Visual effect transition from a card to another with sound on iOS

[Christian Langers]

Hello,

does anybody know of an elegant solution to have this transition done simultaneously ?

I'm using this :

visual effect "push left"
 if environment() is not "development" then iphonePlaySoundOnChannel getSound("load"), "Transient", "now"
go next

In the development environment and in the simulator the transition with visual effect and sound playing behaves as expected but on my device (iPhone GS - iOS 4.3.3) it doesn't.

You hear first the sound and then you get the visual effect...

??

Thanks,

Christian
