IOS AudioServicesAddSystemSoundCompletion callback incurring a 1 second delay?

I do not know about the delay, I have never experienced that. But maybe you could try this . It is objective-c wrapper for SystemSoundID and some of its assosiated functionss, including completion callback.

It should be easier to use this instead of C functions.

Sorry to those reading this, but I used a support request with Apple to get to the bottom of this due to time constraints and you wouldn't believe the answer...

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
