Cannot play more than 3 audio files?

[hyon]

After extensive searching on the net, I still could not find the answer to my problem. It may be very trivial to you guys, but help would be much appreciated!

I have the following code that works for 3 files/3 functions, but not with 4 files/4 functions. Why?

import appuifw
import e32
import appuifw
import audio

S1 = audio.Sound.open("E:\\Python\\chimes.wav")
S2 = audio.Sound.open("E:\\Python\\DingLing.wav")
S3 = audio.Sound.open("E:\\Python\\Bleep.wav")
S4 = audio.Sound.open("E:\\Python\\Ding.wav")

def playS1():
    global S1
    S1.play(1,0)

def playS2():
    global S2
    S2.play(1,0)

def playS3():
    global S3
    S3.play(1,0)

def playS4():
    global S4
    S4.play(1,0)
    
def quit():
    app_lock.signal()

app_lock = e32.Ao_lock()    

# Create a simple menu
appuifw.app.menu = [(u"S1", playS1),
                    (u"S2", playS2),
                    (u"S3", playS3),
                    (u"S4", playS4)]
    
    
appuifw.app.exit_key_handler=quit
app_lock.wait()

I've tried the code exactly as written by you and it works. It plays all 4 sounds.

Did you try with four different wav files?

I have a feeling it may be a hardware problem. I'm using a 5500.

Yes, you're right. The fourth file is the second one. Don't know why.
But interestingly, it plays 4 files if you have 5 (the situation is the same, the fourth one is actually the second one, but the fifth one is different). Strange.
