need help with my volume control

[poe35 0]

hi,

 

i have a cambridge soundworks with 1 sub and 2 sat's. It's great but i have a promble with it. I have the volume controler and it does work without using the volume control on the taskbar. next to the time. So inorder to control the volume i need to use the volume control on the task bar and the cambridge controler has to be from min to about 2 or there is no sound. I don't have a soundcard but a on-board 5.1 Legacy Audio Drivers. I need help on how i can get rid of the volume button and use the cambridge control for volume control. Is it the drivers??

 

Thanks
