i have still my sound problem (see: Volume Down don`t work with Aureon 7.1 Firewire )

with the app setvolume.exe and getvolume.exe from frodos download-site and two windows-scripting-host files, who i have write, i can set the volume up and down.
i have bind this two scripts into the apps-menu and they work fine. but i want to start them from the main skin (i want to bind them with the volume up and down button).
how can i do this?
