eARC not working after Apple TV 17.5 update

The MU7000 is said to support ARC but not eARC.

That shouldn’t matter for the ARC/eARC functionality through Apple TV 4K (2nd generation or later), though. The Apple TV box would try to support either one, the ‘highest’ that is supported by the TV.

• If you can't set up HomePod or HomePod mini as the default speaker for Apple TV, make sure that your HomePod or HomePod mini and Apple TV are added to the same room in the Home app. Then try to set up your HomePod or HomePod mini as the default speaker for your Apple TV again. 
• You might have to turn on ARC, and/or HDMI-CEC (Anynet+ on Samsung) in the settings of your TV. Check your TV user guide for details. On my Samsung: Home﹥Settings﹥General﹥External Device Manager﹥Anynet+ (HDMI-CEC)﹥On Home﹥Settings﹥Sound﹥Sound Output﹥«Apple TV» Home﹥Settings﹥Sound﹥Expert Settings﹥HDMI eARC Mode﹥Auto How to use HDMI ARC on Samsung smart TV - Samsung Support
• Probably a good idea to verify that CEC is also (still) activated on Apple TV: Settings﹥Remotes and Devices﹥Control TVs and Receivers﹥On

Is this a compatibility issue?

It shouldn’t be. Not sure what’s up. At this time, I would suggest to contact an expert from the Apple Support staff for further assistance. Contact Apple for support and service (phone numbers) or start your support request online (chat/​email/​callback).

Same thing as happening to me as well. I have a Sony A80J OLED tv along with third generation 4K, Apple TV and second generation HomePods. I’ve had this set up for over a year now and it’s always worked. One day after updating the 17.5 is when the Earc stopped working audio still plays through the air HomePod while watching Apple TV but will not work on my other devices. This is definitely a software issue regarding 17.5.

I have exactly the same problem since tvOS 17.5 (including tvOS 17.5.1) with my Sony KD-43XH8505 TV and my tv 4K, and my stereo pair of HomePod minis. Everything has the up-to-date OS. All cables have been tested. All devices have been restarted. the eArc setting on tv has been toggled off & on many times.

It all worked perfectly before this update! The Sony TV sound was correctly routed down the eArc path back to the tv and then on to the paired HomePod minis.

Now the HomePod minis still play tv sound fine, but the Sony TV sound is nowhere to be heard.

This is a very frustrating bug as it was a struggle to get my partner to accept the HomePod minis in the lounge even when they worked perfectly. Now that they are not working properly and we have to resort to the TV speakers when playing TV and the HomePod speakers only when we are playing tv content, it is a source of contention again.

Come on, Apple. Get this bug fixed with urgency. Please.

eARC is not working after Apple 17.5 update.

What aspect is not working?

Do you use HomePod speakers [1]? If not, then the Apple TV box and its version system software doesn’t matter for eARC functionality.

eARC is for the connection between the TV and the audio system. What is your model Samsung TV and the introduction year for that model? What is the brand and model of your audio system?

CEC over eARC Made IT possible, that my Apple TV Turns my AvR and Beamer ON and OFF. Since 17.5.x only the Off Signal works. My Beamer No longer turna automaticly on. Please fix the Update @applesupport!

Has anybody figured out the issue? Before I was able to turn the eARC setting on my Apple TV 4K with 2 HomePod minis and could watch TV, listen through my ps5, etc. Now it’s only giving me the option for ARC and I can’t use my HomePod minis through any other hdmi source.

Same thing is also happening to my Sony tv in my bedroom. Also I have 2 HomePod minis hooked up to an Apple TV 3rd generation. Again Earc was working before the update and now it’s broken.

We have exactly the same problem with a Samsung TV. I do not understand how APPLE can release such updates that do not have software debugged.

I don't understand what made me switch to 17.5...

APPLE should sort things out with the employees responsible for this shoddy work. I have invested thousands of euros in APPLE products, but they are just overpriced things that have not been reliable for years and are certainly not at the cutting edge of technological development. There isn't a year when there aren't problems with something. I think I will end up with APPLE soon and switch to another brand.

It still works with my Sony X90K, Gen 2 HomePods and Gen 2 ATV 4K.

After a week of not working mine is all of a sudden working properly again. Still kinda strange this happened without any update fixing anything. Oh well!
