If this is a test mixer only, so maybe it does not matter that much, but 
anyway:

Loopback controls are usually labeled

"Line Playback Volume"
"Mic Playback Volume"

And outputs:

"Headphone Playback Volume"

For line outputs, I'm not sure if the right thing is

"Front Playback Volume",
"Line-Out Playback Volume", or
"Line Out Playback Volume"

Eh, is there a loopback control from the headphone?
