[pulseaudio-discuss] pulseaudio still running before shutdown

my system: Linux/Lubuntu 18.04.2 LTS, 64 bit

I shut down my system with the terminal-command "shutdown -H -P +0" or
"poweroff". But the observed phenomenon may also be seen when
shutting down from the panel.

I changed my grub-config from GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to GRUB_CMDLINE_LINUX_DEFAULT="noplymouth" in order to get screen output
of the logs.

And here I see an entry reading "failed unmounting /home" (in red).
After that came some more messages which all were O.K. Everything else
was in green with an "O.K." in front.

I don´t know why I get this message because the shutdown works well
despite that error message. In fact it shuts down really fast.

So I took alook at journalctl. It shows me the following:

Apr 05 18:16:19 rosika-Lenovo-H520e umount[25556]: umount: /home: das
Ziel wird gerade benutzt. # /home is currently in use
Apr 05 18:16:19 rosika-Lenovo-H520e systemd[1]: Unmounting
Apr 05 18:16:19 rosika-Lenovo-H520e systemd[1]: Unmounting
Apr 05 18:16:19 rosika-Lenovo-H520e systemd[1]: home.mount: Mount
process exited, code=exited status=32
Apr 05 18:16:19 rosika-Lenovo-H520e systemd[1]: Failed unmounting /home.
# <-------------

I found out that a pulseaudio process seems to be the culprit.

So I looked up the proceses before shutdown:

ps -ax | grep -i pulseaudio
 1515 ?        Sl     0:00 /usr/bin/pulseaudio --start --log-target=syslog
 2348 ?        Sl     0:01 /usr/bin/pulseaudio --start --log-target=syslog
 3820 pts/2    S+     0:00 grep --color=auto -i pulseaudio

There are two pulseaudio processes running (!). I don´t know why. This
is the state immediately before shutdown. All programmes are closed
and nothing should be running regarding pulseaudio.

So I perform " killall pulseaudio" immediately before shutdown. After
that I get no error messages at all.

Does anybody know what can be done about this?

Tnx a lot in advance.
