polybar crashes and dumps core when interacting with module/pulseaudio after `pulseaudio -k`
Possibly related to #2170 since it's window manager agnostic, and has the word pulse throughout the trace. Also #1580
polybar crash scenario primed when pulseaudio user daemon is restarted
Today I had a fuzzy audio issue with pulseaudio. I use an aggregate device via the paprefs program, which lets you set up a simultaneous output interface. Note that I also have pavucontrol running, which is a systray icon for controlling pulseaudio.
In order to clear it up, I ran pulseaudio -k as my normal user, which kills the running daemon and allows it to restart. This fixed my audio issue, but it broke polybar in that when I now interact with polybar's volume slider, it crashes and coredumps. The first time it happened during my i3 session, it completely froze my entire machine for a good 30-40 seconds (audio kept playing, so it was strange), and there were some graphical glitches - as for user input during the issue, no mouse cursor control, no numlock toggle, couldn't even Ctrl-Alt-F{1..7}, Ctrl-Alt-Del, or sysrq-trigger (LAlt-LShift-PrintScr+R,E,I,S,U,B)
Pretty severe. No idea why it took that long to coredump.
Here's a snippet similar to the other posted issue:
CLICK TO EXPAND: Process (polybar) crashed and dumped core.

░░ Subject: Process 52729 (polybar) dumped core

░░ Process 52729 (polybar) crashed and dumped core.
░░
░░ This usually indicates a programming error in the crashing program and
░░ should be reported to its vendor as a bug.
I suspect this is due to pulseaudio coming back up with a different handler/descriptor or something like that and polybar's trying to talk to something that's no longer there. Does not persist through re-launch of polybar - ONLY happens if pulseaudio crashes/bounces while polybar is running. If you restart polybar after pulseaudio is back up and running, polybar's volume slider works again.
To repro:
- Be running polybar with a working volume slider that controls pulseaudio
- Open a terminal and run
pulseaudio -kto bounce pulseaudio - Hover over the polybar volume slider and use the scroll wheel to control the volume, and polybar will crash and dump core.
I have the same issue didn't happen to me before I reinstalled my OS tho did you fix it tho?
