Neo A2 Lite Remote Volume buttons not adjusting receiver volume.

Hello,
I have a minix U9 with the latest firmware, that is connected to my Onkyo RZ-800 receiver, which is connected to my Epson HC 2150 receiver.
Everything works absolutely fantastic, including frame rate matching, HDR videos and audio passthrough, using latest Kodi Leia.

However, when I press the volume buttons on the Neo A2 lite remote, instead of adjusting the receiver volume, it adjusts the Android box volume, which is pointless.

Does anyone have any insight or suggestions of what should I try to fiddle with?

Thank you :)

edit: there are volume buttons on my projector remote, that indeed adjust the receiver volume just fine.

Hey & welcome to the forum :).

The volume buttons on the A2 Lite/A3 remotes are essentially hard coded to adjusting the volume levels on the U9-H itself, (alarm, notifications & media).

Regardless of having HDMI-CEC enabled on your different devices the volume buttons on the remote won't adjust the volume on your AVR or TV.

EDIT: Obviously I'm referring to the Android OS with the U9-H!

I can recall a post about this same issue on the old forums. Same question was asked (more or less), nobody got their A2/A3 volume buttons to work with anything else but Android itself.

If it's working with your TV & LibreELEC or CoreELEC, good, as they are different matters entirely to Android :). For the majority, however, with the stock OS the volume buttons will only adjust Android's volume & not any CEC linked devices.

I would be really very surprised if the A2 Lite, with the dongle installed in the Minix box, would produce any wifi function in any other equipment. But that's only the usual sceptical me I guess. I could accept an RF IR interference, in RF IR equipment or function (On and Off is RF IR in A2 Lite, Volume is not -I rechecked, just in case I could be getting crazy) but in wifi or with a dedicated dongle, as it is, that is a big mystery that I have trouble to understand or accept. Besides, how would that increase the volume in the other equipment and not in the Minix box all together? Makes no sense...o_O

If you install the A2 Lite dongle in a smart TV then it will obviously control the TV, I did this. In a receiver I never tried it though.

Exactamundo lol ;).
 
Thanks everyone for your prompt responses and valuable inputs!

So I installed the latest CoreELEC and the Neo A2 remote controls my receivers volume just fine!
But, if I use Kodi via the Android system, then the volume buttons control the Android volume.

I did some more digging and found that in CoreELEC, if I go to System settings - inputs - peripherals - "CEC adapter" shows up and if I configure it, the options seems to be HDMI "handshake" related, more than likely the reason behind the volume buttons working fine.
Whereas, within Kodi via Android, the Peripherals option was grayed out!

I did some google searching on how to install "CEC Adapter" but didn't really find anything.
There were some posts about using an SSH command to install libcec2 libcec3 but I dont know how to do that.

Would appreciate if there's any more insight you guys can provide!
Thank you!
 
The A2 remote volume buttons change the volume on my Samsung n950.

Great!
Are you running Kodi via Android (latest?) or do you have CoreELEC/Librelec installed?
If possible, would you please check to see what shows up under your Settings - System - Input Peripherals?

Thanks!!
 
If you have passtrough enabled you obviosly can't control any volume, not even on the box, either less anything else in the HDMI chain, doesn't make sense.

If you want to ajust the volume of the receiver use the receiver remote

Nothing beats faith. I was almost starting to believe it myself, they were so enthusiastic. :)

Seriously? You're likely getting confused between processing audio, which is not done with passthrough enabled, versus adjusting volume using HDMI link.
The whole purpose of cec/HDMI link is to control other devices.

For the record, you likely also missed my comment "So I installed the latest CoreELEC and the Neo A2 remote controls my receivers volume just fine!
But, if I use Kodi via the Android system, then the volume buttons control the Android volume.
"

Also, my projector remote has volume buttons that control my receivers volume just fine too, in addition to being able to navigate Kodi in Android, or coreelec. That's the beauty of cec.

Anyway, like I said, it's likely due to the cec adapter peripheral missing from my Kodi Android install that's causing the issue.
 
Seriously? ...

Seriously enough for us to still be all here writing comments about this subject.

Please be patient as people tend to fear what they don't understand (at least I do).

You mean to say that when on CoreELEC you can 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, without interfering with the volume of the CoreELEC system (because that is what CoreELEC is in reality, an OS for Kodi)?

Is this what you are saying?
 
I have never used the standard Android OS, but I can 100% guarantee that using librelec OS playing a movie on kodi if I use the volume buttons on the A2 remote then the volume on my Samsung n950 goes up and down and no volume adjusts on the minix box.

I suppose that you are talking about a soundbar, of course when you activate the volume in the remote with the dongle inserted in the Minix that will increase/decrease the sound coming out of the soundbar, that is its purpose, it doesn't matter which system you are using Android or LibreELEC however the hardware (physical electronic parts) used in the process of getting the current flow are the ones of the box, which has the remote connected to. The volume increases or decreases in the loudspeakers as they they get fed with more or less current from the box.

How can you confirm the remote is acting in the soundbar amplifier circuit directly?

That is why I was asking @tantanmay to check the movement of the volume knob in the receiver, that would really mean the remote would directly be controling the receiver.

So, due to my google search about this exact same problem I landed here. Tried to follow the discussion above and I can confirm: if I use Coreelec (latest version 9.0.1) if I adjust the volume through my A2 remote the volume of my Pioneer receiver changes. Now, I temporarly gone back to the minix neo u9 default latest firmware (fw008) and for some reason the volume adjustments do not adjust my receiver. So long story short: some funtionality in the kodi version on the Android firmware is missing / not implemented. Another thing I noticed, and may be related: if I change the audio source of my receiver to the input of the minix, nothing happens (my tv doesn’t automatically turns on and doesn’t go to the correct input). When using Coreelec this does happen and as soon as my change my receiver source, tv turns on and switches to the minix source.
Any help or solution or which sett8ngs to check would be much appreciated.

This discussion is getting old, and so am I. My problem about getting old is that I have trouble explaining what I can not understand. So I am still absolutely convinced that if the remote is connected to the Minix and the sound out of the receiver increases and decreases when you activate the volume keys of the Minix remote, there must be something wrong with your passthrough. If the remote is connected to the Minix and the sound out of the receiver doesn't change when you activate the Minix remote, then you passthrough is doing well, and you have to adjust the volume with the button or remote of the receiver.

Coreelec is an OS by itself, depending on the Minix hardware to work it's thing. When you are in Coreelec environment Android doesn't exist. Some are claiming that CEC from Coreelec would be capable to transform the wifi capabilities of the Minix remote into something the receivers could 'understand' and it would do this by bypassing those commands in the Minix hardware and activating them in the receiver. Sorry, this sounds... unbelieveable or maybe just too good to be true.

My previous question remains:

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?

The reason I ask this is because I can increase or decrease the sound for anything connected to my receiver with any remote commanding any device (because in reality I am not adjusting the sound in the receiver, but instead the output of the concerning device) connected to the receiver except:

The Minix sound from Kodi when passthrough is active.

But this one I can control with the receiver remote, but in this case the volume knob turns as the volume increases or decreases, as I am then in fact adjusting the sound in the receiver itself and not in the Minix.

I would be really astonished If the A2 Lite would by any means control the volume knob in my receiver when it is not connected to it by any physical or electronic means. But maybe my receiver is simply getting too old too.
 
Ok, so I get what you are trying to say I think. The situation is as follows when I am using Coreelec (passthrough enabled btw); I use the A2 remote and I can see the volume numbers on my AV Receiver front display appear and change. Does that answer your question?

p.s. Additional question: isn’t that one of the features of ARC?

Audio Return Channel allows the use of the audio channel through the same cable as the video channel, basically that is what allows your receiver to trade sound with the Minix or TV through a single HDMI cable with no need to use optical or regular audio cables. I never read anywhere that it allows the volume code to bypass the original device to command the second device (receiver).

The LED in the receiver changes as the sound output sent from the Minix changes, that helps you to find the optimal input to the receiver to avoid distortion, it doesn't mean the remote is commanding the receiver directly, how would it only increase the volume in the receiver without increasing the volume in the Minix all together?
