LED stays black at Alpha Version 9

[N1c093]

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

Bug report

After the upgrade to Alpha Version 9 my LED "ws2801" stays black.
The LED also stay black, if I set a color manually.

When I downgrade to Alpha 8 everything runs fine again.

Do you need more log files or somethin else?

Steps to reproduce

Upgrade to Alpha 9

What is expected?

LEDs should light up, for example the "Warm mood blobs" effect

What is actually happening?

Nothing, LED stays black

@N1c093 Could you Check, if there is a difference in behavior, if you disable smoothing?

[N1c093]

@Lord-Grey After I disabled smoothing the LEDs work as expected.

Are my settings wrong or is it a bug in Alpha 9? In Alpha 8 my smoothing settings works fine.

These were my settings in Alpha 8:

These are my settings in Alpha 9:

[Lord-Grey]

@N1c093 Thanks for reporting back.
In the latest release an additional smoothing methods was introduced. It might be that that change negatively impact the overall smoothing capabilities.

After switching off smoothing, it worked. Did you try turning smoothing on again? Does it work afterwards?
Could you try with Continous Output (Fortlaufende Ausgabe) enabled?

Plus Test not with Linear but the new method on?

I would like to see, if it is broken in general or if there are good or toxic config combinations,

Thanks for your support!

[N1c093]

@Lord-Grey

I did some tests today.

• Turning smoothing off and on again doesn't help.
• Enable "Continuous Output" works 👍
• Set the mode to "Dämpfung" only work with "Continuous Output" enabled. Btw. "Dämpfung" doesn't looks good for me, it's pretty slow and there are lots of lags.

In summary: The smoothing only works if I enable "Continuous Output"

I'm happy to help :)

[drinfernoo]

I've switched to alpha9 and back to alpha8 probably a dozen times in the past few months just to see if I could get it working, and finally found this issue.

I can confirm that setting "Continuous Output" makes alpha9 work with my WLED controller again!

EDIT: The issue I have with keeping "Continuous Output" on at all times is that Hyperion always has control over WLED, even when using "Signal Detection"... So if there is no signal, WLED doesn't revert back to manual control.

EDIT 2: Turning "Smoothing" off completely seems to make it work correctly... but without smoothing 😅

[Lord-Grey]

Can you re-test with alpha10 and report back please, if the issue is still present?

[N1c093]

Sadly the issue is still present in alpha10.
The smoothing only works with "Continuous Output" enabled.

[Lord-Grey]

@N1c093 Thanks for reporting back.
