[SOLVED] Sound settings are reset after upgrading

Env
KDE Plasma 6
pipewire

Problem
After some related upgrading, the settings are reset.
e.g.
For HDMI audio ouput, it disabled manually,
and for Headphones, it is set to mode "Analog Stereo Ouput" instead of "Analog Stereo Duplex" manully.
After some upgrading about the audio system, the sound settings are reset, so that I have to set them manually again.
For arch linux upgrades frequently, it's better to keep the settings.

Create the file

sudo touch /etc/systemd/do-not-udevadm-trigger-on-update

Any side effects?
If not, why isn't it by default?

Side effect is that udev rules are not immediately applied, i.e. if you have a device that would need new information from udev, you'd have to actively replug the device or run udevadm trigger -c change yourself, it's not default because the systemd packager follows an upstream suggestion, that seemingly no other distribution implements in that way.

The topic  is somewhat controversial and I'm an advocate for not doing it, but there are pros and cons, IMO the cons far outweigh the benefits from doing the trigger.

@V1del
After some upgrades, the shortcuts for dolphin restores, and it needs to be deleted and created again.
