Declaration:

Declare Function waveOutGetVolume Lib "Winmm" (ByVal wDeviceID As Integer, dwVolume As Long) As Integer

Parameters:

* hwo Handle to an open waveform-audio output device. This parameter can also be a device identifier. * pdwVolume 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 function is returned, regardless of whether the device supports the full 16 bits of volume-level control.

Returns:

Returns MMSYSERR_NOERROR if successful or an error otherwise. Possible error values include the following. MMSYSERR_INVALHANDLE Specified device handle is invalid. MMSYSERR_NODRIVER No device driver is present. MMSYSERR_NOMEM Unable to allocate or lock memory. MMSYSERR_NOTSUPPORTED Function isn't supported.
