[RESOLVED] Play sound from Stream instead from File

I have this Sub-Routine which save a WAV-File and also plays it.
It uses the saved WAV-File for the Soundplayer. I would like to use the Stream itself to play (using the lines that are comented), however using it like that I get an error saying "Corrupted WaveHeader". Isn't the "BinWriter.BaseStream" the same Stream that is saved as my *.WAV file?
Can anybody tell me what I'm doing wrong.

vb Code:

Public Sub PlayWaveFile(ByVal WaveFileName As String, ByRef Buffer() As Short, Optional ByVal SamplesPerSec As Integer = 44100)
        Dim BinWriter As BinaryWriter = Nothing
        Dim Filestream As FileStream = Nothing
        Try
            Filestream = New FileStream(WaveFileName, FileMode.Create)
            'Create the writer for data.
            BinWriter = New BinaryWriter(Filestream)
            'Do stuff to create a real Wav-File
            WaveWriteHeader(BinWriter) 'write the Header
            For i As Integer = 0 To UBound(Buffer) - 1 'integrate the created Sound
                BinWriter.Write(Buffer(i))
            Next i
            WaveWriteHeaderEnd(BinWriter) 'write the Ending
            'Dim Sound As New System.Media.SoundPlayer(BinWriter.BaseStream)
            Dim Sound As New System.Media.SoundPlayer()
            Sound.SoundLocation = ReplayDateiPfad + "\Ping.wav"
            Sound.Play()
            Sound.Dispose()
            Sound = Nothing
            BinWriter.Close()
            Filestream.Close()
        Catch ex As Exception
            ErrLog_schreiben("PlayWaveFile", ex.Message, WaveFileName)
        End Try
    End Sub
