            Bug ID: 467879
           Summary: Media player control keys break until system reboot
                    (play/pause/forward/back)
    Classification: Plasma
           Product: plasma-mediacenter
           Version: unspecified
          Platform: Debian unstable
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: MediaController
          Assignee: ksi...@gmail.com
          Reporter: aeyad3peij4ae...@mydomainnameisbiggerthanyours.com
  Target Milestone: ---

STEPS TO REPRODUCE

Here's how to reliably break the media keys (pause/play/forward/backward):

Start Audacious and play an audio stream.
    https://ice6.somafm.com/dronezone-128-aac

Look up the IP of the audio stream host and use it to null route.
    host ice6.somafm.com
        ice6.somafm.com has address 208.64.184.36

Block the IP of the stream.
    sudo ip route add blackhole 208.64.184.36/32

Wait for player buffer to flush and stream to stop playing.

Quit/kill player while it's waiting for the stream to restore.

Clear the null route.
    sudo ip route del 208.64.184.36/32

Start Audacious again and play the stream.

ctrl+alt+l to lock screen. Media controls are now missing and don't work.

Do this whole procedure a second time and media keys are now broken in KDE
proper.

OBSERVED RESULT

Media player control keys are now broken until system reboot. Restarting
sddm/kwin/x11 is not enough. Restarting dbus also didn't fix it. I'm not sure
what would fix this. It's outside my skill/knowledge area.

EXPECTED RESULT

Media player keys should not break.

SOFTWARE/OS VERSIONS

I am on KDE 5.27.2 on Debian Unstable, last full system upgrade on 20230317.

Operating System: Debian GNU/Linux 12
KDE Plasma Version: 5.27.2
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
Kernel Version: 6.1.0-6-amd64 (64-bit)
Graphics Platform: X11

This problem first started some time in the last year, maybe six months back,
but it could have been anywhere from 12-6 months that I think this bug was
first noticed. I first documented having the problem on 2022-09-15, but my
previous system upgrade was back on 2022-05-16, per my documentation.

ADDITIONAL INFORMATION

There is a reddit thread on what I think might be the same issue here:
https://www.reddit.com/r/kde/comments/sy8uuj/media_controls_randomly_stop_working/

This might be similar to Bug 418288.
