Hello!

So as the title says. I am certain that the Rocker works, since it does work on another TV.

The optical plugins seem to be present on the TV, but there is just no sound. On the TV menus it's mentioning "optical / HDMI ARC" and seperately also PCM.

I'm attaching the pictures. http://imgur.com/a/Ae4vo

Thank you for any advice! I'd love to blast the Rocker while watching GoT! :D
