What's the output of QT_LOGGING_RULES="*=false;org.kde.plasma.pulseaudio*=true" LANGUAGE=en kcmshell5 kcm_pulseaudio
Actually this might be better QT_LOGGING_RULES="org.kde.plasma.pulseaudio*=true" LANGUAGE=en kcmshell5 kcm_pulseaudio

Note that I have installed Qt Creator and Qt5 using official Qt installator. Not sure if it is related but maybe installator changed some KDE plugin's paths or something
OH, you are on Plasma 5.12.7! Right, so, I am almost certain what is happening is that Plasma 5.12 is in fact not compatible with Qt 5.12 because it is missing https://cgit.kde.org/plasma-pa.git/commit/?h=Plasma/5.14&id=c255ac792a0d6018ee19f98dfaccf90448a1a4ee
Yes, I'm on recent KDE Neon User Edition and seems that it is based on Plasma 5.12.7. So I have to just wait for some dist update?
Yeah I am not sure what you are on but it is not KDE neon user edition. User edition is using Plasma 5.14.5, about to become 5.15.0 even.
I'm definitely sure that I'm on User Edition: lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04.2 LTS Release: 18.04 Codename: bionic But I installed it long time ago when it was based on ubutnu 16.04 LTS. Then there was big Neon update which jump to 18.04 LTS. I'm always updating Neon using "sudo aptitude update && sudo aptitude dist-upgrade". So I thought that I'm always on recent KDE Plasma version. I'm suprised that recent is 5.14, weird
And if you look on my topic in KDE Neon forum, more people complaining about this issue and they also are on plasma 5.12. Do we all have disabled some repo?
Well, I am not disputing that it is broken. I am disputing that you are on user edition, you may be on user edition LTS. It's not really relevant though as in any event Plasma 5.12 is an LTS release and should be compatible with Qt 5.12, so my understanding is that the compatibility fix needs to be applied to plasma-pa 5.12.
Mmm, looking at KDE Neon download page and there is no more User LTS Edition, just normal User Edition. Seems that they abandoned it
Anyway... Should I report this somewhere else?
This explain everything: https://blog.neon.kde.org/index.php/2018/02/12/hiding-neon-lts-edition/ Indeed they are hidding User LTS Edition
So to sum up. Problem is on Neon User LTS Edition which is based on Plasma 5.12. I'll try today switch to non-LTS version because what I read non-LTS may be less buggy (it is tested more often and more accurately) and get new features sooner and this is what I'm looking for. Anyway as you said, Plasma 5.12 has to be fixed to be compatible with Qt 5.12

Thanks a lot!
