I have bad news for you. I wasn't able to solve the issue. It got a bit better after a bios update, but I still had glitches sometimes.
I kept having high latency for ASPI.sys and I couldn't fix it. I tried many new drivers and for many apparently it is the Intel Graphics card that causes trouble. I've read that others have solved it by installing the 46.29 driver for the Intel HD 630 graphics card. You can download it from station-drivers. For me it didn't work unfortunately.
I had a gig and my sound was lagging all the time. Then I had enough and sold the thing. Probably it will get solved in the next months with some driver updates, but I could't wait that long.
Now I bought a MacBook Pro and I wish I had done that in the first place.
