There are also a bunch of third-party utilities like nircmd or setvol that allow you to control the volume via the command line or hotkeys.
nircmd is generally cool, in addition to volume, it can do a lot of things.

If you are interested, audacity (an open-source music editor) used to make the portmixer library, it is designed to work in conjunction with the portaudio library. Portmixer is included with the audacity source.
This portmixer is designed to change the volume, and this is a cross-platform option.
Changing the volume is not a trivial process, and it is not done with a single call to WinAPI.
If you want, you can take the sources of portmixer and modify them for yourself.
