This document contains a list of instructions I followed to configure my ANP.
Hardware:
- Raspberry Pi 3
- HiFiBerry Dac+ pro
- Edimax EW-7811UTC / AC600
- Flirc USB IR receiver
- 7" IPS Display
- Custom build linear power supply with 4 outputs: 3x 5v 2A, 1x 9v 2a
- An aluminium chassis with some CNC work www.modushop.pl
Software:
- Raspbian Jessie Lite
- MPD
- ncmpcpp
- C.A.V.A
- PiFi-Remote a modified subset version of pi.hifi by Bertrand Boichon
btw. I've successfully used volumio for a good while, but I've decided to build something similar but with some extras.
sudo ddrescue -D --force 2016-05-10-raspbian-jessie-lite.img /dev/mmcblk0
sudo raspi-config
Choose option 1 Expand Filesystem
If you don't want to use your SD card reader then you will have to remount the
/boot or /flash partition to rw mode.
mount -o remount,rw /boot
or on some distros
mount -o remount,rw /flash
And then append this to: /boot/config.txt or /flash/config.txt
## enable DAC+ standard/pro
dtoverlay=hifiberry-dacplus
dtdebug=1
If you don't want to remount that partion then simply use your SD card reader
on your PC to edit that config.txt file
The next step is to enable the DAC for ALSA.
Create /etc/asound.conf with this code:
pcm.!default {
type hw card 0
}
ctl.!default {
type hw card 0
}
Lastly, you can disable on-board audio:
sudo vim /etc/modprobe.d/raspi-blacklist.conf
blacklist snd_bcm2835
You can also blacklist any other device/module you want.
Simply use the module names listed with lsmod command
#Disable terminal/screen blanking
sudo vim /etc/kbd/config
# set
BLANK_TIME=0
POWERDOWN_TIME=0
# reboot or restart kbd service
sudo /etc/init.d/kbd restart
Follow this step if you don't want to use the onboard WiFi adapter.
As instructed in the Source link download and extract the
install-wifi script by MrEngman.
# detect the device and check if driver is available
sudo ./install-wifi -c
# then install the driver
./install-wifi 8812au
# generate the PSK for your netwrok
wpa_passphrase <network-SSID> <network-Password> > wpa.conf
sudo mv wpa.conf /etc/wpa_supplicant.conf
# use -Dnl80211 or -Dwext
sudo wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf -Dnl80211
sudo dhclient wlan0
ps. if you're not using the on-board WiFi card then change wlan0 to wlan1
or whatever name system assigned to it.
Once you're happy with your WiFi configuration, then to make it automatically
reconnect after boot-up edit the /etc/network/interfaces
If you're using external WiFi USB dongle and this device is known as wlan1
then it should look more or less like this:
source-directory /etc/network/interfaces.d
auto lo
iface lo inet loopback
iface eth0 inet manual
auto wlan1
allow-hotplug wlan1
iface wlan1 inet manual
pre-up wpa_supplicant -B -D nl80211 -i wlan1 -c /etc/wpa_supplicant.conf
post-down killall -q wpa_supplicant
iface default inet dhcp
If you prefer to use on-board WiFi card then
source-directory /etc/network/interfaces.d
auto lo
iface lo inet loopback
iface eth0 inet manual
auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
pre-up wpa_supplicant -B -D nl80211 -i wlan0 -c /etc/wpa_supplicant.conf
post-down killall -q wpa_supplicant
iface default inet dhcp
You might need to restart the networking service or reboot to get it working.
sudo service networking restart
# or
sudo reboot
This is going to download around 1.5GB of packages so go for a lunch.

This configuration file has 4 outputs defined:
- alsa - to get the sound from from DAC
- mp3 stream - so you can stream your music to your MPD client (ie. MPDroid)
- flac stream - same as above but it will convert the currently playin track to FLAC
- fifo - for ncmpcpp visualizer and/or C.A.V.A.

If you want to add remote cotroller support to your RPi and you have for example a Flirc IR USB receiver then follow the instructions below.
Get the flirc_util for RPi and record the button mappings
wget https://flirc.tv/software/release/gui/linux/Linux_Release.zip
unzip Linux_Release.zip
cd release/rpi/
# Record the button mapping with `flirc_util`
sudo ./flirc_util record escape
sudo ./flirc_util record up
sudo ./flirc_util record left
sudo ./flirc_util record right
sudo ./flirc_util record down
sudo ./flirc_util record enter
sudo ./flirc_util record backspace
sudo ./flirc_util record mute
sudo ./flirc_util record vol_up
sudo ./flirc_util record vol_down
sudo ./flirc_util record play/pause
sudo ./flirc_util record stop
sudo ./flirc_util record fast_forward
sudo ./flirc_util record rewind
sudo ./flirc_util record prev_track
sudo ./flirc_util record next_track
sudo ./flirc_util record pageup
sudo ./flirc_util record pagedown
sudo ./flirc_util record u
sudo ./flirc_util record r
sudo ./flirc_util record x
Then install required Python packages and clone the PiFi-Remote repo
sudo apt-get install python-pip evdev python-mpd2
cd ~/git/
git clone https://github.com/kowalcj0/PiFi-Remote.git
cd PiFi-Remote
Now, you'll have to map the buttons or key codes according to your liking.
# open 2 more terminals and connect to your Raspberry Pi
# on the 2nd one start `PiFiRemote.py`
cd ~/git/PiFi-Remote/pifi
sudo ./PiFiRemote.py
# on the 3rd one monitor the PiFi-Remote log:
tail -f /var/log/pifi-remote.log
Now let's get back to the 1st terminal and edit the key mappings
vim pifi/PiFiRemote.py
Press a button on you IR remote and observe the log. You should see something like:

Find the line that says key event at ...
Take a note of the key (event) code next to the key name (ie. KEY_PAGEUP)
Then use that number to associate it with selected action you want to trigger
In my case I've mapped it to start the song from the begginging (instant reply)
elif event.code == 104:
mpc.play(1)
When you're happy with your button mapping then simply install the package.
cd ~/git/PiFi-Remote
sudo ./setup.py install
This will create a new service, which state you can manage with standard
sudo service pifiremote start|stop|restart
- Log in using your username and password
- Set a password for the "root" account
sudo passwd root - enable SSH logins for root user
sudo vi /etc/ssh/sshd_config
# change `PermitRootLogin without-password` to `PermitRootLogin yes`
- Restart the
sshdservice
sudo service sshd restart
- Log out
- Log in using the "root" account and the password you have previously set
- Change the username and the home folder to the new name that you want
usermod -l <newname> -d /home/<newname> -m <oldname>
- Change the group name to the new name that you want
groupmod -n <newgroup> <oldgroup>
- Lock the "root" account
passwd -l root
- Disable SSH logins for root user
sudo vi /etc/ssh/sshd_config
# change `PermitRootLogin yes` to `PermitRootLogin no`
- If you were using ecryptfs (encrypted home directory). Mount your encrypted directory using ecryptfs-recover-private and edit
<mountpoint>/.ecryptfs/Private.mntto reflect your new home directory. - Log out
- Log back in as the new user
- Edit the
/etc/hostsand change127.0.1.1 pito127.0.1.1 your_new_amazing_network_name - Then edit the
/etc/hostnameand changepitoyour_new_amazing_network_name - Reboot
From now on, your Pi will be accessible via:
your_new_amazing_network_name.home or your_new_amazing_network_name.local hostname :)
Change 4 occurences of username pi to your_new_username in /usr/bin/raspi-config
I'll use mpd as my username
sudo vim /usr/bin/raspi-config
#...
"B2 Console Autologin" "Text console, automatically logged in as 'mpd' user" \
#...
"B4 Desktop Autologin" "Desktop GUI, automatically logged in as 'mpd' user" \
#...
sed /etc/inittab -i -e "s/1:2345:respawn:\/bin\/login -f mpd tty1 <\/dev\/tty1 >\/dev\/tty1 2>&1/1:2345:respawn:\/sbin\/getty --noclear 38400 tty1/"
###...
sed /etc/inittab -i -e "s/1:2345:respawn:\/sbin\/getty --noclear 38400 tty1/1:2345:respawn:\/bin\/login -f mpd tty1 <\/dev\/tty1 >\/dev\/tty1 2>&1/"
- Then launche the
raspi-configasroot - Choose option
3 Boot Options - Choose option
B2 Console Autologin
Next time you're going to boot up your RPI it will automatically login as that user.
I don't know why MPD didn't register itself as a new system service, so to start it up
on login simply modify your .profile
vim ~/.profile
mpd; wait
