Raspberry Pi Setup As MPD Sever

Setup MPD on Raspberry Pi:
Credit to the tutorial below:

I've some updates on top of it...
1. Download arch linux image from ArchLinux Raspberry Pi page:
http://archlinuxarm.org/platforms/armv6/raspberry-pi

2. Load the image to a SD card with 2G or more. Win32 Disk Imager is recommended:
http://sourceforge.net/projects/win32diskimager/

3. After loading the image, put the card into Pi and power up, wait for 1 minute, then use IP scanner to find the IP address of Pi, just pick one below or google for others.

4. Putty to that IP at port 22

5. login ID is "root", password is "root"

6. Make private key for auto authenticate (optional)
You may follow the tutorial below for detail setup procedure:

7. Change timezone
Run the tzselect script to figure out which timezone you should be in, then note the output – in my case its America/Toronto.
Add the following text to a new file called /etc/profile.d/timezone.sh – this will cause the timezone to be set whenever a user logs in.

TZ='Asia/Hong_Kong

export TZ

Don’t forget to make the new file executable!

chmod 755 /etc/profile.d/timezone.sh

8. Add Alsa sound output

pacman -Sy

pacman -S alsa-utils

9. Install Music Player Daemon (MPD)

pacman -S mpd mpc

10. Add users for MPD

usermod -G audio -a mpd

11. One-time setup for MPD

mkdir -p /var/lib/mpd/music
chown mpd:mpd /var/lib/mpd

mkdir -p /var/log/mpd
touch /var/log/mpd/mpd.log
chown mpd:mpd /var/log/mpd

12. Edit /etc/mpd.conf

Add or uncomment the following:

music_directory         "/var/lib/mpd/music"
playlist_directory "/var/lib/mpd/playlists"
db_file "/var/lib/mpd/mpd.db"
log_file                        "/var/log/mpd/mpd.log"
state_file "/var/lib/mpd/mpdstate"
bind_to_address         "any"

zeroconf_enabled                "yes"
zeroconf_name                   "Pi + ArchLinux"

audio_output {
        type            "alsa"
        name            "On-board Audio"
        device          "hw:0,0"
}

audio_output {
        type            "alsa"
        name            "USB DAC"
        device          "hw:1,0"
}

(A brief summary:
To make sure the directories for music, log, db etc be consistent.
To make sure zero_conf is turned on
To make sure two audio output devices (using alsa) are defined)

12. Test MPD
Open another putty session, run command:
