Roku Soundbar No Signal on Vizio TV

I have a Roku Smart Soundbar connected to a Vizio 4K TV with an HDMI cable. When I power on both devices to use, the Vizio TV doesn't detect the video signal from the Roku Soundbar. I can hear audio from the Soundbar as I click through the menu. The quick fix is to change the input on the TV to something else and then back to the Soundbar. Anyone have a solution to this?
