Unable to initialize ws281x library. on Raspberry 4

[khauser]

• I confirm that this is an issue rather than a question.

Bug report

I can't get my ws2812B strip running:

pi@raspberrypi:~/hyperion/build $ bin/hyperiond
[hyperiond LEDDEVICE] <INFO> LedDevice 'ws281x' found.
[hyperiond LEDDEVICE] <DEBUG> <LedDeviceWS281x.cpp:60:init()> ws281x strip type : 1050624
[hyperiond ComponentRegister] <DEBUG> <ComponentRegister.cpp:36:setNewComponentState()> Smoothing: enabled
[hyperiond LEDDEVICE] <ERROR> Device disabled, device 'ws281x' signals error: 'Unable to initialize ws281x library.'

Steps to reproduce

I just installed via wget -qO- https://raw.githubusercontent.com/hyperion-project/hyperion.ng/master/bin/compile.sh | sh.
Then I started in the build folder: sudo bin/hyperiond (so not like #641)

With https://github.com/jgarff/rpi_ws281x I had working examples.

What is expected?

LEDs shine all the time

What is actually happening?

No LED is shining and there's an error

Manually update your ws281x, the important part is this file here:
https://github.com/jgarff/rpi_ws281x/blob/master/rpihw.c
There is a RPi4 v1.1 and v1.2, you likely have the v1.2 like I did.

did it worked? could you solve your problem?

Same here, tried what @Zenairo wrote and still get [hyperiond LEDDEVICE] <ERROR> Device disabled, device 'ws281x' signals error: 'Unable to initialize ws281x library.' on Pi 4b 4GB v1.2

The old hyperion works fine with the same settings on the same pi.

I have now SK9822 in place, which also runs fine. Thanks for all of your great work!
