            Bug ID: 105799
           Summary: Pulseaudio prevents /home from unmounting
           Product: PulseAudio
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: All
            Status: NEW
          Severity: critical

Hi,

I run Fedora 27/28 with Gnome 3.26/3.28 but without gdm (so booting to
multi-user.target and starting Gnome with startx). Everything works fine.
However whenever I play audio and after that log out to the console again, I
see with lsof /home that there are a small number of open files. The only
interesting things are the files related to Pulseaudio in my ~/.config/pulse.
Pulseaudio is running according to htop. 

So I figure it has something to do with Pulseaudio in my case. When I quit from
X11 and do pulseaudio -k and then reboot or shutdown, than no error concerning
failed unmounting occurs.

The bug also occurs when playing sound from the console (without X) and quiting
that and rebooting after that. Pulseaudio is preventing /home from cleanly
unmounting. I am afraid for data corruption if this is not resolved. 

My /home is a simple ext4 (with no encryption) on a different partition on
SDA1.

I have spend many hours trying to debug this problem. I have the issue on both
of my laptops and my desktop (1 running Fedora 28 and 2 running Fedora 27).

On Fedora 27 the version of Pulseaudio is 11.1-15.fc27. I originally assumed
the bug was related to systemd, see this bug where everything is explained in
detail (https://github.com/systemd/systemd/issues/6956).
