only 1 led working

Hi,

what exactly do you mean with "rebuilt Hyperion"?

Did you rebuild the software or your hardware setup?

Was it working before?

Is the single led fully working and controllable with hyperion?

Best regards

you need root rights for Hyperion.NG to use the PWM controller.

PWM is also used by sounddriver so deactivate the audio in config.txt

dtparam=audio=off

(or remove the # in code line )

If you really just did a fresh install and changed nothing on your hardware setup

then i guess you somehow misconfigured Hyperion this time.

Like Ambient_theater77 said check if dtparam=audio=off is set in the config.txt and be sure

that you selected the correct DMA channel, PWM channel and GPIO
Does the log shows any errors?

Faulty LEDs?

Strange...

It's unlikely, but it doesn't hurt to test: try a different GPIO.

GPIO 17 is not a PWM pin. Try GPIO 19

What happens if you disconnect the data line? Does the white light goes off?

I don't think that the update is causing your problem but nevertheless you can download earlier versions on the github page:

https://github.com/hyperion-project/hyperion.ng/releases/tag/XXX

Just replace XXX with with your desired version (for example 2.0.15)

Would you please show me all your Hyperion settings? Maybe i find where the problem is.
