Basic input level monitor - ASIO not showing up

[emanueltilly]

This is probably a incredibly dumb question, but I'm trying to get input levels of my Dante Virtual Soundcard (ASIO) but its not showing up at all when I enumerate devices. Using NuGet package 1.10.0. Is there anything I can do to my code to make it work?

    private WaveIn recorder;

    public Form1()
    {
        InitializeComponent();

        recorder = new WaveIn();
        recorder.StartRecording();

        MMDeviceEnumerator en = new MMDeviceEnumerator();
        var devices = en.EnumerateAudioEndPoints(DataFlow.Capture, DeviceState.Active);
        comboBox1.Items.AddRange(devices.ToArray());
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        if (comboBox1.Text != "")
        {
            var singledevice = (MMDevice)comboBox1.SelectedItem;
            try { progressBar1.Value = (int)(singledevice.AudioMeterInformation.PeakValues[0] * 100); } catch { }
            try { progressBar2.Value = (int)(singledevice.AudioMeterInformation.PeakValues[1] * 100); } catch { }
            try { progressBar3.Value = (int)(singledevice.AudioMeterInformation.PeakValues[2] * 100); } catch { }
            try { progressBar4.Value = (int)(singledevice.AudioMeterInformation.PeakValues[3] * 100); } catch { }

        }
     }

The MMDeviceEnumerator will find all WASAPI devices. To enumerate ASIO devices, use the AsioOut class instead

Ah I see. Now I'm finding my ASIO devices, but I can't seem to get the PeakValues for the audio meter when using the AsioOut class?

With ASIO, you have to generate your own peak values, by capturing sound and examining the sample values. It's a very low-level driver format.
