Have you read the documentation?

AudioServicesPlaySystemSound

Plays a system sound object.

void AudioServicesPlaySystemSound (
   SystemSoundID inSystemSoundID
);

Discussion This function plays a short sound (30 seconds or less in duration). Because sound might play for several seconds, this function is executed asynchronously. To know when a sound has finished playing, call the AudioServicesAddSystemSoundCompletion function to register a callback function.

This stackoverflow question might help you to learn how to use this callback.
