Problem with recording audio with UR12

Hi, i’ve recently purchased a UR12 and ive installed the Yamaha steinberg USB driver and made the necessary connections for the guitar according to the manual, but i am unable to record my guitar audio with the cubase elements program. Ive also tried opening up amplitube as a virtual amp but i am unable to hear any sound. Btw im using the headphones jack instead of the speakers jack. Is there anything that im doing wrong??

Thank you very much
