Wasapi audio quality

Question

Im new to using Wasapi in Naudio and Im having n issue with the sound quality. About 1/10 times the audio will sound perfect when I record and the other 9 times it will be fuzzy. I was wondering if there is any reason for this.

Here is my code i'm using to record the audio:

    public void CaptureAudio(String Name)
    {
        capture = new WasapiLoopbackCapture();
        capture.Initialize();
        w = new WaveWriter(Name, capture.WaveFormat);
        capture.DataAvailable += (s, capData) =>
        {
            w.Write(capData.Data, capData.Offset, capData.ByteCount);
        };

        capture.Start();

    }

    public void StartRecording(String Name)
    {
        new Thread(delegate(){CaptureAudio(Name); }).Start();
    }

    public void StopCapture()
    {
        capture.Stop();
        capture.Dispose();
        w.Dispose();
    }

The problem turned out to be xbox music or windows media player running in the background, apparently they hog all the sound cards resources.
