Autostart pulseaudio after boot

[michael123]

Hej there,
I have a fresh installed arch on my Raspberry Pi Model B+ and want to use
it as a pulseaudio-server so I can stream my audio from my notebook to the pi/old school stereo.
Until here everythings works fine, if I log in on the Pi as a nonroot user and start pulseaudio manually I can stream the audio.
Therefor I folllowed the guide from the wiki https://wiki.archlinux.org/index.php/Pu … er_network
Now it would be nice if pulseaudio would start after boot of the Pi automatically.
In the Documentation of pulseaudio I found the Option
autospawn = no
in the file /etc/pulse/client.conf which is by default set to no. Changing it to "yes" doesn't make a difference.
Can anybody please explain this option?
There is apparently another way I found by research: Setting pulseaudio in system-mode which can be done by the option
$this->bbcode_second_pass_code('', 'system-instance = yes')
in the file /etc/pulse/daemon.conf
To start pulseaudio now after boot i tried to use systemd by creating the file /etc/systemd/system/pulseaudio.service
$this->bbcode_second_pass_code('', '
# systemd service spec for pulseaudio running in system mode -- not recommended though!
# on arch, put it under /etc/systemd/system/pulseaudio.service
# start with: systemctl start pulseaudio.service
# enable on boot: systemctl enable pulseaudio.service

ExecStart=/usr/bin/pulseaudio --system --disallow-exit --disallow-module-loading
ExecReload=/bin/kill -HUP $MAINPID

But when I try to start the service by
$this->bbcode_second_pass_code('', '
systemctl start pulseaudio.service')
I got the following output
$this->bbcode_second_pass_code('', '
[michael@raspberry ~]$ systemctl status pulseaudio.service

I read on the pulseaudio website that systemwide mode is not recommended. Is there some other way to start pulseaudio after boot without logging in and maybe not in systemwide mode since it's not recommended?
Thank in advance!

$this->bbcode_second_pass_code('', 'Feb 01 02:12:21 raspberry pulseaudio[278]: Failed to find user 'pulse'')
That's a fairly direct clue.
