Sony XBR-55X810C No Sound


Novice Member
Hello all, If this tread has been posted already I apologize in advance, I searched but could not find anything.

Here goes my issue.
I recently purchased a set top box MX10 android, I got it up and running but there is no sound unless I unplug the HDMI cable and plug it back in. I have used at least 4 different cables, from a standard one that came with the box, to a high speed with ethernet, same result. I switched HDMI ports, no luck. My PS4 and other apps work just fine.

I have even reset the tv still no luck.

I am thinking it's the tv because I plugged in the box to another tv and it worked fine.
Are there settings in the tv that I may have overlooked?

Any help would be greatly appreciated!
