FireTV 3rd gen Cube - SoC T7 POP1-G (A311D2 variant)

Did you try having the Harmony remote learn the IR power command from the Fire remote? Maybe learning directly from the Cube’s IR blasters is giving it trouble. CEC should also be working to wakeup from shutdown and suspend, so that turning the television on itself would trigger a wakeup.

In CEC enable IR debug
CoreELEC:~ # echo 1 > /sys/class/remote0/amremote/debug_enable

Then press the power button on the harmony remote to see if the Cube recognizes the IR input. Press the button, check dmesg
CoreELEC:~ # dmesg

you’ll see something like this
[17685.207099] meson-ir fe084040.meson-remote: invalid custom:0xef10fe01

Above it’s identifying the received code correctly as 0xef10fe01.

I use USB hubs all the time, almost all work. You’ll definitely want a powered HUB for spinning platter HDDs.

For HUBs with Ethernet, many have a USB-C port for power injection

This was asked two weeks ago, but re: Fire OS capping DD+ Atmos to 5.1.2.

I’ve managed to fix that on the Fire OS side:

Again, this is was a Fire OS only limitation. CoreELEC already passes that format through.

Thank you very much. I wonder if that Ugreen one will work well with CoreELEC?

Yes, it will work with CE22.

I got FireCube 3, applied unlock, and installed CE-NO-22-rc1 from this thread - https://xdaforums.com/t/usb-emmc-bootable-os-coreelec-22-rc1-for-firetv-3nd-gen-cube-gazelle.4800618/.

  • I can install TinyPPI addon and edit skin shortcuts to invoke it show osd, right? is it integrated in any CE22 skins?

Yes, you can use any of the Tiny PPI advertised methods with this device and CoreELEC 22.

I’m using the keymap editor option to map to a remote button:

If you install jamal’s repository, he also has a fork of Arctic Fuse 3 with it integrated:

Thanks. I somehow got it to work and now have an activity on Harmony that wakes it up, but, unlike the original Fire Tv Remote that, with the same button is able to both wake up Coreelec and shut it down, the command I managed to teach Harmony only wakes it up. What would you say is the best option for shut down? Maybe in the Power Saving options set the Shutdown Function Timer to 15 minutes and let it shut down on its own?

The Fire remote is issuing two commands, a BT shutdown command (ignored when cube is powered off), and the IR poweron command (ignored by CE). The harmony remote is only issuing the IR power on command.

Add this remote2.conf, it’s only to make the IR poweron command (0xef10fb04) trigger shutdown in CE. It will be active after a CE reboot.

Place it in /storage/.config/remote2.conf Leave the other remote.conf file as is.
remote2.conf (1.5 KB)

Perfect now! Thank you for the patience.

Can someone tell me why I can’t play this 2 ch audio file in CoreELEC side? (It works perfectly fine on Apple TV Infuse).

Here is the file layout and details (remove spaces to view):
https:// filebin .net /eq5j6bqg7w8bo76t

File Name: Introduction by Director Alex Proyas.mkv
Container: MKV
Audio: 2-Channel

The video plays but I get no audio output. Any ideas on how to fix my Kodi audio settings for this?

Dear, I was able to install CoreELEC on the Cube 3 perfectly.

I have a question: the Fire Cube remote is paired correctly, but I’m unable to turn the Cube on using the remote, I can only turn it off. What could be the issue?

Folks, I sometimes wonder why Amazon didn’t include a USB 3.0 port and a Gigabit Ethernet port on the Fire Cube 3. It would be a perfect device.

I’m hearing the audio from your sample. This is my audio setup


you’re just now wondering about that when it was released > 4 years ago?

it comes down to being a Streaming device
A) most streaming services do not exceed 50Mbps bitrate and streaming focused engineering math says 100Mbps NIC is perfectly capable for Prime Video (and Netflix, and Disney+)
B) why spend more on a device you practically break even on building when all your revenue is in advertisements
C) USB 3.0 is tied to A+B, it’s simply not needed in a Streaming device.

I don’t know that it’s even primarily about money, USB3 and Gbit Ethernet consume more power. The Cube is an always on device, keeping power consumption low and temperature down is more important to Amazon than the >1% of users (I don’t think this is an exaggeration) that would benefit from USB3 and Gbit. By themselves these aren’t that much more, but you shave off where you can.

The Cube includes other components like a light sensor, who’s only purpose is to adjust the brightness of the LED bar depending on the room conditions. An IR receiver that is only used for IR learning which will never be used by most. A large aluminum block for the heatsink that is a bit overkill by streaming device standards. Despite Amazon’s reputation, their upper range devices (Cubes & Echos) are not skimping on hardware costs.

Powering the Cube on by remote is something you need to enable.

Hi, I have the same setup, but just noticed that under audio settings when playing the stream its defaulted to -60db and when moved up to -30 then I can hear it. Am I missing a default setting for this somewhere?

is it possible to send multiple commands on ON/OFF on the remote.. I have a projector that requires 2x off commands to turn off. or in general can i send off multiple commands, like power on, input select using the firecube remote?

Try the IR repetition option in FireOS

FireOS Settings > Equipment Control > Manage Equipment > TV > Infrared Options > Repetition > [Once | Twice | Three Times]

That may program the remote to send 2x IR presses.

0.0dB is the default for Volume, Volume amplification, and Downmix: Center Mix Level
