look in the MMedia.hlp for the MixerObject refernces.
 you may also find some VCL code on the net in the line of
 TMixer., TAudioMixer ect..
  how it works  is like a family tree., you must enumerate the controls
starting
from the base of the master Volume.Record, or Other Panels. or you can
specify directly specific control.
    since you have a multiple channel card then you should  have multiple
 mixer objects,  you first need to Enumerate the Mixer list to pick the channel
you
want to work with, this will give you a Mixer ID to use in the MixerOpen which
gives you a handle to be used in the remaining mixer calls.
 this things from getting a list of controls , Reading or write their values.
