MISC.: Preparing A Minimal Linux Distro (Odriod C4 Example)


# preparing your linux distro
# before following our tutorials and build your audiophile server

# all info below are applicable to Odroid and others boards
# beware official Odroid Linux Kernel version (v3.16.85) is outdated and do not contains the Native DSD patch
# you need version 4.19.64 or greater to play native DSD,
# however selecting DOP MPD audio output will works with limitation

# To build the MusicLounge Audiophile Server we recommended:
# Armbian Focal Linux Distro on Odroid C4,
# RaspiOS lite (Debian) buster for Raspberry PI 4,
# Debian Standard or Ubuntu server for amd64

# before building you audiophile server the software requirements are simple:
# pi user must be set
# ssh must be set
# alsa must be installed and should recognize your usb dac (command: aplay -l )

# get the img from armbian repository
# burn it on SDCARD (8GB is enough) with any tool like Win32DiskImager app on Windows
# connect your usb DAC to Odroid C4
# boot
# and start the ssh session
# default login/pass root/odroid or root/1234

# the root password needed to be changed immediately
# and a new user (non root) must be created (see below)

New root password: ************************
Repeat password: ************************

Choose default system command shell:

1) bash
2) zsh

Shell: BASH

Creating a new user account. Press  to abort

Please provide a username (eg. your forename): pi
Create password: ************************
Repeat password: ************************

Please provide your real name: Pi

Dear Pi, your account pi has been created and is sudo enabled.
Please use this account for your daily work from now on.

# sanity check

  1. $ sudo apt update -y
  2. $ sudo apt upgrade -y

# on armbian ssh is available by default

# on RaspiOS you need to add an empty file named ssh inside the sdcard before booting the OS

# on Ubuntu server amd64 SSH is activated during installation

# on Debian Standard amd64 you need to install openssh-server pkg

# on Debian netinstall you need to install sudo and pi to sudo group

  1. $ su - root
  2. $ apt install sudo
  3. $ usermod -aG sudo pi

# after the first boot add user pi to sudoers on Debian

  1. $ su - root
  2. $ nano /etc/sudoers

# find line root ALL=(ALL:ALL) ALL and add this line

pi ALL=(ALL:ALL) ALL

# save
# CTRL+X then type y and enter
# go back to user

  1. exit

# install ssh server
# not needed on debian netinstall distro as you normally install SSH server during the installation process

  1. $ sudo apt install openssh-server -y

# active service

  1. $ sudo systemctl start ssh
  2. $ sudo systemctl enable ssh

# HEADLESS PC Server (boot without monitor on)
# BEWARE: if you install a distro supposed to work with GUI like Ubuntu/Debian
# and EVEN IF YOU DID NOT INSTALL A USER INTERFACE you may not be able to boot without a monitor!
# fortunately we can fix it by changed a few lines in grub bootloader to get our headless audio server

# edit grub conf

  1. $ sudo nano /etc/default/grub

# and modify the parameters of GRUB_CMDLINE_LINUX_DEFAULT and GRUB_CMDLINE_LINUX to

GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX="text"

# and obviously uncomment this line

GRUB_TERMINAL=console

# SAVE
# CTRL+X then type y and ENTER key

# now update grub

  1. $ sudo update-grub

that’s it!


# optional: if bash auto-completion (automatically completing of file names, commands and more) is not installed by default

  1. $ sudo apt-get install bash-completion

# audio check
# plug your usb DAC and type the cmd below to list soundcard, your dac must be in the list:

  1. $ aplay -l

# alsa should be already installed (not in ubuntu server no soundcard driver by default)
# if your dac is not visible, install ALSA:

  1. $ sudo apt-get install alsa-utils alsa-tools libasound2

# list devices to see if your DAC is recognized

  1. $ aplay -l
root@odroid:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: ODROIDHDMI [ODROID-HDMI], device 0: I2S dit-hifi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: D90 [D90], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

# your usb DAC should be visible in the list

# if still it’s not visible (no soundcard error)
# list installed alsa pkgs, remove them and reinstall alsa
#
# alsa-base pkg could be omited if not present in repository

  1. $ sudo dpkg -l alsa*
  2. $ sudo apt --purge remove alsa-base alsa-firmware-loaders alsa-oss alsa-source alsa-tools alsa-tools-gui alsa-topology-conf alsa-ucm-conf alsamixergui alsa-utils
  3. $ sudo apt-get install alsa-base alsa-utils alsa-tools libasound2
  4. $ sudo reboot

# check alsa status

  1. $ sudo systemctl status alsa-utils.service

# if alsa service is masked unmask it

  1. $ sudo rm /lib/systemd/system/alsa-utils.service
  1. $ sudo systemctl daemon-reload
  1. $ sudo systemctl enable alsa-utils
  2. $ sudo systemctl start alsa-utils

# check the status again everything should be okay

  1. $ sudo systemctl status alsa-utils.service

# on a minimal linux distro with only root you need to create a new user ‘pi’ (or other name) which going to be used to build your MusicLounge audiophile server
# if you’re already login as pi user skip the creation below and go to adding groups directly


# create a user pi:

  1. $ adduser pi
root@odroid:~# adduser pi
Adding user `pi' ...
Adding new group `pi' (1000) ...
Adding new user `pi' (1000) with group `pi' ...
Creating home directory `/home/pi' ...
Copying files from `/etc/skel' ...
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Changing the user information for pi
Enter the new value, or press ENTER for the default
        Full Name []: PI
        Room Number []:
        Work Phone []:
        Home Phone []:
        Other []:
Is the information correct? [Y/n] y

# add new user to all default groups

  1. $ sudo usermod -aG adm,dialout,cdrom,sudo,audio,www-data,video,plugdev,games,users,input,netdev pi
  1. $ groups pi

# reboot, login pi (skip this step if you are already logged in as pi user)

  1. $ sudo reboot
login as: pi

TROUBLESHOOTING: Static IP


# TS7

# Static IP not working
# assign IP to eth0 interface

# configure a static IP address by adding the following to /etc/dhcpcd.conf:

  1. $  ip link show

# ON RASPBERRY PI

  1. 1: lo:  mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
  2. 2: eth0:  mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
  3. 3: wlan0:  mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000

# eth0 is your default interface (Ethernet connection), do not use wifi for your audio server

# ON AMD64 PC

  1. 1: lo:  mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
  2. 2: enp3s0:  mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
  3. 3: wlp2s0:  mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000

# enp3s0 is your default interface (Ethernet connection), do not use wifi for your audio server

# type:

  1. $ sudo nano /etc/network/interface

# add those lines at end:

  1. auto lo eth0
  2. iface lo inet loopback
  3.  
  4. iface eth0 inet static
  5.     address 192.168.x.x
  6.     netmask 255.255.255.0
  7.     network 192.168.x.x
  8.     gateway 192.168.x.x

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

  1. $ sudo nano /etc/resolv.conf

# add one or 2 lines (change IP to your DNS address or your router)

  1. nameserver 192.168.x.x
  2. nameserver x.x.x.x

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

  1. $ sudo reboot

# OPTIONAL AND NOT RECOMMENDED
# stop dhcpcd service when the static ip is valid and reachable only

  1. $ sudo systemctl stop dhcpcd

# restart network

  1. $ sudo systemctl restart networking

# get the status (you may lose your ssh session see below)

  1. $ sudo systemctl status networking

# if everything okay reboot your system

  1. $ sudo reboot

# or type this cmd below with interface name (eth0 or enp3s0 ) and reboot manually

  1. $ sudo ifdown enp3s0

# here you’re loosing your SSH session obviously
# see troubbleshooting if static IP not working
# reboot system
# and start the NEW SSH SESSION WITH YOUR NEW STATIC IP! 😉

TROUBLESHOOTING: GENERAL


# TS6

# if MPD doesn’t start type this to get its status

  1. $ sudo systemctl status mpd

# if the error is related to /libavcodec.so.58: undefined symbol: bcm_host_is_fkms_active
# reinstall libraspberrypi0 pkg

  1. $ sudo apt install --reinstall libraspberrypi0
  1. $ sudo reboot

# NANO return this error (on Armbian / Debian):

Unable to create directory /root/.local/share/nano/: No such file or directory It is required for saving/loading search history or cursor positions.

# check if nano cmd is available using:

  1. sudo /bin/nano .bashrc

# if nano opens the file then you simply need to create the /root/.local/share/nano/ directories
# you can confirm the issue by using:

  1. sudo ls -l /root/.local/

# UPGRADE or DOWNGRADE YOUR KERNEL


# IMPORTANT:
# All information below is for Raspberry PI platform only, does not apply to other devices

  1. $ sudo rpi-install e1050e94821a70b2e4c72b318d6c6c968552e9a2
  1. $ sudo reboot

TROUBLESHOOTING: Raspberry PI 3B+


# IMPORTANT FOR RASPBERRY PI OWNERS:
# It’s strongly recommended to create your audio server on Raspberry PI 4 2Go
# The raspberry pi 3 share the same controller with USB and Ethernet which is not good for an audiophile server
# do not expect to use native DSD with RPI 3 using an usb dac…


# ALL INFORMATION BELOW ARE FOR RPI 3B + ONLY, does not apply to other devices


# Apply patch one by one in this order, reboot and check before


# TS1

# APPLY IF NEEDED ONLY (sound drop/loss)

# Ethernet drops Fix (Recommended for Raspberry PI 3B+ only do not apply to RPI 4)
# identify the name of your Ethernet connection (usually eth0 or enp3s0)

  1. $ ip a

# edit rc.local to run a cmd at startup

  1. $ sudo nano /etc/rc.local

# enter this cmd below to optimize your ethernet connection
# see the Tips & Tricks section to install ethtool (sudo apt-get install ethtool) if needed
# add this line at end of rc.local

  1. $ sudo ethtool -s eth0 speed 100 duplex full

MusicLounge: Introduction

 


# BUILDING THE MUSICLOUNGE AUDIOPHILE SERVER


# STEP1

# A minimum knowledge in shell/bash (typing commands on a terminal using a SSH session with putty for example) is required.
# Internet is your friend! the scope of this project is not to teach linux or how to create a bootable SDCARD from an image file or how to use a SSH session to manage your server wiressly or how to type a command in a shell. 😉
# Simply read carefully instructions and double-check them before applying and everything will be fine.

# the MusicLounge Audiophile Server is reliable and daily used since a while now (more than a decade) and works flawlessly.

# the storage must be already done (see previous post if not ready)

# insert the SD card or USB stick inside the device (Raspberry PI 4, NUC, Ordroid C4, …)

# connect the device to your LAN network using the Ethernet cable (NOT WIFI)

# connect your USB cable from your USB DAC to the device
# (Connecting the usb dac to a powered usb hub maybe required)

# connect your power supply (3A minimum for rPI4 – linear regulated if possible)

# Boot your device!

# for the Raspberry PI 4
# Source code: https://github.com/raspberrypi

# for any barebone PC (Intel NUC, Brix, …)
# Source code: http://cdimage.ubuntu.com/releases/20.04/release/source/

# use “Win32 Disk Image” on Windows to create the SDCARD (8GB)
https://sourceforge.net/projects/win32diskimager/

# use rufus for creating a bootable usb stick with amd64 linux (Intel PC/NUC, Brix,…)
https://rufus.ie/en_US/#

# Notepad++ powerful text editor
https://notepad-plus-plus.org/downloads/

# on barebone PC with internal SSD use HDD Raw Copy 1.10+ Portable from HDGuru.com to clone the img to the SSD


Before going further, the info below is required:
– your gateway / router (internet box) / DNS IP address are required (192.168.x.x)
– if you’re not planning to store musics locally, the ip of your NAS or server PC with the sharing directory containing the music files is required (192.168.x.x)


# VERY IMPORTANT – SSH ON RASPBERRY PI

# RPI4 only: add a empty file named “ssh” without extension (an empty file created with Notepad++ for example) to activate SSH at startup

# RPI4 only: edit cmdline.txt with notepad++ for example and add net.ifnames=0 at the beginning


# Quick Overview:

# create the SDCard with raspiOS or debian lite or armbian or Odroid Ubuntu minimal distro (see the link above)

# DO NOT INSTALL Any Graphics Desktop Environments (GUI), we are building a HEADLESS server…

# insert the SD card inside the device

# connect device to your LAN network using the Ethernet cable

# connect your USB cable from your USB DAC to the device
(for raspberry pi 3b+ connect the usb dac to a powered usb hub and usb hub to the raspberry pi)

# connect your power supply (3A minimum for rPI 4, linear regulated power supply is better)

# Boot your device, start an ssh session from a remote PC and follow our tutorials to install and setup your audiophile server.
