How do I figure out if Windows is currently playing any sounds?

How can I figure out if Windows is currently playing any sounds through the primary audio device? I need to know, so that I can make my program automatically adjust its volume.

You could use CSCore.
Download it right here -> http://cscore.codeplex.com/

Paste these lines on a console project.

using System;
using CSCore.CoreAudioAPI;

namespace AudioDetector
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(IsAudioPlaying(GetDefaultRenderDevice()));
            Console.ReadLine();
        }

        public static MMDevice GetDefaultRenderDevice()
        {
            using (var enumerator = new MMDeviceEnumerator())
            {
                return enumerator.GetDefaultAudioEndpoint(DataFlow.Render, Role.Console);
            }
        }

        public static bool IsAudioPlaying(MMDevice device)
        {
            using (var meter = AudioMeterInformation.FromDevice(device))
            {
                return meter.PeakValue > 0;
            }
        }
    }
}

Play a music be it on YouTube, Music Player, etc...
Run the program.
It automatically notifies(true/false) if there is an audio currently being played or not.
