2012 Macbook Air - no sound with Windows 10pro

I partitioned my 2012 MacBook Air with El Capitan and installed windows 10 pro using Bootcamp. I'm able to run Windows 10 no problem, however I can't get the sound to work.

Here's a screenshot of my device manager; how do I fix this? I've tried updating the drivers with bootcamp but each time I tried downloading them it fails, so now I'm seeking help from the nerdery.
