Hi everyone!
I’ve just bought a mechanical keyboard (Trust GXT 866 Torix) which has a knob for volume control. When I try to turn up the volume, going up a notch results into an infinite spam of volume up inputs. The same thing happens if I decrease the volume. The only way to stop it is to press the knob, which also mutes the audio.
I searched online for similar issues but sadly I did not found anything.
Running evtest, this is what happens when the knob is rotated by one position:

This keeps spamming until I press the knob.
I tried the keyboard on windows (I have dual boot) and the knob works fine.
Lastly, I tried it on another laptop which runs Ubuntu 22.04 and the same problem happens.
I’m running Endeavouros with KDE.
