AudioServicesPlaySystemSound not playing sounds

Question

I am playing a small .wav file using the AudioToolBox.

AudioServicesPlaySystemSound (soundFileObject);

But sometimes it is not playing.

Answer 1

Building on user1056521's answer, use the following code:

AudioServicesPlaySystemSoundWithCompletion(soundID, ^{
    AudioServicesDisposeSystemSoundID(soundID);
});

where soundID is the SystemSoundID value you got when you called AudioServicesCreateSystemSoundID().

The completion block ensures the sound was played and completed playing before it is disposed of.
