.0.0.
