Add IR Remote Control

Linux Audio Team

# STEP16

# OPTIONAL: Add A Remote Control Management
# this tutorial and the next one is about controlling the audio server with a remote control to play, pause, stop, go next / prev song, launch playlist, drive equalizer,…
# this one use a very easy to use tool named Triggerhappy and the other use Lirc a more complete implementation supporting hundreds remote controls
# IMPORTANT: some devices like Intel NUC needs to enable Enhanced Consumer IR in BIOS to work with remote control

# Add a remote control management

# install triggerhappy (should be already installed)

  1. $ sudo apt-get install triggerhappy

# create a configuration file
# pressing ZERO button select the default (first) audio output

  1. $ sudo nano /etc/triggerhappy/triggers.d/triggers.conf


# add your key to play, stop,… copy/paste the lines below:
# in addition to the standard play, stop, pause,… commands,
# this remote control config will
# start playing playlist 1 to 3 random order by pressing the corresponding key 1, 2 or 3
# select 2 EQ setup by pressing key 6 or 9
# select the default audio output (NO EQ) by pressing 0 (zero)

  1. $ sudo systemctl enable triggerhappy


  1. $ sudo systemctl start triggerhappy


  1. $ sudo systemctl status triggerhappy

# DEBUG THE KEY CODES
# useful if your remote control is not working, skip this during install
# if your remote control do not send the correct key use the dump function to identify the correct key and change your cmds in triggers.conf
# To dump all events received through your remote control (useful to get the corresponding keys):

  1. $ sudo thd --dump /dev/input/event*

# CTRL+C to exit

# OPTIONAL
# if you need to run script as root from triggerhappy (default user is nobody) do the following:
# giving root access is risky but if know what you’re doing this can be useful to run script to set parametric EQ or load playlist with the remote
# useful to drive ALSAEQ (equalizer plugin) for example

  1. $ sudo nano /lib/systemd/system/triggerhappy.service

change
–user nobody
to
–user root

# CTRL+O to save
# CTRL+X to exit

  1. $ sudo nano /etc/default/triggerhappy



# comment

#DAEMON_OPTS=""

# uncomment

DAEMON_OPTS="--user root"

# CTRL+O to save
# CTRL+X to exit

  1. $ sudo systemctl daemon-reload


  1. $ sudo systemctl restart triggerhappy


  1. $ sudo systemctl status triggerhappy

# add a playlist script
# if you followed our tutorials the playlist/ and scripts/ directory are already created

# from a remote PC, open the share point playlists and copy 2 playlists into it
# for example my_classical_albums.m3u and my_jazzy_albums.m3u

# create the script

  1. $ sudo nano ~/scripts/playlist1.sh
#!/bin/bash
#
# Script to load playlist
 
echo "start playlist"
mpc stop
mpc clear
mpc enable only 1
mpc load my_classical_albums
mpc random "on"
mpc crossfade 0
mpc play

# CTRL+O to save
# CTRL+X to exit

# set exec permission

  1. $ sudo chmod +x ~/scripts/playlist1.sh

# create the script

  1. $ sudo nano ~/scripts/playlist2.sh

mpc random "on"
mpc crossfade 0
mpc play

# CTRL+O to save
# CTRL+X to exit

# set exec permission

  1. $ sudo chmod +x ~/scripts/playlist2.sh

# now pressing key 1 or 2 of the remote control plays the playlist classical or jazzy

# obviously for this to work you need to save your playlists in the playlists directory

# in our example of configuration above we have key 6 and 9 assigned to ALSA EQ,
# by pressing key 6 or 9 you are going to trigger the lowbass.sh or the jbjeq.sh which drive the ALSA Equalizer plugin to shape your sound

TROUBLESHOOTING

# if for some reason myMPD fails at startup, it’s almost certainly a permission issue
# due to an upgrade from old version to the recent version of myMPD

mympd.service: Failed to set up special execution directory in /var/cache: File exists


# the new version of myMPD no longer uses a static ‘mympd’ group/user but the
# DynamicUser feature of systemd which automatically attributes the correct user and group
# to all myMPD directories at startup

# to cleanup your installation do the following
# (all cache and configuration files will be deleted)

  1. $ sudo systemctl stop mympd
  2. $ sudo rm -Rf /var/lib/mympd
  3. $ sudo rm -Rf /var/lib/private/mympd
  4. $ sudo rm -Rf /var/cache/private/mympd
  5. $ sudo rm -Rf /var/cache/mympd
  6. $ sudo userdel mympd
  7. $ sudo groupdel mympd

# to create initial configuration with the new version using systemd:

  1. $ sudosystemd-run -t -p DynamicUser=yes -p StateDirectory=mympd -p CacheDirectory=mympd /usr/bin/mympd -c

# now the directories are re-created by myMPD and user/group assigned by systemd,
# configure http port to 8080
# edit and replace 80 to 8080 and CTRL+X to save

  1. $  sudo nano /var/lib/mympd/config/http_port

# deactivate SSL
# replace true to false and CTRL+X to save

  1. $ sudo nano /var/lib/mympd/config/ssl

# reboot

  1. $ sudo reboot

# start myMPD with the correct config and check the status.

  1. $ sudo systemctl start mympd

# if the album cover are not visible in database view, you may try to change the music directory to NONE

# Everything should be okay.

Update MPD Database

Linux Audio Team

# STEP14

# Congrats! MPD is installed and running!

# First Steps With Music Player Daemon

# it’s now time to update the tag db of MPD, we are using the client this time (mpc):
# type the following cmds to update the MPD database

  1. $ mpc update

# check the status to see if the update is done type:

  1. $ mpc status

# “Updating DB …” shouldn’t be in the status result (can take a while be patient, 1500 albums/19000 songs is about 10mn to be updated)

# loop with

  1. $ mpc status

# until the DB is updated

# STEP15

  1. $ mpc status

# play songs to check if everything is OKAY! 😉

Configure MPD

Linux Audio Team

# STEP10

# YOUR USB DAC MUST BE CONNECTED TO THE USB PORT AND READY

# edit the configuration of MPD with a DAC USB connected but before:

# identify your USB DAC ID (usually card 1):

  1. $ aplay -l

# in case of *No Soundcard Error*, read our tutorial to install ALSA correctly and prepare your Linux distribution

# to list of playback hardware devices (card 0, card 1, car 2….) and to get the index of your USB DAC

# report this index number in the line device “hw:x,0” of all audio output in mpd.conf see below

# the USB DAC should be indexed 1 or 2

# BEWARE if you disable the RASPBERRY PI HDMI port later (see the corresponding howto) the ID of your DAC will certainly change which require to modify mpd.conf audio output as well

# If your sound card order changes on boot, you can “play” with /etc/modprobe.d/alsa-base.conf to specify its order. For example, if you want your snd_usb_audio (USB DAC) card to be #1:

options snd_usb_audio index=1

You can also provide an index of -2 to instruct ALSA to never use a card as the primary one and ensure USB DAC never getting index 0:

options snd_usb_audio index=-2

This will change the order of the devices in the list (read the ALSA doc online to get more info on alsa-base.conf).

# check the card IDs after reboot with

  1. $ aplay -l

# OPTIONAL: You can skip this step if a server distribution is installed
# but for desktop distro you have to disable MPD user service
# because you run it as a headless server:

  1. $ sudo rm /etc/xdg/autostart/mpd.desktop
  2. $ sudo systemctl --global disable mpd.service
  3. $ sudo systemctl --global disable mpd.socket

# TROUBLESHOUTING

# if the error is releated to audio device not found, read again the first chapter of this tutorial to configure modprobe correctly and ensure your USB DAC card ID is 1 or edit all your configuration including MPD to change the plugin hardware id (“plughw:X,0”)

Local Music Library Or USB Hard Drive

Linux Audio Team

# using a local music library is very easy, simply add all your music inside /mnt/media, this folder is shared on the local network and is also available from host \\MUSICLOUNGE\music (read the SAMBA configuration for more info)

# using an external USB hard drive for your music library is also easy but the disk must be powered (even an SSD) with an external adapter.

# so make sure the usb hard drive is powered with an external adapter and plug the usb cable on the server board (rPI 4 or C4 or Pc),

Install exFAT File System

# exFAT file system is not installed by default on all distributions and you may need it
# to install exFAT do the following:

  1. $ sudo apt-get install exfat-fuse
  2. $ sudo apt-get install exfat-utils
  3. $ sudo reboot

Configuration

# start to list disks attached to find where is located

  1. $ sudo fdisk -l
Device Boot Start End Sectors Size Id Type
/dev/sda1 63 1953520064 1953520002 931.5G 7 HPFS/NTFS/exFAT

# /dev/sda1 is our usb hard drive location


# now get its UUID and file system

  1. $ sudo blkid
/dev/sda1: LABEL="SAMSGBKUP" UUID="9A2B-8FC2" TYPE="exfat" PARTUUID="5b0a6a10-01"

# here we have 9A2B-8FC2 as UUID and exfat file system

Auto-Mounting Drive

# normally if the MusicLounge audiophile server is correctly installed the /mnt/media directory is already there, check this:

  1. $ ls /mnt/media

# creates the directory if needed:

  1. $ sudo mkdir /mnt/media

# edit fstab to mount the disk at startup

  1. $ sudo nano /etc/fstab

# add this line WITH YOUR UUID and correct file system

# comment with # prefix any other line with /mnt/media)

UUID=9A2B-8FC2 /mnt/media exfat defaults,auto,umask=000,users,rw 0 0

# CTRL + X and Y to save

# before rebooting it’s important to test your fstab configuration

  1. $ sudo mount -a

# edit and check fstab configuration again if the command return an error

# reboot

  1. $ sudo reboot

# check your music library 

  1. $ ls /mnt/media

Update MPD Database

# to update database use your favorite MPD client (MALP or DroidMyMPD or myMPD on your web browser) or open SSH session and type:

  1. $ mpc update

# that’s it!
# your music library is now on local disk

Tips

# to mount an exFat hard dive manually

  1. $ sudo mount -t exfat /dev/sda1 /mnt/media

# to unmount

  1. $ sudo umount -f /mnt/media
