Mute microphone on Windows 7

I have an problem with muting the mic on an windows 7 machine. But all the code i have found dosen't run ore it's not doing anything the runned. Have is it done for an Windows 7 machine using C# code. I just need an on/off solution. The DDL file works also with Win x64bit. But i thing that i creates an error another place. 

        mixers.Recording.Lines.GetMixerFirstLineByComponentType(
                     MIXERLINE_COMPONENTTYPE.SRC_MICROPHONE).Volume = 0;
            if (!mediaElement1.CheckAccess()) mediaElement1.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, (Action)delegate { mediaElement1.Play(); });


            if (MessageBox.Show("Incoming Call from: " + string.Format(e.RemoteParticipant), "Video Chat Call", MessageBoxButton.YesNo) == MessageBoxResult.Yes)
            {
                mixers.Recording.Lines.GetMixerFirstLineByComponentType(
                             MIXERLINE_COMPONENTTYPE.SRC_MICROPHONE).Volume = 1;
                if (!mediaElement1.CheckAccess()) mediaElement1.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, (Action)delegate { mediaElement1.Stop(); });
                _currentConversation.StartVideo();

            }'

If error occurs at if (MessageBox.Show("Incoming Call from: " + string.Format(e.RemoteParticipant), "Video Chat Call", MessageBoxButton.YesNo) == MessageBoxResult.Yes) and says {"Arithmetic operation resulted in an overflow."}

You can use Audio Switcher Api https://www.nuget.org/packages/AudioSwitcher.AudioApi.CoreAudio/4.0.0-alpha5

Code is quite simple:

private async void btnMute_ButtonClick(object sender, EventArgs e)
{
    var audioController = new CoreAudioController();
    var devices = await audioController.GetDevicesAsync(DeviceType.Capture, DeviceState.Active);
    var device = devices.FirstOrDefault(x => x.IsDefaultDevice);
    if(device != null) {
        await device.SetMuteAsync(!device.IsMuted);
    }
}

this might help: Windows Mixer Control in C#

Good luck :).

EDIT: It can also mute certain devices if I'm right.
