Vero 4K - Atmos, Passthrough not working

Hi all, I’ve had am Vero 4K for a while now, many years of good service. I’ve recently had to change my AV Receiver after the old one blew up, switched to a Denon from a Marantz. Since the change I notice that all my Atmos files now show 5.1 tags (instead of Atmos), and during playback they show as PCM / Multi-Channel In and not Atmos at the Receiver end. My Denon supports all the formats, and is setup with an atmos-supported front heights speaker config.

I’ve had a read through of similar previous issues and the docs, so I’ve made sure I have “sync playback to display” off, “passthrough” on with all the various formats ticked, and I use a 7.1 speaker setup.

Logs from a session where I play the “amaze” atmos trailer file - https://paste.osmc.tv/cupisuniyi

I notice that there’s a lot of noise in here about a “default” output device being selected. In the UI, I can see two entries in Audio Output Device:

Default (AML-MESONAUDIO: HDMI, S/PDIF & analogue)
AML-MESONAUDIO HDMI

I have the 2nd one selected, and the same device selected in “Passthrough output device”. I can’t see why the default device is being used when I’ve explicitly selected the other one? Could be a red herring of course.

Many thanks in advance for any help,

Andy

Did you restore these settings from another device?
You could stop Kodi, delete guisettings.xml and try configuring again to see if that helps

Hi Sam, thanks for the reply.

No, the settings have only ever been on this device, all setup manually via the gui.

I deleted guisettings, things went back to defaults but after setting the audio options up again things remain the same unfortunately.

I have a Denon AVR 8500 and play atmos files perfectly well. If there is a configuration file I could share with you I am happy to do so, just might need a pointer as to how to do it.

See pictures for my settings on vero 4k+/kodi and this is connected to avr x4500h and this plays atmos as atmos.



I think the issue may be with how you have the Denon configured and how it is decoding the incoming audio stream.
Lots of chatter about this on newer Denons:

I’ve got a 4 year old AVC-X3700H, and don’t have these issues.

just wondering if this might help, my Marantz has a very quirky approach to enabling Atmos.

Some interesting ideas here, but I don’t think they apply in this case.

The Vero looks to be unwilling to send any audio format other than PCM / Multichannel to the receiver. Because the receiver isn’t receiving audio in Atmos format, just Multichannel In, it never activates any Atmos handling behaviour at all. I have passthrough on, but it doesn’t actually passthrough properly for whatever reason.

I have a 7.1 setup, and as such the amp doesn’t present me with any virtualisation options (because I have all the real speakers for an atmos setup, no need to virtualise anything).

@mtv in your “Audio output device” options above - do you have two options? One being labelled “default”?

OK, many apologies but it’s started to work. I switched out the hdmi cable for a fresh one. Maybe when the old amp went bang it did some damage along the way, I’m not sure. Or it could be an obscure cable / amp issue that wasn’t there with the older Marantz. Many thanks for all the ideas!

Yes i have the 2 options.

Glad to hear this, sorry to hear about the issue with the other AVR…
