Steam Inhome Streaming audio and resolution issues

When I try to stream the game trough IHS i get NO audio at all and the game will have a black box all around the game window rather than go full screen unless I set the game itself as windowed on the server machine.

This server streams perfectly a lot of other demanding games such us Diablo3, Divinity, Starcraft 2, Dota 2 with audio and everything but not this one.

Is this my issue or does anyone else have it?

I'm using HW encode on a nVidia GTX 680 and Win7, my client is a Macbook Pro and i get the same result both on Yosemite and Win 8
