I've searched extensively for an answer to this question and can't find anything to help. I have a early 2014 MacBook Air 13" connected to an Elgato Thunderbolt 2 dock and all works perfectly other than the fact that i can't watch any video (Youtube, Netflix, Hulu, etc.) nothing will play. The video will load i'll get a the first frame of the video to show but nothing plays. I've connected a mid 2013 11" air to the same setup and the same issue occurs. On occasion i'll get to watch through 1 video then the issue will occur. I've switched thunderbolt cables around and unplugged the device. This will allow for a video to play momentarily (could be 1 video could be less), then the problem comes back. Anyone have any ideas? I have the Elgato driver installed. The screen i'm using is a LG 34UM95 ultra wide.
