Latency sound issues and frame drops - AN515-55-55DW

JoSaZa

Hello, i am mostly using my laptop as a "dock" station. I have everything connected on it, monitor, mouse, keyboard, headset and i have noticed when i am not using my laptop screen, i get sound crackling (music, in-game, everywhere) i noticed i have sound latency issues and also while gaming it causes very sudden and brief frame drops, it like stutters for a second. I noticed when i open my laptop screen (still with all my devices connected) but still playing on my gaming monitor this suddenly stops, but once i close the laptop screen the problems come back. So i ruled out the problem of, "using too many devices and draining power". 

Brief explanation:
Full gaming setup connected to laptop and laptop screen is open - NO PROBLEMS
Same scenario except laptop screen is off - Frame drops and sound crackling

Is there any setting maybe that when it detects i am not using my laptop screen it makes my devices/driver/whatever not work properly?

Thanks in advance!
