Pass IntPtr.Zero as the value for device if only one audio device in your pocket pc. !!!!Tips & Tricks: Please add some! !!!!Sample Code: uint ret = (uint)0; waveOutGetVolume(IntPtr.Zero, ref ret); This example above don't work for me. But I create this example below. public enum Volumes : int { OFF = 0, LOW = 858993459, NORMAL = 1717986918, MEDIUM = -1717986919, HIGH = -858993460, VERY_HIGH = -1 } [DllImport("coredll.dll", SetLastError=true)] internal static extern int waveOutSetVolume(IntPtr device, int volume); [DllImport("coredll.dll", SetLastError=true)] internal static extern int waveOutGetVolume(IntPtr device, ref int volume); public static Volumes Volume { get { int v = (int)0; waveOutGetVolume(IntPtr.Zero, ref v); switch (v) { case (int)Volumes.OFF: return Volumes.OFF; case (int)Volumes.LOW: return Volumes.LOW; case (int)Volumes.NORMAL: return Volumes.NORMAL; case (int)Volumes.MEDIUM: return Volumes.MEDIUM; case (int)Volumes.HIGH: return Volumes.HIGH; case (int)Volumes.VERY_HIGH: return Volumes.VERY_HIGH; default: return Volumes.OFF; } } set { waveOutSetVolume(IntPtr.Zero, (int)value); } } !!!!Alternative Managed API: Do you know one? Please contribute it! Documentation: waveOutGetVolume@msdn on MSDN
