Tips & Tricks:

To play a sound looping both SND_LOOP and SND_ASYNC flags have to be specified. Looped sounds only stop when PlaySound is called with pszSound set to NULL.

Sample Code:

    public static void Play (string strFileName)
    {
        PlaySound (strFileName, UIntPtr.Zero, (uint)(SoundFlags.SND_FILENAME | SoundFlags.SND_ASYNC));
    }

    public static void Play (byte[] waveData)
    {
        PlaySound (waveData, IntPtr.Zero, PlayFlags.SND_ASYNC | PlayFlags.SND_MEMORY);
    }
