Getting error InvalidParameter calling waveInOpen

Getting this error every time calling WaveInEvent.StartRecording. Method MMDeviceEnumerator.EnumerateAudioEndPoints(DataFlow.Capture, DeviceState.Active) returns info about my microphone. Method WaveInEvent.GetCapabilities(0) returns 2 channels with many SupportedWaveFormat. This issue is not direct related to NAudio, tried my code with DllImport - same result. Can anybody help me? Windows 7 SP1 x64

Nо solution found. In my case the reason was - Kaspersky antivirus on operator PC, so i have added additional message to error handler. Sample code:

catch (Exception ex)
{
    string msg = "Error when starting recording";
    var mmex = ex as NAudio.MmException;
    if (mmex != null && mmex.Result == NAudio.MmResult.InvalidParameter && mmex.Message.IndexOf("waveInOpen") > -1)
        msg += "warning about AV software";
    _logger.Error(ex, msg);
}

Sorry for issue closing without comment.
