waveOutGetVolume (coredll)

coredll is for smart devices, not desktop Windows. Therefore, this information only applies to code using the .NET Compact Framework. To see if information for waveOutGetVolume in other DLLs exists, click on Find References to the right.

Returns the current system volume

C# Signature:

[DllImport("coredll.dll", SetLastError=true)]
protected static extern int waveOutGetVolume(IntPtr device, ref uint volume);

VB Signature:

Declare Function waveOutGetVolume Lib "coredll.dll" (ByVal uDeviceID As Integer, ByRef lpdwVolume As Integer) As Integer

User-Defined Types:



0 is off, 65536 is max volume.

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); }
