What happened when multiple audio players start at the same time?

Question

Hi,everyone!
I am developing a game, using JMF to play sound.
These sound are stored in mp3 files.
In order to decode mp3 files, I installed JMF and mp3-plugin( jmf-2_1_1e-windows-i586.exe , javamp3-1_0.exe).
In the Game, a background music play back repeatly.When EndOfMediaEvent happened, I setMediaTime(new Time(0)) and then start().It works well.
There are several sound-effects,may start at any time,
so 2 or more sounds may play back at the same time,
and then Strange things happened.
Those sound-effects, usually short, can not play back inextenso.
They lose some beginning part, the length of the part is not constant.
i.e. Audio should start at MediaTime 0, but now they start at MediaTime x, x >= 0,
not only that, sometimes, Audio process bar runs, but no sound heared.
I do not know what is happening.
So please help me, thanks a lot.
The way that I use Players:
initialize:
create realized players from mp3 files
prefetch them
finalize:
deallocate not null players
then close them
using:
player.setMediaTime(new Time(0))
then player.start()
My Environment:
Windows XP, java 1.4.10, JMF2.1.1, MP3-plugin1.0

This is very strange, difficult to guess the cause... never had such an issue. Normally when the object to which the audio is attached disappears the audio stops. So in your case going to a next slide should stop the audio of the previous slide. Same with object audio.
Do you have the different audio clips (one per slide) in the Library? Could you try to delete the audio on the slide and drag it again from the Library to see if you have the same result? And what happens when you attach the audio clip to an object on the slide (you can create a totally transparent rectangle with no stroke that will not be visible to attach the audio).
