The waveOutGetVolume function retrieves the current volume level of the specified waveform-audio output device.
Code examples:
WAV file player
Declaration:
MMRESULT waveOutGetVolume(
  HWAVEOUT hwo,      
  LPDWORD pdwVolume  
);
FoxPro declaration:
DECLARE INTEGER waveOutGetVolume IN winmm;
    INTEGER   hwo,;
    INTEGER @ pdwVolume
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.
Return value:
Returns MMSYSERR_NOERROR (0) if successful or an error otherwise.
My comment:
The low-order word of pdwVolume 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.
