Hi Jean, I closed out your other question as a duplicate so as not to cost you more, we'll continue here.
Can you tell me the model number of the tv?
Initially, you want to have the soundbar OUT port connected to the hdmi2 port on your tv that should be the arc port.
The bluray and cox box you can connect to the remaining ports.
Can you give that a try, then go into the tv menu under Audio and look for a speakers or external setting, when choosing that it should give you an option to choose the soundbar instead of the tvs internal speakers.
Let me know if that works for you.
