RPI 4 Unable to initialize ws281x library.

Hello the community,

I have a config of hyperion who run fine on this setup:
Rpi2
Libreelec Leia last update
Config of hyperion with last hypercon

Now I want to change hardware to Rpi 4 4go

I've made the install of Leia then hyperion with last update (the same for rpi2)

I've made the copy of the json files to the folders.

But when I try to start hyperion with hypercon, I get the error:
Unable to initialize ws281x library.

Someone can help me please?

Sorry for my bad English....

Hello,

into the settings of libreelec the audio output is set on HDMI

Do I need to make some other stuff?

THX for replying

Edit 1: maybe add line to config.txt?
Edit 2: I've try to add "disable_audio_dither=1" in config.txt without effect...

I'm continuing my research....

In hyperion.config.json, I've change "type" : "ws281x" into "type" : "ws2812spi"

Now I've not anymore the problem with library

I've also enable "allow remote control by programs on other systems" cause I had kodicheck error who's ok for now....

Even if I've no more error messages, nothing works....

Ok I've made de transfert then reboot.

First led on red nothing else.

On hypercon, the result is:
ssh out: killall hyperiond 2>/dev/null
ssh out: /storage/.config/autostart.sh > /dev/null 2>&1 &
ssh out: cat /storage/logfiles/hyperion.log

Thx for continuing to help me !!!

Then, I don't know if I'm doing well...

Into Hypecon / hardware / type : Test (file)

Into Hypecon / hardware / Filename : /storage/output.txt

Into Hypecon / SSH : connect - stop - start wait 10s then stop

Nothing is created (no output.txt via scp)

I've created a file output.txt with 0777 permition, retry the test but noting is writen inside...

EDIT:
I've edited the files json and made the test!

like this:

You are amazing!

It works perfectly

Thx a lot

Edit: I will mark as solved after a few test
