I would like to mirror either my smartphone or labtob to my vizio. when I directly connect the laptop to the smart tv w/surround sound I get no tv sound at all, I also have a Sony 5.1 surround sound and it works for sound only when theres a disk in. I checked hdmi cables, they nay be old,
Have you been connecting to the TV itself and then the TV is connected to the Surround Sound? Or have you actually made sure that the laptop is connected to the Surround Sound? Which is what it will need to make the sounds work.
