Help with audio streaming


i got this issue : audio streaming problem. After pushing play in Cubase 8 Pro it takes like one second delay.

Drivers - up to date. I have tried all possible things to solve this issue - without any luck. Anyone got the similar problem or if there is already existing post please link me there.

Loving Cubase 8 Pro but i am solving this issue already 10 days without any luck.

Thank you so much for anyones help
