When I start a VLC instance, I can control it with media keys (Fn, BT headphones, etc.). But if I then start a second VLC instance simultaneously, I cannot control that one with media keys. That's probably intended, it would usually be pretty annoying if both reacted. But if I then close the first VLC instance, nothing reacts to media keys. And sometimes I simply want to decide that from now on, media keys should control a different program.
PulseAudio has so crazy many features, surely I can somehow switch my media keys over to another program or instance, right? How do I do this? (Having a command line method for scripting would be nice as well.)
Setup info, in case it's relevant:
Manjaro 21.1.2
KDE 5.22.5
PulseAudio 15.0
VLC has some buttons bound, but most are set via KDE's system settings or just left default. Both have the exact same issue.
