No Output at windows 7 while using FL Studio

[Wladicorist1]

hello there :)

i thought about to ask you guys what my problem could be 


i use a Line 6 UX2 in FL Studio to get a better latency , today i thought about to stream on twitch for my friends
but the problem was 
as long as i use the UX2 in FL Studio the green bar at audio settings of windows (outputs) didnt move up 
so that means the sound goes from fl studio directly into my heaphones and dont even cross windows 7 

the big "BUT" 

i use the ux2 as my main soundcard so i watch youtube videos and talk to my friends 
so when i watch a video and hear the sound with the ux2 but the green bar at windows outputs move up 
so this means all these stuff except the fl studio sound 
i can stream and record with camtasia 8 

but why is it like that? what can i do? and what should i buy (what kind of interface)?


i post 2 pics 

1 with ux2 (no output at windows)
1 without ux2 (output at windows)
