UR22 interface doesn’t sound

Hello, i got an UR22 interface wich i’be used a few years ago with no problem. I kept it saved for a time and now when I plug a mic or an instrument the only thing that sounds its a white constant noice.

USB Light is on, and also de peak light of Input2.

Its not a setting up trouble beacouse ibe checked a few times. I read the manual and maybe I used bad the HI-Z button and that ruined the input 2 and that its messing all up.

Please I need help, I’m from Chile and the Support Services here are very bad, so I prefer to fix it myself with someone’s Help.
