Hi All, Just a quick queston, i have come across a few albums on tidal that are dolby atmos. My A6 is connect to my Marantz AVR at the moment via RCA. For me to get Dolby Atmos to work correctly via tidal would i have to connect via HDMI?
if Audio pass-through was supported by the A6, then yes, you'd need to use the HDMI out to your AVR. AFAIK, that is not supported though (at least not yet).
Of course you would need to use the HDMI connection (RCAs are just plain stereo), albeit Dolbi Atmos is not (yet?) supported, neither as a pass-through, so no chance for now.
It's not so easy, than some people mentioned. Try playing a (local) PCM 7.1 file through HDMI out and you will see (on your AVR/AVP), that it results in a 5.1 coming out. The HDMI out from the DMP-A6 is limited to 5.1 (also seeing in Roon) and so also Dolby Atmos will not possible.
As I just added in another post, there could be an issue with the 2x unknown chips doing the DSD(?) decoding:
That’s not it. Dolby Atmos music only has two discrete track, the rest are mapped using the metadata against your speaker layout.
Where did you see that? As far as I know there is no distinction in the Dolby specifications standard when used for music or movies. It's just backward compatible to 5.1, 2.1 and 2.0
This question is asked several times in this forum. The specs from the DMP-6 state "HDMI out, Audio only, max. 5.1 channels". That means: No Dolby Atmos. These specs are there from the beginning. There are a lot of people in this forum wanting (or asking about) Dolby Atmos. The official comments in several threads from Eversolo have always been "Audio only, max 5.1 channels" and they never claimed it will be available in a future update. Yet people keep speculating that this maybe will supported in the future. I am not so sure of that. See also this thread: http://forum.zidoo.tv/index.php?threads/dmp-a6-tidal-atmos-via-hdmi.95678/
No, on a blu-ray Dolby Atmos use 7.1 with additional metadatas and with this you can get until 11.1.8. So you need at least 8 channels transferred through HDMI, which isn't possible with the DMP-A6. By the way: I'm so happy, that eversolo supports DSD5.1 (and this had become much more stable after some months) over HDMI. This is unique and it seems, that eversolo uses for this a special DOH chip for HDMI. For all the people, which can't live without Dolby Atoms: Buy a video streamer from zidoo, dune,... but then you'll never get the option to use native DSD over HDMI.
I mean... that's it: 5.1. nothing more than that, what are you complaining about?!?! There is no 7.1 mentioned anywhere!
You’re confused with movies, we’re talking about music. Dolby Atmos for music only has two discrete bed layer channel. Like other Atmos tracks, it provides the metadata for the mapping. Even then, 8 channels isn’t a requirement for Dolby Atmos on movies, that’s only with Dolby TrueHD based Atmos. The Dolby Digital Plus based Atmos only has 6 bed layer channels. You know why they use Dolby Digital Plus instead of Dolby TrueHD for streaming? Because you can’t stream lossless multi-channel yet. So how can you have Dolby Atmos for music on lossless 8 channel tracks via streaming? So please understand Dolby Atmos isn’t about the number of discrete channels. Or do you actually want to watch movies on the A6?
It doesn't matter if it is DD+ or TrueHD based Atmos there are no channels with Atmos (aside from LFE). Atmos is object based and the AVR decides where to send those objects based on the metadata it receives and the speakers connected to it. The only reason why streaming services use DD+ based Atmos is because of the bandwidth savings.
Do you have troubles reading? I know all that, didn’t you see what I said about metadata? We’re talking about bed layers. And I have to spell out about the bandwidth too? What is this, kiddies forum?
What bed layer? The bed layer is only used if the AVR doesn't support Atmos. Besides not being able to read, you don't understand what Atmos is or how it works.
Oh my Oh my God, the person I responded was talking about the A6's restricted capability of of only 5.1 is the reason A6 can't do Atmos, when the bed layer only has 2 discrete channels. The metadata is just a few kilobytes to map to your speakers. You don't even know what we're talking about and you dare to come and crap the thread. I remember you, you've been proven many times that you're talking out of your ass. Don't come talking like you know all when obviously you don't. Again, next time, READ, READ, READ.
This makes even less sense than the nonsense you posted before. I suggest you look at some Atmos tracks in mediainfo. It will clearly show how many channels and objects are used. That's rich coming from the king of talking out of his ass. That's all you do.
Yes, please do so yourself: Dolby Atmos Music Master Delivery Specification Mix and approval environment • All deliverables SHOULD be mixed, approved for home listening, and monitored in a room with atleast a 7.1.4-ch speaker layout. • All deliverables SHOULD also be monitored in a room with a 5.1.x speaker configuration. • It is recommended that the room configuration follows the best practices outlined in Dolby Atmos Music Room - best Practices for Music Room Configuration • All deliverables SHOULD also be monitored over headphones with the headphone render mode set to “Binaural”. Dolby Atmos Music master parameters • The number of PCM channels in the deliverable MUST NOT exceed 128. • The number of objects in the ADM BWF file MUST NOT exceed 118. • All deliverables MUST use 24-bit PCM resolution at a sampling rate of 48 kHz. • For projects created at 96 kHz, a DAMF (Dolby Atmos Master File) should be used if delivering for archiving. • If present, audio in the LFE channel of the deliverable SHOULD be band limited using a low pass filter with a cut off frequency of between 100 and 150 Hz. • All deliverables SHOULD have the Binaural Render Mode setting (Off, Near, Mid, Far) specified for each Bed Channel and Object. • Each track of an album SHOULD use the same Binaural Render Mode setting (Off, Near, Mid, Far) for each Bed Channel and Object. • All deliverables SHOULD use a 5.1 and 5.1.x downmix setting of “Direct Render”. • All deliverables SHOULD use a 5.1 to 2.0 downmix setting of “Lo/Ro”.

I treated myself to the Eversolo for Christmas. A great device. In the entire music world, Dolby Atmos and 3D sound are becoming more and more important every day. Dolby Atmos support for Amazon Music would be sensational. All the prerequisites are there. The only thing the Eversolo needs to learn is to output audio as a bitstream via HDMI. This doesn't require any additional hardware or computing power. The signal just needs to be passed through and forwarded to an AVR. This should be doable simply through software, whether it's DD+ or True HD. I have a lot of m4a files on my drive that I mixed in Atmos myself (my profession). They are played as 6ch files which is cool, but bitstream output would open a lot of possibilities. I hope this get's implementet in the near future with an firmware update, so we can enjoy the growing catalouge of 3d audio music.
This has already been discussed at length. As much as I would like it, I don’t believe Eversolo INTEND to implement it, even if it is possible. Also too this feature was never promoted as a feature so there is no obligation to deliver any such feature.
