Yes it is.

It was tricky the reboot, but I manage to workout.

Very thanks team ;-)

Hello again.

I've read that is possible to flash directly on Minix memory.
I'm making this try with CoreELEC, mainly because of performance. My U9 is a bit slow and I believe with CoreELEC will run like Nvidea Shield TV ;-)

My big question..... is it possible to roll back the box to original state?
This means having the original Marshmallow Android.

Best to try it initially on your Micro SD & see what you think. An installation on a Micro SD card is a good option for the average user & there's really not a massive gain in system speed/responsiveness using the eMMC over a Micro SD.

If you still wish to continue the easiest way is to simply SSH into the CoreELEC you've already created on your removable media & use the ceemmc command ( https://discourse.coreelec.org/t/how-to-use-the-team-coreelec-ceemmc-tool/7630 ) which will transfer your existing CoreELEC install & settings directly to the eMMC.
 
Thanks guys for your precious answers, you are awesome!

I've read somewhere on the forum that is 10x faster the micro SD.

I've a micro SD of 64GB, red from Kingston wich reads 90MB/s and writes 80MB/s.

If I'm not wrong... normally eMMC is around 250MB/s, so should be visible the performance improvement.

With marshmallow on minix... the kodi is slow. So I would like to try CoreELEC before jump to another investment.... the shield tv pro 2019 ;-)

Hello multimedia enthusiasts,

After using CoreELECT for a week, I just can say that...... is GREAT.

Some feedback of my experience:
- on my minix with CoreELECT on Micro SD, I Just power it from IR and it jumps to CoreELECT, no tricky thing on power button+power conector is needed;
- minix takes 2 a 3 minutes to boot up;
- AEON MQ8 skin is toooooo slooooow;
- on default skin, it works great, but with a slight delay;
- it perform acceptable on films 4K with atmos (50GB);
- on Yatse, some times fail the connection and I've to reboot using remote control;
- on Yatse, and the images loading are slow;
- all services works, as expected.

Sooo, being said... it seems that I will jumpt to the next step, CoreELECT installed on eMMC!!!!

Can someone feedback if the performance will increase, like no freeze or slow performace with 50GB films or using Yatse?

Can someone, who has the CoreELECT installed on eMMC, feedback about performane, and if possible intall the skin AEON MQ, and feedback?

thanks in advance

I repeat, it is not the sound that matters, but the video codecs! Specifically, under Minix Coreelec, it is unable to play certain videos with hardware acceleration. I was looking for a solution to this, but then it does not exist! :cry: During some videos, you need to turn off h264 acceleration and solve playback with raw CPU power!

Hi, I have a similar problem like user Dolphine. I would like to passthrough DTS sound via a Panasonic TV with HDMI-eARC to my Sonos Arc soundbar. The soundbar can decode DTS bitstream. Works fine with movies on Blurays. But when I stream movies with a DTS soundtrack from my NAS with Kodi, the soundbar only outputs stereo sound. In this case, multi-channel sound is only played if the option Enable Dolby Digital (AC3) Transcoding in Kodi audio settings is activated. DTS is converted to DD 5.1 then. Passthrough of Dolby Atmos and Dolby Digital sound, on the other hand, works without any problems.

Does anyone have a similar setup and knows how to solve the problem?

Just having the facility to handle e-ARC doesn't mean DTS will automatically be supported.

My 4K model Panasonic TV, for example, doesn't support DTS passthrough or DTS playback through the TV's somewhat basic built in media player or any of the TV's native apps, period. It does, however, support all Dolby formats, including Atmos, & including full Dolby passthrough. (Not that I rely on my Panny TV for any passthrough duties myself as I passthrough directly from any given device straight to an AVR instead.)

Many Panasonic TV models (& other brands too) just don't support DTS passthrough, or support DTS playback with the TV or through apps on the TV itself. (Like many, it's why I have a separate AVR & separate playback devices such as the U1, U9-H, U22 with CoreELEC, or inevitably the NVIDIA Shields, the Beelinks, the Xiaomis, to name but a few, because of certain restrictions elsewhere in the chain.)

There are very few devices/systems available that can do it all!!! Obviously any that can are going to cost due to the extra implementation & the inevitable licensing fees required to support all possible standards.

So, double check if your TV model is also similarly restricted in the first instance before you start all sorts of unnecessary procedures or potential workarounds.

I don't claim to know anything about Sonos as I've never owned their kit but if you can get a direct connection to the Sonos without relying on the TV to do the passthrough, you'd have a far greater chance of success. (From what I understand from previous users commenting on using Sonos kit, there are also some restrictions with how everything can be connected so you may just have to take it as it is, or (yikes) consider some different kit altogether.)
 
Thank you ArcticWolf for your helpfulness. In fact, Panasonic no longer supports the DTS sound format in newer TV models. Nevertheless, my TV of the 2021 JZW1000 series can passthrough the DTS bitstream signal from my Panasonic Bluray player and HD recorder to the Sonos soundbar. The same applies when a film on my NAS is played from the Bluray player by the built-in DLNA client. However, it does not work reliably. If the soundbar only outputs stereo sound again, it helps to briefly switch the AV input or switch eARC off and on again.

Wit Kodi running as an Android app on the Minix Neo U9-H, my soundbar was also able to play DTS sound more or less reliably. But I haven't been able to do that with Coreelec 9.2.8 so far.

Unfortunately, the Sonos ARC soundbar only has one HDMI input. The TV is therefore the control center for transmitting the sound from the playback devices to the soundbar.

As you have already pointed out, it is not worth investing more time in this probably unsolvable problem. I can live with DTS sound transcoded by Coreelec to Dolby Digital 5.1. And for films with a resolution of up to 1080p, I can also use the DLNA client from the Bluray player.

No worries :).

Which Sonos do you actually own? (If memory serves from a previous user having similar issues then the original gen 1 only supports ARC & not e-ARC.) All devices in the chain must support e-ARC or it just wouldn't matter what capability your TV has as it will default to ARC instead.

The newer gen 2 Sonos Beam has e-ARC if that's what you own?

If your Panasonic TV is also similarly restricted & simply cannot passthrough any DTS audio, how do you know that the TV is bitstreaming DTS audio from your Blu-ray player or your HD recorder via the TV & through to the Sonos?

Are you absolutely certain that the Blu-ray player or HD recorder aren't first decoding the audio themselves & it's arriving at the Sonos as pre-decoded 5.1 PCM?

Regardless of the media source or the network protocol a device is using to stream the data , (i.e. your NAS & DLNA), if it's actually being played back on the Blu-ray player & it definitely has DTS audio but the sound is still coming passing through your TV that doesn't support DTS in any form, then in all likelihood your Blu-ray player is actually handling all of the decoding itself.
 
My Sonos speaker setup consists of the Soundbar ARC, a Sub and two Play One rear speakers.

A few months ago, Sonos activated DTS support on the ARC with a firmware upgrade. However, the high-resolution formats DTS-HD Master Audio and DTS:X are still not supported. When the ARC is playing a DTS audio track from a Bluray, the Sonos Controller app will indicate this. For the Bluray player, the HDMI output signal for DTS is set to Bitstream.

The films with a DTS soundtrack on my NAS are encoded with H264. The TV's own DLNA client cannot play the sound format, but the client from the approximately 8-year-old Bluray player can handle it. It is also strange that Kodi 18.9 on Android on the Minix Neo U9-H seems to output DTS as bitstream, but with Coreelec this is no longer possible. Multi-channel sound is only output if the Enable Dolby Digital (AC3) Transcoding option is activated. Interestingly, Coreelec has no problems with the Dolby formats and even Atmos is looped through to the soundbar. Which was not possible with Kodi on Android.

I have the same stupid question as Sandro7: which release of CoreELEC I should download for s912 (MINIX NEO U9-H)?
Trouble is, i'm so stupid, i don't understand the answer given :-( I can't find the path shown in the images and i keep going round in ever increasing circles.

Is CoreELEC-Amlogic.arm-9.2.8-Generic.img.gz the file i need to download? Or CoreELEC-Amlogic-ng.arm-9.2.8.tar? Or both? Anything else?

For a New Installation: CoreELEC-Amlogic.arm-9.2.8-Generic.img.gz
For an Update: CoreELEC-Amlogic.arm-9.2.8.tar
 
Many thanks. Earlier I finally found and downloaded the CoreELEC-Amlogic.arm-9.2.8-Generic.img.gz and CoreELEC-Amlogic.arm-9.2.8.tar.

When i unzipped the latter, i found the required gxm_q200_2g_minix_neo_u9.dtb file in \CoreELEC-Amlogic.arm-9.2.8\3rdparty\bootloader\device_trees.

So i finally thought i'd cracked it, but when i created a bootable USB drive in Rufus i could no longer get windows to recognise the drive. So i could not add gxm_q200_2g_minix_neo_u9.dtb (now renamed dtb.img) to the USB root drive. In fact i seem to have "bricked" my usb drive. I did this procedure before (many years ago - with a micro sd card) but don't recall this problem cropping up.

Sometimes the drive letter is not assigned for reasons unbeknown, check in Windows Disk Management if the USB drive is there and assign a letter to it if need be.

I always wanted to try CoreElec and the tutorial pushed me to try. Very easy to follow and have it running. Now what to do with it :) I'm not a kodi user but thought I'd try and get the Netflix running but got this error...approximately :) dependency on xbmc.python version 3.0.0 could not be satisfied
The Netflix I tried to install was from
