Cubase AI7 unable to record

Hi guys and gals I have installed Cubase AI7 on a
Windows 7 laptop
I’m using a focusrite 2i4 as my hardware input however after setting up the device in setup and adding the input/output buses. I’m unable to record,it is not giving me the recording sound wave. Also when I switch my amps on which i’m using as the outputs for play back. I get a tinny digital type noise coming out of them.
I believe I have installed the relevant drivers that came with the focusrite 2i4.
Any Ideas ?
