Recently reinstalled windows 10 which fixed a lot of problems I had earlier but now I am running into a new problem. I have my MBA in clamshell mode connected to my TV and the sound goes through the laptop instead of the TV speakers. I have a 2010 MBP that runs windows 7 and no such problem ever existed. I've opened up the sound devices and nothing. The only oddity that I see is under device manager a sound device labeled as "High Definition Audio Device" is flagged and has an error "The device cannot start: Code 10". I've googled and saw some people having similar issues but I wasn't able to resolve the situation myself. Any ideas would be appreciated! Thanks!
