Main Volume control from Delphi 3 ?

In the absence of a multimedia forum...

Is there a way I can programically control the main volume
from a Delphi program ?

I have managed to switch the sound off/on using a couple
of MCI API calls but I'm dammed if I can find a way to
vary the volume...  HELP !!!!
