Have you checked the TV audio/hdmi settings to see if there is anything that is adding some kind of cross processing to the Aura audio before it is sent down the arc?
Yep. There’s no “outside agency” impacting this. I may raise a support call with Humax…but it is just a niggly issue.
You may probably get more useful advice by talking to Sonos.
I am guessing that you have a recent model TV.
As a test, have you tried playing any of the various Dolby “test” videos on YouTube, directly from the TV YouTube app (so excluding the Aura) just to see how the Sonos reacts?
It might also be worth trying the same test files through the YouTube app on the Aura. If they all play correctly (without having to change anything) that will be a definite indication that the “video player” utilised by the Freeview operation either has a routing issue or possibly the codecs aren’t configured correctly.
YouTube Dolby atmos demos only output 2.0. They don’t demo atmos. I have read that from Dolby themselves you can download demos to a usb stick and play them from the stick.
What TV do you have?
LG SK8500
OK, same brand as mine (LG55cx5lb) and I have only very recently (as in yesterday :oops:) discovered a couple of things that may apply to yours because I believe they run basically the same operating system.
Despite being impressed with the image quality, I have been somewhat disappointed with the audio and thought that I had tried everything. But I have found that some setup options are not available unless you actually swap inputs (which is counterintuitive during initial setup).
So have a look at this to see if it helps.
Choose the hdmi input that is allocated to the Aura.
Then, using LG remote :-
Settings (cog)
All settings (3 dots)
Sound.
Additional settings
DTV audio setting to Auto.
Now this is the one that has made a massive difference for me.
Turn off eARC (otherwise the next option is greyed out).
HDMI input audio format.
Mine was Bitstream by default. I have changed to PCM and the audio is vastly improved (this option isn’t available when watching live/apps directly on the TV).
Then
Digital sound out to passthrough.
Make sure eARC is reactivated.
Then swap to Live TV on the LG.
Settings.
All settings.
Connection.
Make sure that Simplink is active because passthrough via eARC won’t function correctly if this is turned off (it should automatically activate when you select Sound out /ARC) .
Using these settings my audio via the TV speakers is vastly improved and when I turn on my AV system, the system now (finally!) correctly recognises that I want to use the ARC function and when I select TV (on the amp) and then either Live TV or an app (YouTube/iPlayer etc) the audio is correctly routed through my speakers (I couldn’t previously get any audio). My amp plays correctly Atmos from any source fed directly to it but doesn’t switch to Atmos when playing the YouTube test files but I suspect that’s because my amp is not eARC (but it may be that the YouTube videos aren’t actually Atmos at all?).
Apologies, I have only just noticed that you have already posted that YouTube Dolby tests are 2.0. That makes sense to the above post.
I have only previously tested using my Android media box and a couple of test files that are saved on the hdd.

I really do appreciate all the help but my LG only has Arc not eArc…so my options available are limited.
I only mention eARC because on my TV the extra options are greyed out until you deactivate it.
Do you have the options for bitstream/pcm?
And, on mine, the Digital sound out/passthrough isn’t obvious, it’s off screen so you need to scroll down down.

Again, options are limited. Digital sound out has only pcm or auto – there is no pass through option.
Do you have anything like this? (click on the pic for full size)
No, unfortunately I do not.
I contacted HUMAX about this and they want me to send my machine back and get a replacement!
I don’t think that there’s a fault here. But is there anyone out there using an AURA with a Sonos Beam (gen2) and getting Dolby Atmos output via BT Sport or maybe some other APP, e.g. Disney plus? If you are, which audio output setting are you using?
