Delay on first playsound |

Hello all,
I've noticed some delay with the first playsound in my application: everything in my application just stops, the cursor changes to the beachball and after a second or two finally the sound plays. Is it some kind of initialization routine (as it only happens once per session)? I guess it is not related to QT as those are sys7 sounds... I am using 4.5.2 on OS X 10.2.

Probably your app loads the sound from the resource fork; if your HD
went to sleep before, it has to spin up, that could cause a further delay. See the thread about the "Slow Tips Window", the RB IDE appears top have the same problem ;) Cheers, Frank+++ Andrea Suraci wrote: > > Hello all, > > I've noticed some delay with the first playsound in my application: > everything in my application just stops, the cursor changes to the > beachball and after a second or two finally the sound plays.

Thanks Frank, I've just read the thread about the tips window and I
guess this must be the same problem, and since it appears in the IDE itself it's probably a good subject for a bug report. Anyway, I'd be glad to be wrong on this.

I don't see what bug there is to report -- resources are loaded in a "lazy" fashion by the system, and unloaded (purged) too as the OS sees fit. It's just like virtual memory but on a smaller scale. Everything is working as it's intended to. Normally you don't see much hesitation when loading a sound, but of course if it has to spin up the hard drive then it will take longer. Not much we can do about that. But perhaps you could put in a feature request for some way to pre-load a sound (though I suspect you could already do this by setting the volume to 0 and playing it). Cheers, - Joe |

Thank you Joe, really helpful. I'll find a way to pre-load a sound in my splash screen.
