Thanks everyone for the reply.
I was looking for the solution of this case and found this topic I can't hear audio in youtube when Cubase is open. - Cubase - Steinberg Forums where ShikiSuen said " PC is a terrible choice if you want to use built-in audio to run ASIO applications. I suggest you to return your laptop and get a Mac unless you have your special purposes or necessities of using PC. In such case, an external audio interface with discrete ASIO support is of vital importance. You could simply buy a Steinberg UR22-mkII."
Then i bought a Steinberg UR22-mkII immediatly and was happy until scrolled down. My heart broken, I will received the soundcard tomorrow 
To chakkman: Can you please show me how to do in detail? Thank you very much.
