How to threading a couple of SoundPlayers to play synchronously?

[pourkascheff]

Hi all o7.
Consider a timer to perform

My.Computer.Audio.Play(My.Resources.Test, AudioPlayMode.Background)

A 500ms timer and 1000ms audio file will lead to cutting audio file and startover. I've tried threading but in a bad way, causing the UI freezing while it finishes the work.

Since twice of the duration is enough for audio length, Is it possible to toggle a boolean variable to perform each players/threads in a see-saw way?

Should I double the Media.SoundPlayer?

    Private Sub PlaySound1()
        Dim soundPlayer As New Media.SoundPlayer(My.Resources.test)
        soundPlayer.PlaySync()
    End Sub
    Private Sub PlaySound2()
        Dim soundPlayer As New Media.SoundPlayer(My.Resources.test)
        soundPlayer.PlaySync()
    End Sub

Or should I double the threads? Or should I do both???

    Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
        If ToggleSound Then
            SoundThread1 = New Thread(AddressOf PlaySound1)
            SoundThread1.Start()
        Else
            SoundThread2 = New Thread(AddressOf PlaySound2)
            SoundThread2.Start()
        End If
        ToggleSound = Not ToggleSound
    End Sub

Does Media.SoundPlayer even able to perform a sort of buffered "layering" of waves? Also simple form of "SoundPlayer.Play()" acts like first example.
Current results with 250ms timer for test: They keep playing slowly to finish entire file ignorantly, closing the form will not stop them (Depends on how long you spend x250ms while form was open, then stop runtime).
