hdmi ARC - can anyone explain?

[tony.silveira]

i’m so confused.

i have an lg c1 oled that i have my ps5/series x plugged directly into to benefit from the high frame rate.

i’m trying to feed audio back to my onkyo 626 receiver but i’m lost.  tv hdmi 2 is eARC which is plugged into my receivers main out.  i have all the options turned on on both ends (tv/receiver) but no receiver sound?

am i confused on how ARC works?  if i select hdmi 2 on the tv, then i’m no longer in my ps5 input. 

i have an optical cable in order as a back up.

usually just a stupid setting that messes everything up.

your arc compatible tv plugs into arc compatible receiver. your gamestationbox plugs into the receiver.

not sure about your TV exactly... but your TV then has to be setting that ARC HDMI input as "receiver"... IE There is a menu option where you choose what you are connected to in the tv HDMI ports. you may have to also enable ARC or eARC or ARCaudio or something like that in the audio settings for the sound to propagate though the receiver.

if still not working perhaps the HDMI cable is no good. try another one. i have a bunch that just "went bad" and stop working...and you have to wiggle them to make them work again. too cheap to buy more.

my explainaition is a mess, but i hope it helps.

Arc really only does two useful things.

1.  Arc can be used to automatically switch your tv's settings to "game mode" when a game console is detected.
2.  Arc can be used to integrate a sound bar into your tv so the volume and powering on/off of the sound bar is done automatically as if they are the tv's speakers. 

My tv does #1 really well but #2 sometimes locks up my soundbar and I have to unplug it and plug it back in.
