No sound from Macbook Air TV v 12.0.81460 to Windows TV 120.81460

This has ALWAYS been an issue way back when and I would have thought by now that this would be fixed.  As stated above I'm running macbook air (latest iteration) and using my Windows 8.1 to team view.  There is still no sound in this latest version between my Macbook and Windows.  Is this never going to be fixed?  Windows TV to Windows TV works just fine with audio.  Unfortunately I have to hear the sound for my job.  TV is a better product then what I use but if the sound is still an issue then I have to go back to what I was using.
