Remarks
Passing in a device name of NULL requests the most reasonable default (and is equivalent to calling SDL_OpenAudio()). The device name is a UTF-8 string reported by SDL_GetAudioDeviceName(), but some drivers allow arbitrary and driver-specific strings, such as a hostname/IP address for a remote audio server, or a filename in the diskaudio driver.
SDL_OpenAudio(), unlike this function, always acts on device ID 1.
