Neo A2 Lite Remote Volume buttons not adjusting receiver volume.

If you go into Kodi settings (Leia), system settings, audio you’ll see on the very top “audio decoder”. Under Android/minix firmware the “audio output device” is greyed out. When using Coreelec and going into the exact same settings menu, you’ll see that you can select laudio output device” and change it. In my case there is a AVR option amongst others.
Now you are adamant that it is not changing the volume of the AVR, but it is doing the exact same thing if I either do it with the A2 remote or use my receivers remote...no no difference and in both I have access to the amount of audiosteps of my receiver, which are far more than that of the minix. That is, when using Coreelec.

As I said before, I am not easy to accept what I can not explain. This discussion is not leading any place apparently. It misses informed opinions to prove the remote volume code can be transfered from one device to another through the HDMI cable, bypassing automatically the function it was designed for in the first device. I can't see that written nowhere, and for me that doesn't make sense. If I would be able to change my sound with the Minix remote I would be looking for a passthrough malfunction. I am out, and assume my stubbornness. Thank you for coming back to this subject, so I got another chance to think over it once again.

I am not wishing you to be right only because it would just mean that your actual system, not allowing to change the sound in the receiver with the Minix remote, would not be working well, which I think is not the case, I think that now you got passthrough working well as it should.
 
Just added some screens fromthe difference in audio output device menu’s in Android and Coreelec.

But so just to get your thinkproces clear. You say: “When on Coreelec can you actually see your receiver volume knob phisically turn left or right as you press the A2 Lite volume buttons with the remote dongle inserted in the Minix box, or is it just an electronic process?”

My question would be: what if “the volume knob” on my receiver doesn’t move even when I use the receiver’s remote? If that is your prerequisite for the volume on the receiver being adjusted through a remote, I might be in a problem, because even the receiver’s own remote isn’t moving the volume knob, yet the sound does get louder (even my neighbours agree :) )
Now, maybe you’re having some elitist semantic discussion about ‘volume’ and ‘loudness’, in which case I don’t get it and don’t see the point as to how that would help in any way with OP’s initial question.
 
Screens aren't showing (EDIT now they are) however I would be sceptical about any changes made to the audio before it gets into the receiver compromising passthrough.

(Elitist semantic? Pal, this is not even my language, this is hard for me as it is, or would you prefer to discuss it in my language instead?)

A vontade, queres falar Portugues? Explica em Portugues se isso é mais facil.

Anyway, I just had to ask about you insisting on the fact that the volume knob of the receiver has to move for any volume/loudness change to be actually on the recever. My reply is that if my knob of my receiver (Pioneer VSX-528) does not move, ever. Also not when I use the remote of the receiver.
 
What you should have understood is that the knob question would be a simpler way to detect that the remote code couldn't reach your receiver to activate the volume there instead of the Minix. But since your receiver doesn't have that to guide you there is not much more I can add to what I already said.

(Good try, but you missed the accents in your Portuguese. That level won't be good enough for you to match me on an elitist discussion, and now I am convinced that my English is better than your translator engine anyway. Let's avoid messing things up any further.)

Born from Portuguese parents in Lisbon, lived my whole life in the Netherlands...Don't assume too much.
 
I am not assuming anything. You seem to be more worried about defiying me for some strange reason than debating the main thing discussed in this topic which is: Neo A2 Lite Remote Volume buttons not adjusting receiver volume.

I already told you my difficulties in accepting your opinion, yet you insist and reinforce that I should for some reason base my opinion in some scientific reasons that you also don't seem to have to support yours. Then you accuse me to be trying to get you into a semantics trap.

Your English is good. I am not going to defy you for a discussion in Dutch, why would you think that bragging about your Portuguese would set me down? What did that reply of yours bring to (what was the expression you used?)

"in which case I don’t get it and don’t see the point as to how that would help in any way with OP’s initial question."

Please note that I've been with you discussing the theme always! If you have any issues with your parents country this is probably not the time or the place.
 
I replied and you assumed and try to belittle it by starting about a 'translator engine'. The discussion is indeed what it is and everything else is not relevant.
But coming back to that you seem fast set on the fact that receiver control is impossible, while I (and others in this thread) are saying it isn't. Kodi has CEC control which allow you to:
Controle Kodi from the TV's remote control, automatically switch to the right TV input device, let the HTPC control what mode your audio receiver is on when the TV switches on, turn all devices off with one remote and set volume/mute of the receiver. (source: https://kodi.wiki/view/CEC)
But again, you are quite adament it isn't possible and pretty much imply people saying differently are imagining things?

So whoever lands on this page (as I did) after a Google search: if you run LibreElec or Coreelec on your minix u9-h, CEC control with the A2 remote is possible and it works. Under Android and minix firmware, CEC features are limited.
 
What you are assuming about CEC is that it is designed to do more that is is said to do in all written places about it. I was there, looking for an answer, in the Coreelec and LibreElec websites particularly.

And if you read carefully above, there are both opinions there as this subject is not cristal clear. For CEC to behave as you expect there would have to be a universal volume code implemented in all kinds of remotes that would be translated by CEC to the receiver. If Android, which is a complex OS can't perform this, why do you think any SO in a pen drive, having to be fully translated by the USB reading hardware in a machine would be capable to transmit the implemented remote code dedicated to that particular machine together with the audio information of the pen drive in that machine to a third party is something that is for me mind blowing.

It is getting to me quite obvious that I should by now rest may case here as others already did. I am sorry however that I am not being able to convince you that your system is good, as I think it is. That was my purpose when I decided to reply to you in first place, not achieved.

(Deixa de ser o D. Quixote a lutar contra moinhos de vento! ;))

I came back to your pictures and actually got a remark that you might wish to consider:

I can see that you are setting the Audio Decoder, however according to my records, that should get the digital compressed code from the media and decode it within the Kodi platform. I know not enough about Linux but I can see the Advanced Linux Sound Architecture (ALSA) is defaulted with some analog mention, that is also a bit fishy.

You should wish to have the digital coded audio passthrough flowing as is to get decoded to TrueHD at the receiver instead. In my humble opinion I reinforce that you should look at those passthrough priorities. It was weird that you could control the passthrough audio with the Minix remote, it just got less weird now that I got a better look at those settings.

I am sorry to be bothering you, but owning one of the best boxes in the field correctly updated you shouldn't be feeling this issue to be wrong with it. And also because, as you said, this discussion, apart from any of us to be right or wrong, can hopefully be used by others dropping by.

@CyberRider I'll try to respectfully educate you, one more time. Youre getting confused between a couple of things.
- To answer your question, YES, pressing volume buttons on A2 lite remote changes the volume of my receiver, while the dongle is connected to Minix.
- This function has nothing to do with passthrough settings, it's called HDMI CEC, which is not some latest and greatest tech, it's been there for years now.
- another example would be channel auto switch, or TV turning on by a source device turning on, auto input change on TV/receiver etc based on the active source etc.
- The volume knob's dont turn on receivers when volume is changed via a remote for decades now, unless manually turned.

In simple terms, the CEC functions let all HDMI connected devices, communicate with each other (NO IR, bluetooth, RF needed, all done via HDMI cables and CEC enabled devices) to adjust things like Auto resolution, auto frame rate handshake, volume control etc.
Another example, TV remote controlling the navigation for my FireStick, or the TV remote adjusting volume on my receiver, all happening since years!

Anyway, on the topic, pressing volume buttons on A2 remote perfectly adjusts my receiver volume, while running CoreElec or Libreelec, but DOES NOT when running stock firmware and that's what I and @schelling30 were trying to find a solution to.

Edited to add: Above is true with passthrough enabled or even disabled, as passthrough just decides which device does the audio processing, NOT which device controls the volume.
FYI, even my projector remote, can control the volume of my receiver just fine, whether the source is Minix or firestick or bluray player.
Point being, the capability is NOT built into the dongle (as you keep thinking) it's a standard for HDMI capable devices that have CEC functionality.

Lastly, I would suggest you refrain from comments like these (is why I stopped responding, but giving it another go to educate you, as I see from your subsequent posts that you want to genuinely help others)
Nothing beats faith. I was almost starting to believe it myself, they were so enthusiastic. :)
Seriously enough for us to still be all here writing comments about this subject.

Please don't spend your efforts on me. Since you have such knowledge and machines like ours, please feel free to help the ones in need as I was trying to do. As far as I know your apparently well informed theory is not supported by the information available elsewhere. I was not the only one here to doubt those capabilities but I was the one to write the most, that might have given you somehow the impression that I was the only one in need to be taught a lesson. But you are right about one main thing, among others, my old systems and ways are probably outdated, and that is exactly why I hope the clever and better informed ones come here and resolve questions from others, please don't you refrain. No doubt should I ever have any trouble with my Kodi passthrough or my CoreElec, you will be the first one I will ask.

And by the way I am sorry but I am obviously not able or enough informed to deal with your initial question, but when I replied to it by then I was just a simple member, and user, and quite irresponsible I must admit. Sorry if this eventually confuses you on what responsibilities I must admit nowadays, but the same as systems, also people and situations evolve in time.

Thank you very much for the great help so far.
