I2S DAC Support

Linux Audio Team

MusicLounge do not support I2S audio dac by default but it’s really easy to add the support of such cards.

Example 1 with Hifiberry DAC Plus RCA and Hiffiberry DAC+ PRO on Raspberry PI 4

Example 2 with Hifi Shield 2 (RCA) on Odriod C4

1- HIFIBERRY DAC And Raspberry PI 4

Make sure the board is correctly connected to the PI 4 and to the power supply (5V 3A)

# edit config.txt

pi@musiclounge:~ $ sudo nano /boot/config.txt

# add at end 

dtoverlay=hifiberry-dacplus

Subdevices: 1/1
Subdevice #0: subdevice #0

The trick here is to keep dtparam=audio=on (native headphone) to shift Hifiberry DAC to card number 1 to be dirrectly compatible with MusicLounge audio server settings.

if card number is different go HERE to reconfigure MPD and other audio services

and if you use the alsa equalizer plugin do not forget to change the plughw id in .asoundrc, see the tutorial here

here is a basic setup of the mpd output audio for hifiberry dac

audio_output {
type "alsa"
name "Hifiberry"
device "hw:1,0"
mixer_type "hardware"
mixer_control "Digital"
mixer_device "hw:1"
mixer_index "0"
dop "yes"
}

2- HIFI SHIELD 2 AND ODROID C4

Make sure the board is correctly connected to the C4 and to the power supply ( more info available HERE ).

# Edit /media/boot/config.ini to edit the DTBO settings. Open that file and find the part shown below. The below settings different from the default, it adds a new section named overlay_hifishield and uses that section by the overlay_profile variable.

@musiclounge:~ $ sudo nano /media/boot/config.ini

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

Linux Audio Team

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

# our ready to use audiophile server distribution image disk (MusicLounge) is available here

# all info below are applicable to Odroid and others boards like raspberry PI or barebone PC
# beware official Odroid Linux Kernel version (v3.16.85) is outdated and do not contains the Native DSD patch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 or Jammy Linux Distro on Odroid C4,
# RaspiOS lite (Debian) buster or Bulleyes for Raspberry PI 4,
# latest stable Debian Standard or Ubuntu server for amd64 (buster or bullseye)

# MPD version 0.23.12 and 0.22.8 for old distribution
# myMPD version 10.2.0 and 10.7.1 for old distribution

# 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 repository (armbian, raspberry, debian)
# burn it on SDCARD (8GB is enough) with any tool like Win32DiskImager app on Windows
# connect your usb DAC
# boot
# and start the ssh session
# default login/pass:
# on odroid: root/odroid or root/1234
# on raspberry PI: pi/raspberry
# on amd64 Debian: root password is created during the installation
# on our MusicLounge distro: pi/musiclounge

# 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
