Can't seem to get volume/brightness osd [Bug]

[xendak]

Describe the bug I'm able to interact with the sliders from control-center, but the hotkeys to change volume/brightness don't really show up, instead i get an error message, as shown below in the screenshot tag.

via control panel, this is what i get, volume is "empty" though it works fine if i try to raise/lower/mute etc Control Panel

Expected behavior I'd assume they work like inside the control panel

Screenshots

Distro (please complete the following information): Arch Linux

Additional context i tried setting the value "manually" to see if the default was somehow on pamixer --get-volume, couldn't get it working anyways..
