Greetings, Create a handler for the slider value changed event. Then in that event handler, set the sound volume of your player. Of course, make sure that whatever values you use in the slider correspond proportionately to the sound volume of your audio player. I am doing the same thing in my project and here is the code I use:

    private void OnSliderMusicVolumeValueChanged(object sender, RoutedPropertyChangedEventArgs e)
    {
        if (myMusicManager != null)
        {
            myMusicManager.Volume = SliderMusicVolume.Value; 
        }
    }

myMusicManager is just the name I gave to a class that wraps the wpf media player. Below is where I get and set the volume using the appropriate conversions.

    public double Volume
    {
        get
        {
            return myMusicPlayer.Volume \* 10; // myMusicPlayer is the actual wpf media player
        }
        set
        {
            myMusicPlayer.Volume = (value / 10);
        }
    }

I hope this helps, let me know if you have any more questions. Blitz
