TV Loses sound when enhancing HDMI to 4k Enhancement.

by Brandon Earnsberger / May 15, 2016 7:55 AM PDT

I Just bought a 65in Sony 65x810c 4K. I have ATT Uverse. I updated the hdmi cords that ran behind my call, about 20 feet in length. Picture and sound worked great. However when I select to Enhance to 4k through the input options. I get picture but no sound.

Any help would be appreciated

Back to Sony.

It's their code and TV so report this bug and then decide if this is the make/break decision to keep or return the set.

My thought is that you are enhancing some copy protected content. I can't confirm but it's possible this is https://en.wikipedia.org/wiki/Cinavia

You might get around this by running the content to a receiver that will handle the sound and then the video passes through the receiver and the TV only has to deal with the video.

No I am only trying to enhance the content from the att U verse box

I'm sure Sony and ATT will point fingers. A receiver will likely be the cure.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
