DIY Network Audio Player

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.

Flash Raspbian Jessie lie

sudo ddrescue -D --force 2016-05-10-raspbian-jessie-lite.img /dev/mmcblk0

Expand filesystem size to the max size of your card

sudo raspi-config

Choose option 1 Expand Filesystem

Enable HiFiBerry DAC+ Pro

Source

/boot/config.txt

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

/etc/asound.conf

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
}

Disable on-board audio

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

Source

sudo vim /etc/kbd/config
# set
BLANK_TIME=0
POWERDOWN_TIME=0

# reboot or restart kbd service
sudo /etc/init.d/kbd restart

Get WiFi driver

Source

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

Configure WiFi connection

# 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

MPD configuration

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.

PiFi Remote

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.

Map your IR remote controller codes (buttons) to regular keyboard key presses

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)

Install PiFi-Remote service

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

Change the default user name

Source

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 sshd service

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.mnt to reflect your new home directory.
Log out
Log back in as the new user

Change the device network name

Edit the /etc/hosts and change 127.0.1.1 pi to 127.0.1.1 your_new_amazing_network_name
Then edit the /etc/hostname and change pi to your_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 :)

Console Autologin

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-config as root
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.

Start MPD and C.A.V.A on autologin

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
