xfce4-pulseaudio-plugin: Completely unresponsive and freezes X server

Hello,

The PulseAudio panel plugin on my system does not respond to inputs and any attempt to interact with the applet or its preferences panel results in the X server being uninteractable. By that I mean that I cannot click on or use (nearly) any hotkeys to interact with the system. I must switch TTY and restart the desktop manager (systemctl restart lightdm) to fix the issue.

Oddly, the panel plugin freezes the system anywhere from 30 seconds to 5 minutes after attempting to interact with it. So far I have tried the following:

- Backed up and removed XFCE configuration for testing
- Removed PulseAudio configuration for testing
- Switched from PulseAudio to PipeWire

Nothing has made a difference. I hoped the 4.16 update might make a difference, but it hasn't. Perhaps there is a conflict somewhere, though I am struggling to find it. Could anyone please lend me their aid and terminal-level voodoo?

Re: xfce4-pulseaudio-plugin: Completely unresponsive and freezes X server

Hello. Hopefully I won't get into trouble for necro'ing an old thread.

Just in case anyone is searching and comes across this.

I hit this problem today in 2022, and I've seen a couple of other forum posts about it, with NO reply from anybody.

The only thing I found that fixed it was a complete purge of pulseaudio, as below, but keep reading before you just cut and paste into a root window and hit return!

For one thing at least, PLEASE DO THIS dpkg-query FIRST!

dpkg-query --no-pager -l > dpkg.apps.installed.before.I.purged.pulseaudio.txt

Then the scary part:

apt-get -y purge gstreamer1.0-pulseaudio:amd64 libkf5pulseaudioqt2:amd64 libpulse-mainloop-glib0:amd64 libpulse0:amd64 libpulse0:i386 libpulsedsp:amd64 libsdl1.2debian-pulseaudio pulseaudio pulseaudio-utils xfce4-pulseaudio-plugin:amd64

Then I did the reverse, 'install', to put it all back. (Note the SDL library couldn't find a candidate so I just removed it from the list).

Now the thing is, this removed a HEAP of apps that 'vaguely depended on' pulseaudio.  I'm still reinstalling them.

I did a mass automated reinstall from a before-and-after diff of dpkg, but IT BROUGHT THE PROBLEM BACK!  So something in there is the culprit, or a combination is. The list was far too complex and deep to bother even trying to debug it.

Looking forward to trying out pipewire and removing all trace of pulseaudio from my system one day! (And indeed systemd, thinking about MX Linux).

Incidentally I reinstalled PulseEffects (pulseeffects) and the problem did not return, so for me pulseeffects was not the issue.
