No Sound recorded

[DwainSnickles]

Awesome but I tried everything to try to record sound video works great no sound? running TestAppWinforms directly from source. Here is the code I'm using

private void RecordButton_Click(object sender, EventArgs e)
        {
            List<AudioDevice> inputDevices = Recorder.GetSystemAudioDevices(AudioDeviceSource.InputDevices);
            List<AudioDevice> outputDevices = Recorder.GetSystemAudioDevices(AudioDeviceSource.OutputDevices);
            AudioDevice selectedOutputDevice = outputDevices.FirstOrDefault();//select one of the devices.. Passing empty string or null uses system default playback device.
            AudioDevice selectedInputDevice = inputDevices.FirstOrDefault();//select one of the devices.. Passing empty string or null uses system default recording device.
            //var AudioOptions = new AudioOptions
            //{
            //    IsAudioEnabled = true,
            //    IsOutputDeviceEnabled = true,
            //    IsInputDeviceEnabled = true,
            //    AudioOutputDevice = selectedOutputDevice.DeviceName,
            //    AudioInputDevice = selectedInputDevice.DeviceName
            //};
            //These options must be set before starting the recording, and cannot be modified while recording.
            RecorderOptions options = new RecorderOptions
            {
