Arris: Randomly no sound from TV

Arris (Set-top Boxes): Randomly no sound from TV
I have At&t U-verse Set-top Box connected to XBOX one X through HDMI in and HDMI out to Samsung TV. I also have optic audio out from XBOX one X to a Yamaha AVR. When the Set-top Box goes to sleep and I try to turn on the TV again
I lose the TV sound and I have to turn the XBOX off and then on to get the sound back. The XBOX one X is sit to to to TV when it turn on. This also happen when I watch movie on XBOX or play games. I exchanged XBOX but I still have the same problem. I had a
google TV box hooked the same way I hooked the XBOX before and I did not have this problem

Why do Mics/Party still not work?

Randomly:

No sound through mic or TV, sound through TV only, sound through mic and TV, sound through kinect only, sound through mic but sounds like kinect.

Also, still have to turn on part chat after accepting an invite, randomly turns off your chat without notification if not playing same game. Randomly turns off all sound/chat during games and then randomly returns all sound and chat after game ends.

This was perfected on 360. They have the ability. What is the problem. Stop trying to reinvent the wheel Microsoft.
