sound problem

[alaa]

Hi,
I'm having a sound problem. I have a class that plays a sound when I call a fucnction in that class. and also I have a sound that is always looping from the begining of the program (in the main program that is calling the class). Also i have another sound in there that playes once sometimes. The problem is that when I loop the sound from the class then I play the sound in the main program, the loop in the class stops. Here is a small part of the program explaining what i mean:
--------------------------------------------------------
class Avatar(viz.EventClass):
...
playSound():
self.obj.playsound('audio/sound.wav',viz.LOOP)



#in main program
viz.go()
avatar = Avatar(...)
bell = viz.add(...)
viz.playsound('audio/wind.wav', viz.LOOP) #this works fine all the time
....
avatar.playSound() #works fine till the next sound plays
....
bell.play() #now this plays and stops the other one
....
---------------------------------------------------------
I don't know if the problem is that the main program has a priorty for the sound, or is it that I'm doing something wrong.

I have another question, I keep getting "Interlace" in the output screen in vizard. What does it mean.

Thank you,
