Speaking of paths (as was one lista): I had a "resources" folder at the same level of my stack so the pathnames I used (both hardcoded and programmatically set) were of the form "resources/mySound.aif". When I compile the app, I copy the resources folder into the same folder as the app and everything works just fine.
The problem? It's a mathematical or timing error in Rev (or QT?) - maybe something to do with rounding but here is what I found: I needed to have a sound play completely before proceeding with another sound and, during the handler, some images are being displayed and hidden. So I use the following line of code to cause the handler to wait until the sound in complete.
wait (the duration of player "player1") / (the timeScale of player "player1") seconds
What sometimes happens (I eventually discovered by looking at the player object's properties) is that something causes the audio file to stop playing prematurely, maybe as little a 5% or less from the end of the file. The next time the handler tells the player to start playing, only the last few % of the file plays. It sounds like the audio vanishes and then starts back up at the end but it's really just the end of the file that plays. The "wait..." code makes it seem as if everything is timed properly (because currentTime is ignored). The next time you run through the handler, everything plays fine because the sound file is back at the beginning (well, really the end but playing it from the beginning is really the only course open at this point).
I've also found that the "wait..." line of code, above, does not always result in the correct amount of time passing before the handler proceeds. The result is sometimes less so the sound stops prematurely when some other line of code executes in the handler.
The "fix" I put into place is as follows:
wait (the duration of player "player1") / (the timeScale of player "player1") + .2 seconds
--note the "+.2" I added. Sometimes I can use .1, it appears. This guarantees that any small error in timing won't cause the handler to continue prematurely.
then I add:
set the currentTime of player "player1" to 0 -- that's a zero
-- this forces a "rewind" of the player in case something causes a premature halt to the sound.
-- now the next time I play the sound, it's ready to play from start to end.
I went through multiple levels of Cat Skinning to nail this SOB but it works and, hopefully, Rev2 (or maybe OSX 10.2.3 or QT6.1) will resolve it.

From: Barry Levine <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED]I have a stack with a player object. No matter how I assign the fileName property or play the sound (via transcript or the message box), I have at least one audio file that will not play some of the time. My audio files are all AIF 22KHz, 16bit, mono. It was suggested that I first set the fileName to empty and then re-set the property to the correct name. I've tried this. Also tried playing the "empty" player before re-setting the fileName property. No luck. I've tried "pre-playing" the sound (playing it with the playLoudness set to 0) and then playing it at the proper volume. No luck. I've found some consistency: Play the sound the first time and it will fail (even if played twice in one handler). Play the same sound the second time (without changing the fileName to something else and back again) and it plays fine. Change the fileName property to some other audio file and it plays (with the other sound). Change it back to the original fileName and it will fail to play. Play it again (another event triggering the same handler) and it plays fine. I've even tried playing the sound TWICE in one handler (with no "wait" delay between) and the same consistency applies. What can I do to work around this? Another audio format? Will Rev 2.0 resolve it? Thanks, Barry
