Question

I need to control the main computer volume in vb.net. I have searched the web and tried all the examples I could find. None of the have worked.

Does anyone have some snippets of code that work with vb.net 2010 to control volume?

Thanks

I found an answer. Its uses Nirsoft’s NirCmd (32-bit , 64-bit)

Public Class Sound
    Dim nircmd As String
    Const MAXVOL As Integer = 65535

    Public Sub New(ByVal nircmd_location As String)
        nircmd = nircmd_location
    End Sub

    Public Sub setVol(ByVal level As Integer)

        Dim p As New ProcessStartInfo
        p.FileName = nircmd
        p.Arguments = "setsysvolume " & (MAXVOL * (level / 100)).ToString
        Process.Start(p)

    End Sub
End Class

You can then use somthing like

Dim vol As New Sound(path_to_nircmd)
vol.setVol(50)
