[SOLVED] Audio device not set as "master channel" automatically

Hi! I'm running KDE installed with the "plasma-desktop" package. I've done the necessary tweaks to make bluetooth and audio work, and it's indeed working. My only problem is that when I connect my bluetooth headphone, although it instantly starts working, I've got to manually select it as the "master channel" in KDE in order to control its volume with the keyboard's "increase/decrease volume" shortcuts. Does anybody know how to make KDE do this automatically?
Just making it clear, the headphone DOES reproduce sound when I connect it with no additional configuration, I just can't control its volume with the keyboard. In order to do it, I've gotta right-click the kmix volume system tray icon, go to "select master channel", and select my headphone.

edit: when I connect my headphone and use the keyboard shortcuts, I change the notebook speaker volume, because it's set as master channel by default

Thanks for taking the time to read it

Hi! If you're having the same problem as me, I solved it by ditching pulseaudio (uninstall it), installing pipewire and pipewire-pulse and setting wireplumber as pipewire's  session manager. Reboot your computer after all

For prosperity pulse can do that as well but it does so with an optional module module-switch-on-connect which you can add to your /etc/pulse/default.pa
