Apple TV 4K 3rd generation eARC sound issues, no problems with Apple TV 4K 2nd generation

Same issue. 2nd Gen works and 3rd Gen does not.

I gave up.

I got it to work for a short time, but not consistently.

There is a device that is an eARC splitter that worked for a few minutes. It was like a generic HDFury.

I tried Peacock for an episode in Season 3. It played perfectly in 5.1. I checked for the HMDI settings but didn't see any option for auto only to change the output 4K which I had. But after playing with some of the sound setting in the TV. Guess what? My original issue with no sound on HULU returned. Seems that LG G2 TV, eArc connection, Sonos ARC and Apple TV have a complicated problem to solve.

I will be working to resolve the sound issue again.

Wanted to provide an update. My only issue is that at random times, usually after an hour or so of viewing, my sound bar loses sound and it only comes through the TV. I’ll restart my TV and it works again.

otherwise I’ve had no other issues and it’s been working great.

Sorry but that's ridiculous. 3ft wouldn't even reach from the TV hdmi port through the flush mount cable holding slot on the back of the set down to the sound bar mounted the suggested 1ft below the set on the wall. That alone measures 3ft 7 inches not even taking any safe diameter bends in the cable into consideration.

Yes, you are correct about the article as I fully read it after I posted it HOWEVER simply search for the same question regarding eARC cable length and you will see that "pushing it" with a passive cable is when one exceeds 25' for eARC. I'd like to see anything that says 6' is "pushing it" WRT eARC. That would eliminate 90% of installs. That plus most every comment about this question on any of the major AV Forums say that using simple Amazon Basics high speed cables are fine for "normal" length eARC cable runs. All using these cables: https://www.monoprice.com/product?p_id=31231

In any case my setup is simple. 1 x 6' cable to SONOS 10" below the TV on wall from eARC HDMI port and 3 x 10' cables 1 each to Xfinity DVR, Apple TV box, & PS4. All 4 cables run down the 4 built in flush mount cable tracks on the back of the TV into a hole in the wall then down 2 feet into the back of the console below it. The cables have to run in the provided "tracks" or the set won't mount 99% flush to the wall "like a picture frame."

Have it your way snaking 6 footer cables and all, that’s a given. However, you do have a solution that’s rated excellent by over 11,000 Amazon users. That’s 11,000 users less posting to this discussion, in case you missed the point 😁. All the best 👋

I'm 54 and I notice a massive difference with Dolby Atmos with e-arc enabled and disabled. I guess i just like to get the best from the products I've bought even if the difference is little - this is definitely a bug in the Apple TV so it's frustrating they havent fixed.

Yeah hard for me to believe it’s an issue with the Arc.

Apple hasn’t even acknowledged this as an issue. That’s Apple support for you. If we don’t think it exists, it doesn’t.

That’s so annoying :(( I do hope it gets fixed as Apple TV is such a nice platform compared to my tvs native apps

Same here… atv 128 with lg c2 and sonos arc + sub 3 + era 100…. 5.1 problems … atmos and stereo work well but multiple problems with 5.1

youre right. I called this morning and they said they were not aware of it too…

17.2 doesn’t seem to fix the problem… this issue is very very frustrating!!

I’m using my $25 Roku 4K stick with Atmos support in the meantime. If Apple doesn’t fix it I’ll be sharing my experience with everyone in the tech biz I know.

Disabling eArc disables other features for other devices connected to the TV mainly control of power for all other devices like soundbar and cable box.
