PlaySound will only play up to a 48.69s wav file

[BriansBrain]

Using API PlaySound I can't get it to play wav files longer than 48.690 seconds.

My system is WinXP Service Pack 2 - VB6 SP5

I need to use the SND_SYNC Flag.

Normal PCM wav files at 44100Hz, 16 bit Mono and from the Hard Drive.

*NOTE* wav files up to > 48.690s play perfect till the end.

A 48.700s or longer wav file will NOT play till the end.

BTW: In an old W98se system this problem does NOT happen.

===================================================================

Here is my simple wav file tester I have made in VB6 to show the problem I am getting.

General Declarations

Option Explicit
Private Declare Function PlaySound Lib "winmm.dll" Alias "PlaySoundA" (ByVal lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long

Private Sub Form_Load()

Dim TimerNOW As Date

Const SND_NODEFAULT = &H2 ' Stops the SystemDefault sound playing if this file cannot be found
Const SND_SYNC = &H0      ' Do not return until the sound has finished playing.
Dim wFlags As Long
wFlags = SND_SYNC Or SND_NODEFAULT

TimerNOW = Timer
PlaySound App.Path & "\Tone 44100Hz, 16 bit Mono, 48.690s.wav", ByVal 0&, wFlags
Debug.Print "File Length: 48.690s <-> Play Time: " & Format(Timer - TimerNOW, "00.000") & "s"
DoEvents

TimerNOW = Timer
PlaySound App.Path & "\Tone 44100Hz, 16 bit Mono, 49.000s.wav", ByVal 0&, wFlags
Debug.Print "File Length: 49.000s <-> Play Time: " & Format(Timer - TimerNOW, "00.000") & "s"
DoEvents

TimerNOW = Timer
PlaySound App.Path & "\Tone 44100Hz, 16 bit Mono, 60.000s.wav", ByVal 0&, wFlags
Debug.Print "File Length: 60.000s <-> Play Time: " & Format(Timer - TimerNOW, "00.000") & "s"
DoEvents

TimerNOW = Timer
PlaySound App.Path & "\Tone 44100Hz, 16 bit Mono, 90.000s.wav", ByVal 0&, wFlags
Debug.Print "File Length: 90.000s <-> Play Time: " & Format(Timer - TimerNOW, "00.000") & "s"

These are my results from the Debug.Print on WinXP system...
File Length: 48.690s <-> Play Time: 48.798s
File Length: 49.000s <-> Play Time: 00.703s
File Length: 60.000s <-> Play Time: 22.656s
File Length: 90.000s <-> Play Time: 82.641s

I can't see what the problem is in my code.

BTW: My 4 wav files were made with Cool Pro and ALL work perfect to the end in every other player
Here are the 4 wav files incase someone wan't to try them.

Please note I can't upload them to the Forum even one file at a time as I get this ...
