Well I was wrong. This new update TPM211EA_R.001.001.212.206 will solve some issues with Dolby Atmos when using an Apple TV. But then...it introduce some new ones. 😤

When playing a Dolby Digital 5.1 signal through the Apple TV you will notice that the audio signal for "front right", "front left" and "rear left" are played by the "front center" speaker. The audio signal for this center speaker is then replayed by the rear left speaker.

You can check this by installing the Apple TV app 'Surround Speaker Check'. It's free. Mine settings are 'Multichannel bypass' and eARC in AUTO.

When using a Dolby Atmos signal it seems to work fine.

Then there are some other issues when starting Dolby Vision videos. Someone else already created a topic about this: 55OLED806 -Dolby Vision software bug

It really seems that the software for the 806/856 is very buggy. There's still a lot of work to do. At the moment it is frustrating with using this TV. It's not a good start for Philips.

Here is what I did to minimise audio lag.
Set Audio out to Multichannel, roll down to audio out delay and set it to off.
You can only set audio delay to off if Multichannel option is selected.
Disable ALL unnecessary picture processing and AI options, use Filmmaker mode in SDR, HDR and Dolby Vision Dark/Bright.
Then go through ALL 3 options on your Apple TV as video outputs ( SDR, HDR, Vision) and do the wireless audio calibration. You will have to switch audio out to TV speakers when doing this calibration.
After you did all that switch back to SDR option on ATV and enable match dynamic range and frame rate.
Hope it helps.
Any problems, roll over to macrumours forum. :)

But with the Apple TV I don't have any issues regarding the setting Multichannel or Multichannel bypass. It's with some other devices like mine TV cable decoder.

The problem is that the audio is later then the video. The only way to extend the processing time of the video is to put the TV in Game mode (tip from Philips itself). But that's still not good enough.

But hey that's why there is a bypass function on every TV. This option should transmit the sound without any process. Let the Home Theater/Soundbar let do all the work of decoding and most of the time the automatic lip sync handshaking works fine.

But I have a strong feeling that the audio problems with this TV starts when you enable the bypass function.

And also on ATV the earc is still in beta. 🥴
You probably mean that eARC on this TV is still buggy.

Because eARC on the Apple TV is not in beta and works fine combined with other brands of TV's using eARC. It's definitely a Philips TV problem.

Yes eARC.
My bad :)
BTW do you have Easy Link enabled?

Well it seems that Philips is still investigating this audio problems. I've got some extra questions today from them. Those questions must help the specialists to solve the problem.

The new firmware TPM211EA_R001.001.233.005 still plays a DD5.1 out from the wrong speakers in certain situations (bypass, eARC). How could they have not fixed this issue.
They have created this bug with the previous firmware TPM211EA_R001.001.212.206.

And also the Dolby Vision bug still exists.

Here you can hear that the latest firmware TPM211EA_R001.001.233.005 introduce another audio problem. In the beginning there we're problems with playing Dolby Atmos trueHD. After they have fixed that audio problem they have introduced a new DD5.1 bug whereby in certain situations that audio is playing from the wrong speaker.

And now with this latest firmware they introduce another audio problem. You get sometimes a very annoying audio stuttering. The only solution I've found if you encounter this one is to remove the power cable from the TV to get a completely restart.

It is certainly not going in the right direction with these firmwares.

Instead of pulling the mains plug you can, hopefully, still reboot using Settings, Android, About and then Restart. If still in the 2021 TVs this should bring up the Philips logo and then Android restart…
… it’s a bit better than having to pull the plug. On my 2017 9002 I tend to do this every week or so as Android = Linux = a ‘C’ based operating systems with Apps that still seem to ‘back hole‘ memory, hence after a while there’s not enough free to continue without errors.

It would seem TVs don’t get enough testing as they now need and many bugs end up with customers to find - at least Philips on-line support is better than it was, so all issues need to be reported as we are all testers now :-(

No…there isn’t any option anymore to reboot the television. The only solution is the unplug the power. 🤔

Wanted to report that on my 806 HDMI ports #3 and #4 deliver Atmos signal via ARC (not eARC) with no bugs.

If you use the compressed version of Dolby Atmos then there will be no problem at all. It will work with any HDMI port. But this is nothing special. Dolby Atmos in compressed form worked with Philips TV's since 2018.

The problem appears when you use Dolby Atmos trueHD. In this case you need to enable the eARC function on the television (don't know why the default setting is off?) and change the digital output to "Multichannel - Bypass". Only in this case you will get trueHD. Because if you leave the setting in "Multichannel" the TV is transcoding the audio signal to a compressed form. Also if you use the built in apps you will get a compressed audio signal.
But with trueHD all the problems starts in certain situations. I've described them in detail on this thread and also to Philips.

Many people will not encounter this problem. They are using the built in apps, just the TV speaker,... In those cases Dolby Atmos is just a gimmick and really does not need a lossless signal. But if you have a home cinema/soundbar with rear speakers you definitely notice the difference in audio when using a blu-ray player, Apple TV,... And here appears certain problems.

The only thing we can do is to wait until Philips has an answer for those audio problems. But at the moment it is very silent at Philips.

fair enough.
AppleTV app Atmos from tv rear channels sounded fine. On plex also. Haven't checked yet Amazon and Netflix.

Just found this thread, and at least I’m glad that I’m not alone.

I have a brand new Philips 65” 4K OLED 650LED856 (I believe it’s just called an 856), a brand new Apple TV 4K (HDMI 1) and a brand new Sonos Arc (HDMI 2 eARC) with Sub and One SL’s as sorround speakers.

Sound is fantastic! Atmos signal detected in Sonos app and all is good.

Then I put the Apple TV to sleep, and when it wakes up again sound is gone! Just gone! No matter what I do - except turning eARC off and back on.

My solution (tested and it works for me): permanently turn off eARC and enjoy surround sound. And if I want to have Atmos sound, I’ll go in and turn on eARC on special occasions and watch movies from the built-in apps. Because Atoms on the Apple TV is bye-bye!

Is this an Android vs. Apple war that is being fought in the circuits of the TV??

Not impressed with Philips!

But thanks for all your insights.

@KristianDK Can you also create a case at Philips about your problem? Hopefully they will finally solves this issue if enough people will report them.

Yes, of course! I have raised the issue here at Philips Denmark and expect a phone call from a technician within a few days. I’m much more able to pinpoint the issue after having read this thread. Earlier I was going nuts, because I didn’t know what was going on.

I wish the interface on the internal Android system wasn’t so horrible compared to the Apple TV. Because I can play all titles with Dolby Atmos even with the eARC disabled. Unfortunately, that’s not possible on the Apple TV.

Here in Copenhagen, Philips Denmark suggested that the Apple TV should be connected to the HDMI eARC and the soundbar connected to another HDMI (all HDMI's on my 856 model support ARC, but only HDMI2 supports eARC). I was surprised by this suggestion, and it didn't solve my problem.

Status in my end is, that I cannot get Atmos on my Sones ARC, no matter what I do (switch eARC off and back to Autoomatic or even turn on/off power on all devices). Atmos on Sonos ARC via Apple TV 4K is completely broken! :-(

Well I maybe found settings to have eARC on Apple TV 4K

EasyLink : on
EasyLink remote : off
HDMI Ultra HD : Optimal (automatic game mode) for me, Apple TV is in HDMI 3 so not a HDMI 2.1 port
eARC : on
Multichannel : on (not passthrough)

With this, I have sound with the right spatialization
BUT I didn't find yet right settings for eARC multichannel passthrough, I can have sound but I still have wrong spatialization

Well this new firmware 001.001.233.012 didn't do anything.

With eARC in AUTO and digital output set as multichannel you can get a Dolby Atmos signal. Although it is in a compressed form and it seems that the auto lip sync is not working. On some devices the video is before the audio and you can't adjust this problem.

With eARC in AUTO and digital output set as multichannel bypass you get in principal a Dolby Atmos non compressed audio. With the previous firmware you where able to get a Dolby Atmos signal. But there was a problem with the Dolby Digital 5.1 audio. The audio was played through the wrong speakers.

Now they have solved that issues in a Philips way 🤬. It's no longer possible to get in this configuration a Dolby Atmos signal. The best you can get is a Dolby Digital 5.1. Strange...what does the bypass function in this televisions actually do?? It is certainly not bypassing the audio. Sometimes the audio is also stuttering.

Will write again to Philips...but it really seems they are NOT taking us seriously.

Did some more testing with the Xbox. Since the Xbox is using a compressed audio form. You can have a Dolby Atmos signal with eARC in Auto or even in OFF.

But it seems that the only way to get Dolby Atmos working is to set the digital output to Multichannel. If you change this to Multichannel Bypass the best you will get is Dolby Digital 5.1.

It seems that you can only get a Dolby Atmos signal by using a compressed form with Multichannel. You actually do not need eARC for this. You can switch it off.

Sadly some devices like the Apple TV don't use any compressed form. You will need eARC for them. But if you put with those devices the digital output to Multichannel Bypass to actually get a Dolby Atmos trueHD signal and a good working audio lip sync it isn't working as expected. The TV does only support at his best a DD5.1 signal in that situation.

I have Dolby Atmos TrueHD from my Xbox to my receiver connected with eARC. The TV is set to multichannel bypass. I tested it with a movie.
