Comment 11 for bug 2051570

I did the modification :
[Unit]
Description=Sound Service

# We require pulseaudio.socket to be active before starting the daemon,
because
# while it is possible to use the service without the socket, it is not
clear
# why it would be desirable.
#
# A user installing pulseaudio and doing `systemctl --user start pulseaudio`
# will not get the socket started, which might be confusing and problematic
if
# the server is to be restarted later on, as the client autospawn feature
# might kick in. Also, a start of the socket unit will fail, adding to the
# confusion.
#
# After=pulseaudio.socket is not needed, as it is already implicit in the
# socket-service relationship, see systemd.socket(5).
Requires=pulseaudio.socket
ConditionUser=!root

[Service]
ExecStart=/usr/bin/pulseaudio -vvvv --daemonize=no
--log-target=file:/home/$USER/pulse.txt
LockPersonality=yes
MemoryDenyWriteExecute=yes
NoNewPrivileges=yes
Restart=on-failure
RestrictNamespaces=yes
SystemCallArchitectures=native
SystemCallFilter=@system-service
# Note that notify will only work if --daemonize=no
Type=notify
UMask=0077
Slice=session.slice

[Install]
Also=pulseaudio.socket
WantedBy=default.target

However, after rebooting the system, I couldn't locate the pulse.txt file
in my home directory (/home/$USER/) or by searching it, and have confirmed
that hidden files are visible.

On a positive note, I noticed that I can now choose the headphone
microphone from the input device list without the need to delete and
re-setup the headphone from the Bluetooth settings.
Thanks for the help.
