Internet Radio with Multi-channel playback via HDMI

The new firmware v1.2.10 with the new iphone/ipad app still only shows 2ch when adding the link and playing the stream through HDMI. And it plays back without center channel still. So the Android app showing 6ch must work differently than iphone / ipad.

 

Hi everybody,
I have a similar issue to report.
White listening to Apple Music, the files (e.g. Hans Zimmer Live) that are played as multichannel through my AppleTV, my DMPXA6 renders same as stereo.
Thank you for your help.

 

Eversolo only promised multichannel from locally stored files. And only up to 5.1.

The Dolby Atmos files from Apple Music will not play through the Apple Music app on the DMP-A6.

The fact that a radio channel outputs multichannel via HDMI is nice but was never something Eversolo said would be possible.

 

This is a good design, IMO, as it appears to be independent of the source, like: do we have, no matter from where, 5.1 channels? then we route them to the HDMI no matter what.

 

From Dolby Atmos Casting Application Note:
https://professionalsupport.dolby.com/s/article/Dolby-Atmos-Casting-Application-Note?language=en_US

The Google Cast SDK is provided by the Google LLC company. It contains several libraries for different
platforms (Android, iOS, Web) and cast app types (sender, receiver). These libraries implement functionality
for interacting with Google Cast devices, as well as controlling a casting session and media playback.
The Google Cast SDK requires mandatory support of defined media codecs (FLAC, HE-AAC, L-AAC, MP3, Opus,
Vorbis, WAV, WebM). Additionally, there are selected media codecs defined that can be supported in a
passthrough mode. Support of these codecs is optional and requires an external decoder integrated in the
customer platform. The following Dolby audio formats are supported in the passthrough mode:
• Dolby Digital (AC-3)
• Dolby Digital Plus (E-AC-3, EC-3)
• Dolby Digital Plus with Dolby Atmos (E-AC-3, EC-3)

 

Isn't pass-through what it literally means? The stream is handed over to the final link in the chain, and possibly decoded there (in the A6).
And the A6 never claimed Atmos support.

 

Yes BUT.
Atmos is backward compatible to 2.0 and 2.1, but as far as I know, you need to support the above codecs to do so or you might need the Dolby Atmos Renderer to do that. Not sure ..

 

Indeed.
Atmos is "backward" compatible, but you need to decode the stream in order to know where to map the non-existing phisycal speakers; like in the simplified example: the system does not detect side speakers? then the L&R side go to the L&R front.

 

Yep - Eversolo would probably need to add this:

and possibly the DTS:X equivalent

 

Don't forget there is a license to pay for Atmos... Is there a lot (and I mean A LOT) of Atmos music out there? I find it hard to believe, as just speaking of 5.1 the portfolio is not that big, so...
But I'm happy to be discredited, of course.

 

it's growing daily..
I have no idea how much is there though

Bitstreaming the original Atmos signal over HDMI to an AVR is all that's needed here (whether or not this would still requires a license I don't know). The AVR would handle any Atmos decoding (that's already one of their main functions anyway) and having a 2-channel device like the A6 decode Atmos doesn't make much sense.
