My LG 50 inch Model: 50NANO75UPA HDMI Arc stopped working with my Vizio soundbar. It worked very well when I first connected it until this morning. I purchased an extended warranty, but is there a known solution before I send out for help? It is definitely the LG Tv, and not the soundbar because I used to have a Samsung soundbar, which worked only for about a week before the HDMI Arc stopped working and I switched over to the Optical. Now even the Optical does not work That's why I bought a Vizio.
