So I recently purchased a line 6 pod studio ux2 interface. The problems I am having is the interface is not picking up on my guitar (the meters do not move at all). I also get no sound from my speakers. I tried different cords and a different guitar but its the same for everything even though they all work fine on my amp. I am running the interface on my macbook pro air OS El Capitian, like I stated I've used multiple cords and guitars. If anyone can help me it would be greatly appreciated.
