Issue with Volume Keys KDE

I'm having a very strange issue with my volume keys / volume knob. The keypresses from the knob are visible when running libinput but are ignored by kde and don't affect my system volume.
My audio setup involves easyeffects with pipewire. Adding in a seperate widget for volume control besides what is in the system tray doesn't work either. My keyboard comes builtin with both a windows and a mac mode for whatever reason and the volume keys appear to work on mac mode. Annoyingly the firmware sucks and messes with the function keys as well making them requiring the press of the fn key to work normally. I can bite the bullet and deal with that but I want to figure out why it doesn't work. In both keyboard modes the volume up and down keys are received but only in the mac mode do they work in kde.

Re: Issue with Volume Keys KDE

What keys are received? Post an output of such a libinput debug trace and compare them between modes. It really sounds like a different key gets sent between the modes. You can btw freely choose which keys to assign to the relevant action in system settings. (Assuming you're using and have present somewhere a plasma-pa based volume widget)

The split is where i toggle between modes. I am unable to do any form of rebind in mys system settings. It just ignores the volume knob and doesn't bind anything. Rebinding works when on mac mode which yet again has weird firmware behavior on the fn keys.

Re: Issue with Volume Keys KDE

Update, I found the cause. Not sure if this is a KDE thing, a keyboard thing or a mix of both. KDE recognizes part of the keyboard as a mouse for some reason and the device corresponding to that "mouse" got disabled. This for some god unknown reason made the volume knob and media keys dis-functional. This is probably a unique issue with my keyboard (Drunkdeer A75) but still very strange nonetheless.
