audio input not active open asio directx full duplex

Hi guys im a new member just bought yamaha MW10C with AI5 Cubase had problem setting up. After loading everything and download startup cubase this warning popup “Audio input not active, open Asio Diredtx full duplex setup dialogue check input port” which I did and set I/O. I import audio to test the playback and it only play in PC speaker but when I play my guitar nothing went in no wave and sound. How can I setup the input and output so I could record voice and guitar. Please help
Thanks
