Windows 7: How to change the Sound of application + Device ?

hi folks
as you can see in the screen shot of my desktop the volume control panel. What i want to know that i want to increase the volume of all 3 mention application on full and want to use the volume increase and decrease by only using the device volume
The million dollar question is how can i do that ? i have tried alot to do it but helpless and unable to do so if i increase the volume of any application the device volume also increases it self so what to do ? wait for your reply thx a bunch

If I understand what your trying to do correctly you just need to drag all the volume sliders individually to the Max then if u drag the device volume the rest should follow.

what i want here is i want to use only the device volume to lower or increase the volume, where application volume remain at full but when i try to do this all of them move simultaneously which i dont want at all
