No sound & some games only loading their launchers

The First time i open a game the sound usually works. But if I quit and open another it won't work and either has no sound, or super stuttering sound then drops.

Also, the controller only works in games like team fortress 2 hl2, cs go, etc once in actually in the game. Also games like far cry 3 simply load u play, but don't actually launch the game.

Shield TV + windows 10 660 ti
I updated sound card too.

I'm pretty sure that I'm on the newest beta version, but I'm not what version is the newest for both the shield android app and the GeForce experience?

Is there anything else I can try? I'd really like to get this working.
