I am currently working on my own front end and would like to be able to control the volumes for the front vs rear speakers; but cannot find any info on how to do this.

This is for an Audigy 2 NX (usb). Does anyone have some references on how to accomplish this; I can access the master vol; wave; etc controls, but can't find the speaker controls (except in creative's surround mixer)....

Vb6 examples would be preferable; but anything (c/c++) or just some general info would be helpful.
