Comment 4 for bug 1857392

Hm. I think these may be a symptom of an underlying problem (or problems) that is causing really weird bugs related to all kinds of things.

A few things that I noticed:
- I tried mapping 'previous track' to Ctrl + Alt + Left Arrow and 'next track' to Ctrl + Alt + Right Arrow which just simply didn't work in Ubuntu 20.04
- I mapped Ctrl + Alt + Down Arrow to 'play/pause' which worked in Ubuntu 20.04 so far, but in Ubuntu 19.10 it sometimes just stopped working
- Weirdly enough when you first try to map Ctrl + Alt + Down to a key it complains that it is already mapped to 'Move to workspace below' (which in the shortcut menu is shown to be bound by default to Super + Page Down), WTF
- Now a few seconds after sounds stop (e.g. when pausing a song in Spotify or even after system sounds) I see these exact messages logged to syslog. At the same time if Spotify is open it resumes playing the paused song, if it is not open, I get a popup with a "prohibition" symbol in it (https://en.wikipedia.org/wiki/No_symbol).

May I be damned but this all seems somehow related, although it looks like black magic from here.

I'm not going to say that it all just worked perfectly under Unity, but all this actually did work mostly fine in Ubuntu 16.04. Well, 'previous track' and 'next track' didn't always work but hey, at least the music didn't restart itself.
