ARC connection - questions

[loendar]

I'm confused by all this - I have a Onyko receiver and Samsung TV (with external HDMI box) - on HDMI 4 on the box it shows ARC - so I plugged the cable from HDMI 4 on the TV into an HDMI in port on the receiver. I believe I've set everything to the proper things - Sound on TV set to Audio Out/Digital and Fire Stick set to Dolby, etc. but I can't figure out how to get the TV Sound out the surround sounds speakers. When I swap the video signal on TV to the fire stick that displays, but the audio is still from DirecTV. What am I doing wrong? If I missed info. you need please ask, I'm mentally shot.

I should mention that that the receiver apparently has an ARC HDMI out (which strikes me as odd) but no ARC listed on the other ports.

This is the receiver

Are you getting sound on the front speakers?

Are you getting sound on the front speakers?

Right now I am for the normal devices, but I get no sound from the fire stick. Other than the TV itself. I’m not sure how the audio from the fire stick is supposed to override the other audio which is all I hear. I’m thinking I need a new port on the receiver right now the cable is in bd/dvd

What if connecting the Fire stick to tv and tv to receiver via optical audio?

The receiver has an HDMI output that is labeled ARC because ARC uses extra wires inside HDMI cables to carry audio back from the TV to the receiver. Saves having to use an optical cable. Only one "input" on the TV is designed to work in reverse and both the TV and receiver both need to have ARC.
Did you turn on ARC in the TV menu. Turning on digital audio would probably be the optical audio out.
On the receiver you may have to select ARC as the audio connection for an input (such as TV or video 1) to access it.
