Hi,
I have just made a satisfying workaround for this. Indeed I extracted these 2 binaries from LE10:
/usr/bin/nano
and
/storage/.kodi/addons/virtual.system-tools/bin/mc-bin
copied them onto LE11 to my own bin directory /storage/bin/
as well as updated PATH env in .profile:
export PATH=/storage/bin:$PATH
and that's it. works without flicker. CHeers !!
Hi guys.
Does
HDMI audio Passthrough on RockPro64 work at all for all formats (TRUEHD, DTS, DTS-HD) ??
Have you got any issues with this ??
Hi,
DTS passthrough meets some issues on RK3399 RockPi 4 on LE 9.2.2-9.2.6
With enabled option of DTS passthrough the playback has to be stopped and started again couple time before it starts correctly playing DTS audio. This involves DTS and DTS-HD. TrueHD passhtrough does not work at all.
It looks like some initialization bug.
Dear Santa... I wish this to be solved before Christmas, thank you
It is hardware possible.
A LibreELEC developer just has to add a working patch for Rockchip devices, test it and build a new image.
Eg. for Allwinner devices these patches add audio passthrough - Allwinner: WIP audio passthrough · jernejsk/LibreELEC.tv@87cbddb · GitHub
So something similar with a few changes could work on Rockchip devices too.
But they first want to improve video playback I heard so audio passthough will likely take the back seat for another couple of months unless independent developers can do tests and create a patch.
Thanks for clarifying.
I see it was commited in July.. So nobody willing took care of it yet for Rockchip?
Not sure how the development goes - where can we put request in this case ?
Because no patch for it was added yet.
You can use the same patch as for Allwinner but need to modify it a bit to be compatible with Rockchip devices, which I don't know how to do.
The LE developers first want to add 10-bit, H265, VP9 video playback support for mainline LE before working on audio.
Allwinner: WIP audio passthrough · jernejsk/LibreELEC.tv@87cbddb · GitHub
So it might still take a few months unless someone can adapt jernejsk's kernel patch for Rockchip devices themselves or do it another way.
Well....in fact - 2160p@60Hz@10bit@H265is already working on RockPi4 moment as I write....how about moving forward in this 
??
For many different set top boxes: This particular setting that annoys numerous of LE users IS AVAILABLE but NOT IMPLEMENTED.
Why is this setting Available in so many LE machines when actually it is not working - what is more inconvenient - when this setting is NOT TESTED - then the noise may destroy home cinema speakers or at least shock the user.
Suggesting posting HDMI Passthrough reports in this Thread for developers and testers' convenience. How about gathering the devices and chipset down here and show if it's reasonable to disable the HDMI passthrough option in a release when it is not working ot not fully tested.
Why it is not being tested ??
In many boxes - especially this setting - is just abandoned for "students".....Why is that ??
As an example - my RK3399 RockPi4 box HDMI Passthrough is totally left aside while there where AndroidTV implementations already successfull. How can I find dev group for I could ask for HDMI Passthrough implementation in LibreElec ?? Please advice.
cheers,
Asia
LibreELEC with 4.19 kernel possible?
DTS-HD is working in my AndroidTV images for RockPi 4.
Try setting keep device alive to off and send low audio noise to off.
Hi.
In fact it does work on AndroidTV - and that is WHY still NOT YET IMPLEMENTED on RK3399 ?
LibreELEC doesn't support passthrough for Rockchip devices.
But what does it mean for future ?
1. no patch for LE is possible
2. it is a matter of patching "rk3399-rock-pi-4.dtb"
3. it is not hardware possible
Please comment - this functionality is really awaited for as it changes sound experience vastly nowadays.
Display MoreThese are reports from Rock64/RockPro64 but should be valid.
4K yes - HDR10 and HLG are played back with the correct EOTF flags (so trigger HDR modes on TVs) but HDR10 mastering and MaxCLL/FALL metadata isn't currently passed.
VOB seems to be OK. (Including interlaced content)
DD / DTS SPDIF-quality passthrough may work depending on your AVR. It may not be being sent fully correctly - but my AVR copes with it.
Dolby True HD/DTS HD (including Atmos and DTS:x) doesn't bitstream. Decoding the non-Atmos/DTS:x stuff to PCM 5.1/7.1 is an option and works OK.
Should also add that 1080i h.264 Live TV is deinterlaced OK, and 1080i25 Blu-Ray rips of European TV series play OK too.
Can you tell WHY it does not bitstream ?? I am guessing are there hardware or license issues...
Hi, has anyone also problem with Direct Passthrough of DTS, DTS-HD and TrueHD on RockPi 4 ver A in Kodi ??
I get only loud white noise or something...the same I get on Android TV images. I was able to transmit DTS-HD on Odroid C2 but now looking for How to exclude that it's even possible to get DTS-HD working on RockPi ??
Has anyone experience DTS-HD playback issues ????
What might the limitations might be for DTS-HD to work in Rock Pi 4 while it works on AMLogics ????
Hi all,
Build is fine on RockPi4 A except couple things here:
- DTS-HD passthrough does not work - I checked HDMI cables but it generates trash sound - how can I deal with it ??
- where is Moonlight and Chrome - I dont see it repos, why is it advertised in title ?? how can I install it ??
