[SOLVED]MPD, PulseAudio & Systemd/User

Question

Since the advent of skype 4.3 I've had to switch to using pulseaudio. Things seems to be working fine except for the interaction between pulseaudio and mpd. My goal is to attain the same functionality as I had before when I was just using alsa. The main problem seems to be that the mpd daemon starts before pulseaudio. This means that when I reboot, for example, my music doesn't automatically keep playing. However if I toggle mpc (or open ncmpcpp and unpause) then it works fine.
What I have done
1) I installed mpd using the script found on the wiki
1a) copied ~/.config/mpd/mpd.conf to /etc/mpd.conf and uncomment #user line so it runs as my user
1b) enabled the mpd service with systemctl so it starts on boot, as directed to from 1)
2) Applied the workaround detailed here to make pulseaudio play nice with mpd
From what I can understand this results in the mpd daemon using the /etc/mpd.conf file which mirrors my local one (but I think the process is still started as root?)
If I don't do 2) then I get a problem where if I try to open pavucontrol I get an error saying I'm unable to connect and the system feels very unresponsive. Two second delays navigating around in thunar for example.
fuser /dev/snd/* outputs
» sudo fuser /dev/snd/*
/dev/snd/controlC0: 440
/dev/snd/controlC1: 440
/dev/snd/pcmC0D0p: 440m
» ps aux | grep 440

quiv 2259 0.0 0.0 11668 2296 pts/0 S+ 15:23 0:00 grep --color=auto 440
For now I have added in
if grep -q "state: pause" /home/quiv/.config/mpd/state; then
mpc toggle
fi
to my ~/.xinitrc as a work around to get pulse and mpd to work together properly. However it doesn't seem to work all the time. If I leave my music playing then when I reboot the system with reboot it seems that somtimes the state is being saved as paused, and other times as play. I suppose I could just mpc toggle without checking, but I don't want a situation where if I happen to not be playing music that every time I reboot my music starts playing.
Other things I have tried are;
A) not using pulseaudio with mpd.
B) not using systemd to manage mpd. Instead I manually started it in .xinitrc and pointed it to my ~/.config/mpd/mpd.conf file. I believe this means it runs as my own user instead of as root. When I did this I commented the username line and also undid 2) from above in ~/.config/mpd/mpd.conf
The problem with A) is that if I use alsa with mpd, mpd hogs my soundcard. My card becomes unselectable in pavucontrol and I cannot use it with pulseaudio., meanng no skype. The benefit of doing this (this is how I used to do it before I needed pulseaudio) is I have no problems with mpd's state being saved incorrectly.
The problem with B) is the mpdstate is saved incorrectly when for example I issue reboot. I can reproduce this by changing my currently played song then rebooting. When I boot back up mpd resumes playback from the previous session instead of recognizing the last thing I was playing. I had a search around on the forums and I found this issue which seems to describe what is happening. There doesn't seem to be a solution there instead a suggestion to user systemd (which I would like to do!) instead to manage mpd. Rasi's post details a unit file but I'm unsure what to do with this.
Looking at the wiki it seems like maybe I am supposed to provide this file so that it overwrites the default mpd.service unit. So I followed the steps listed there. First I created the directory /etc/systemd/system/mpd.d/ then made the user.conf file inside. I tried just putting the additional arguments in
[Service]
User=YOUR_USER
PAMName=system-local-login
I also remember trying to overwrite the entire [Service] section of the original by using
[Service]
User=YOUR_USER
PAMName=system-local-login
ExecStart=
ExecStart=/usr/bin/mpd --no-daemon
because I think just adding the addtional parameters might not have worked. But I'm not sure on this point, maybe both ways worked. This seemed to work but I had the same problem as above. The state was still being saved incorrectly sometimes when I rebooted. I would get a previous session instead of the most recent change. So I tried the other method for overwriting systemd unit files and made the file /etc/systemd/system/mpd.service in which I pasted Rasi's entire unit file. This also seemed to work, but still the incorrect state problem happened.
At this point I didn't know what to try. It seemed like the only option left was to set up mpd using a local configuration and setting up a systemd/User session and managing it that way. The wiki indiciated that if I did it this way I would not have to use the method 2) above. However I was/still am hesistant about doing this. I'm new to arch and the systemd/User wiki page seems very intimidating. I worry that I will create problems that I won't understand how to solve using this method just for the chance that mpd will function correclty with pulse. However I seemed to have exhausted all my possible options so I thought whatever I'll try it anyway! I'm certain I probably haven't done it right however.
So once again I turned to the wiki to help me with setting this up. However I can't make sense of the article. I don't know if I should follow ONLY the Setup since systemd 206 or if I should follow both setup sections? I decided to follow only the first section. I use no DE so I commented out the
[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && exec startx
line in my ~/.zprofile. When I set up my system I followed the Automatic login to virtual console. I left this file alone, but upon second thoughts maybe I should have disabled this too? I don't understand if using xlogin-git to austoart Xorg, as described in the systemd/User page, requires me to get rid of this too. I think xlogin-git just starts Xorg so automatic login via getty should be fine?
Immediately when I boot in using systemd to manage my session I notice that there are problems. I don't think my environment variables are being sourced from .zshenv because my panel fails to load. If I kill the panel and load it again it works. This makes me think there is something wrong with the order of units started with systemd.
» sudo journalctl --this-boot --no-pager | grep -i panel ~
Jul 05 16:25:39 lorelai bash[494]: /home/quiv/.config/bspwm/panel/panel: line 16: : No such file or directory
Jul 05 16:25:39 lorelai bash[494]: /home/quiv/.config/bspwm/panel/panel: line 17: : No such file or directory
Jul 05 16:25:39 lorelai bash[494]: /home/quiv/.config/bspwm/panel/panel: line 18: : No such file or directory
In each instance panel is trying to do things based on $PANEL_FIFO which is exported from ~/.zshenv but it doesn't appear to be set at the time systemd starts things up. Apart from these problems, which are probably undoubtedly due to the fact I failed to set up systemd/User properly, I still have problems with mpd. The state seems to be remembered correctly now, however when I reboot I still have to toggle mpc for it to start playback. It seems to be the same problem as when I use setup detailed intially. I suspect perhaps once again there is something wrong with the order here. MPD starts before pulse so it doesn't find anything to play through, then once I issue the mpc toggle command pulse is started and all is happy.
A final note is that I was getting this error yesterday when using systemd/User
● mpd.service - Music Player Daemon

but it doesn't seem to happen anymore.
Also I have no idea if I'm even supposed to use it like this but
» sudo systemctl --user enable mpd ~
Failed to get D-Bus connection: Connection refused
I tried this because I was wondering if mpd was even using the correct service when using systemd/User. I thought perhaps it just was using the one in /etc/systemd/system/ instead of /usr/lib/systemd/user/. I'm still not sure about this.
In the end I've exhausted whatever I can think of. I'm sure I've done a lot of things wrong but I tried my best. Hopefully somebody knows what I've done wrong and can help me.

# Normalization automatic volume adjustments ##################################
# This setting specifies the type of ReplayGain to use. This setting can have
# the argument "off", "album", "track" or "auto". "auto" is a special mode that
# chooses between "track" and "album" depending on the current state of
# random playback. If random playback is enabled then "track" mode is used.
# See <http://www.replaygain.org> for more details about ReplayGain.
# This setting is off by default.
replaygain "album"
# This setting sets the pre-amp used for files that have ReplayGain tags. By
# default this setting is disabled.
replaygain_preamp "0"
# This setting sets the pre-amp used for files that do NOT have ReplayGain tags.
# By default this setting is disabled.
#replaygain_missing_preamp "0"
# This setting enables or disables ReplayGain limiting.
# MPD calculates actual amplification based on the ReplayGain tags
# and replaygain_preamp / replaygain_missing_preamp setting.
# If replaygain_limit is enabled MPD will never amplify audio signal
# above its original level. If replaygain_limit is disabled such amplification
# might occur. By default this setting is enabled.
#replaygain_limit "yes"
# This setting enables on-the-fly normalization volume adjustment. This will
# result in the volume of all playing audio to be adjusted so the output has
# equal "loudness". This setting is disabled by default.

# This setting adjusts the size of internal decoded audio buffering. Changing
# this may have undesired effects. Don't change this if you don't know what you
# are doing.

# This setting controls the percentage of the buffer which is filled before
# beginning to play. Increasing this reduces the chance of audio file skipping,
# at the cost of increased time prior to audio playback.
#buffer_before_play "10%"
# Resource Limitations ########################################################

# resources. Generally, these settings should be minimized to prevent security
# risks, depending on the operating resources.

Well shit. I guess I didn't need to do all that other stuff. I only wish I'd known about this before wasting most of my day. Thank you very much, everything appears to be working flawlessly now.
