Logic Pro X guitar recording issues

I am using a Line 6 Toneport GX to record my guitar tracks using Logic Pro X on a 2014 Retina macbook 13"

I don't know why but my volume needs to be maxed out for me to even hear any guitar signal (by pressing volume up on the keyboard) Then there's this horrendous buzzing constantly heard when i am not playing any notes.

What is the deal??? The guitar tone itself sounds terrible no matter which amp preset I am using.
