Hi,
today I installed KDE Neon (5.21).

While I installed everything i listened to music via Spotify. Everything worked fine.
Now i noticed that the hotkeys for lowering/highering the volume started to mute it. The volume is still changed, but the application gets muted, so i have to unmute it myself every time.

The hotkeys were already set after the install. It worked fine so I didn't change anything.

Does anybody know how to fix it?
