Trouble with one sound file stuttering

This one has me perplexed.   I’m playing a small sound file at game over and it appears to stutter at the beginning.   It’s smooth when I play it in QuickTime.

I’m playing on a reserved channel, and I’ve even tried different sound files in the same bit of code, and they play fine.   All exported at 41K, 16-bit, all small 1-second long sound effects.    

Only one of them appears to be starting late.

Anyone else ever seen (well, heard) anything like this?

Using the latest public release.

Are you pre-loading them or loading them right before the call to play?

Pre-loading.   .m4a for iOS, .ogg for Android, though I haven’t tested on Android yet.   This happens in the Simulator and my iPhone 4S.

It’s also the only sound playing besides an ambient sound looping on a separate channel.

What’s strange is that I can use any other sound file in its place and no stutter.     

I have seen this on a few areas myself, and for the life of me have no idea what it is caused from in the one game where i saw it happen 100% of the time i ended up just redoing all the sound files to mp3’s and the problem went away not to say that will resolve your issue as I have another game where it didn’t help at all.

Whatever the reason it has to do with the sound file itself, why or how they are different I have no idea as like you I am saving/exporting them all the same way so one would think they would be the same but there it is.

FYI one of the things I just tried as I was typing this was adding a half second delay to the end of the file and guess what, no start hiccup, so now I am really confused like the “size or length” of the file has something to do with this bug hmmmm
