Media keys stopped working for me after an update and then started working again suddenly. I checked the version and it's 1:184.108.40.206.gb45d2a6b-10. I don't know if the client was upgraded or a dependent package was upgraded.
The latest snap update 220.127.116.11.gf614956d-16 is not with media keys too on Kubuntu 19.04. It worked with the previous versions (but that couldn't play local files due to a bug). Spotify doesn't show up in the media player widget
Spotify 18.104.22.1680.g51b03ac3 . Running on Gentoo with Plasma desktop. All media players and browsers work flawlessly with media keys, not Spotify. Alternate media shortcuts via D-Bus commands is a nasty hack. Please address this.
Not working again for me either. I notice it works for awhile after a reboot but then I think plasmashell or pulseaudio crashed and had to be restarted and then the media keys stopped working again. Do the devs read these? I wonder if the code is relying on stale handles.
