After upgrading to Windows 8 on my 2011 MacBook Air running Boot Camp, I lost the ability to send audio over the DisplayPort connection. This was frustrating because I was used to leveraging my iMac in display mode and would prefer the speakers and mic of the iMac over the MacBook Air.

Thanks to this post I learned that I had to download and install latest display drivers from Intel. They include a display audio driver. Windows update will not help here.

This is the latest driver that worked for me. I’m now hearing audio over the DisplayPort, apparently this fixes the issue that arises from trying to send audio over HDMI as well.
