[BUG] bar1ch decay freezes when sound is turned off.

[ItsLiyua]

Desktop (please complete the following information):

• OS: Arch Linux
• Plasma: 5.25.3
• KDE Framework: 5.96.0

Describe the bug
After turning off the sound the bar1ch effect decays but after a few seconds the decay gets interrupted before all bars decayed fully. These little things that stay in the air for some time just kinda freeze in place. Once I start playing sound they start to move again.

Any error message shown in the console
Please execute the following commands in the console and upload the outputs.

git clone https://github.com/rbn42/panon.git
cd panon
git submodule update --init

You need to install plasma-sdk to get plasmoidviewer.

plasmoidviewer --applet ./plasmoid/
