just purchased the onkyo NR656 to upgrade a previous onkyo. getting an LG OLED this week. Both of these have HDMI with ARC. Basically now when i watch tv for news or a show use my tv speakers. When i watch a movie on disc or use my apple tv or play video game i get the sound through my receiver. Ise harmony remote to change all inputs and stuff. I only have 2 speakers and a sub as of now. My question is if i want to do the same thing am i even using the ARC HDMI. Does this turn off the tv speak when used. Component wise now have a directv tuner, a blu ray player, a dvd recorder, a nintendo switch and wii and an apple tv. Any help appreciated. Haven't had to touch the connections in like 8 years.
