Try this

<Runtime.InteropServices.DllImport("winmm.dll")> _
    Public Shared Function waveOutSetVolume(ByVal hwo As IntPtr, ByVal dwVolume As UInteger) As Integer
    End Function

Private Sub TrackBar1_Scroll(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TrackBar1.Scroll
         
        Dim NewVolume As Integer = ((UShort.MaxValue / 10) * TrackBar1.Value)
        ' Set the same volume for both the left and the right channels 
        Dim NewVolumeAllChannels As UInteger = ((CUInt(NewVolume) And &HFFFF) Or (CUInt(NewVolume) << 16))
        ' Set the volume 
        waveOutSetVolume(IntPtr.Zero, NewVolumeAllChannels)
        
    End Sub

If that what you want, take it. If not, ignored it and no complain
