Parameters

hwo  IntPtr

A IntPtr to an open waveform-audio output device. This parameter can also be a device identifier.

refVolume  UInt32

T Pointer to a variable to be filled with the current volume setting.

The low-order word of this location contains the left-channel volume setting, and the high-order word contains the right-channel setting.

A value of 0xFFFF represents full volume, and a value of 0x0000 is silence.

If a device does not support both left and right volume control, the low-order word of the specified location contains the mono volume level.

The full 16-bit setting(s) set with the WaveOutSetVolume(IntPtr, UInt32) function is returned, regardless of whether the device supports the full 16 bits of volume-level control.

Return Value

Possible error values include the following:

BadDeviceId, InvalidHandleNoDriver, NoMem, NotSupported.
