I am developing an application for internal use. Part of the setup is
to set volume controls to certain levels during the setup. I need a
program that will set the following levels automatically when
executed:

PLAYBACK MODE:
volume (all the way down) but unmuted
Wave (moderate)
Line - mute
Mic all the way up and unmuted
everything else - mute

RECORDING MODE:
line - moderature 
Mic - all the way up, 
Mixer, low-moderate, SELECTED (box "X"ed)

This is a sort of strange application -- what is happening is that the
user is playing back an audio file on their computer, listening to the
file, and talking into a microphone, and both the microphone and the
audio file is sent as part of a VoIP application to a remote user.

I stumbled around Google in an attempt to figure this out myself, but
I am not a very good programer. I did find the following resources
that may be of use:
