The Windows API functions for midiout and waveout devices for
controlling volumes of individual speakers of a standard stereo sound
card are known as,

midiOutSetVolume Lib "winmm.dll" Alias "midiOutSetVolume" (ByVal
uDeviceID As Long, ByVal dwVolume As Long) As Long, and

waveOutSetVolume Lib "winmm.dll" Alias "waveOutSetVolume" (ByVal
uDeviceID As Long, ByVal dwVolume As Long) As Long, respectively.

Where can I find those for controlling the the volumes of individual
speakers of a 4 speaker sound card ( eg., front left, front right, rear
left and rear right)?
