I have a 65” Toshiba fire tv and I am trying to hook it up to a Visio sound bar, model # M213ad-k8. It is an M series all in one bar. It appears that I am connected properly to my tv according to a Visio tech but I cannot get any sound from my tv. I have enabled CEC and yet there is still no sound. Is there anything else on the tv that I need to enable for my sound bar to work? I also should add that I have a cable box connected to the tv, as well.
