mini2440的WINCE6.0，怎样播放声音呢？

由于友善提供的WINCE6内核，不包括媒体播放器、解码器等模块，sndPlaySound函数用不了，大家用什么方法来播放声音呢？

try this:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        PlaySoundFile("startup.wav")
    End Sub

    Private Declare Function WCE_PlaySound Lib "CoreDll.dll" Alias "PlaySound" _
            (ByVal szSound As String, ByVal hMod As IntPtr, ByVal flags As Integer) As Integer


    Public Shared Sub PlaySoundFile(ByVal soundFile As String)
        Const SND_ASYNC = &H1
        Const SND_FILENAME = &H20000
        WCE_PlaySound(soundFile, IntPtr.Zero, SND_ASYNC Or SND_FILENAME)
    End Sub

Micro 2440 使用这个方法无法播放wav,  问题出在哪里？
