PART2: Cloning AMD64 UEFI Image Disk From Windows

April 26, 2023April 26, 2023 Linux Audio Team

# we assume you have a PC with Windows system and 7zip (or Winrar) installed
# and GParted Live USB stick bootable

# more info on GParted website to create your a bootable Live system)
# and another USB drive for the image disk

WINDOWS PC

# download the distribution from our website/github and extract it with 7zip (or Winrar)
# insert your USB drive and format it using NTFS with for example ‘imgdisk’ name
# then copy the extracted image disk (.img) from Windows to your USB drive
# optional: rename image disk to musiclounge.img or medialounge.img

BAREBONE PC (HTPC)

# insert the the GParted Live USB, the imgdisk usb stick, plug a keyboard (and optionally a mouse)
# and turn the HTPC ON
# quickly hit F10 (NUC) or F12 to show up the boot menu
# boot UEFI:disk corresponding to GParted live USB
# GParted app should be opened so you can identify easily
# your internal hard drive (/dev/sda) and your USB stick ‘imgdisk’ (/dev/sdX)
# in our example:

internal hard drive (ssd): /dev/sda

imgdisk partition 1: /dev/sdb1

# QUIT GParted app

# open terminal with root permissions
# mount your usb imgdisk

```
$ mount /dev/sdX /media
```
```
$ cd /media
```
```
$ ls
```

# IMPORTANT: check the integrity of the image disk

```
$ sha1sum medialounge....img
```

# compare the result with the SHA1 line on website
# if this doesn’t match then your image disk is corrupted, you can’t go further until your img disk is clean
# clone from image disk to your internal disk (/dev/sda)
# ALL DATA IN INTERNAL HARD DRIVE/SSD WILL BE ERASED

$ sudo dd if=musiclounge.img of=/dev/sda bs=2048 status=progress

# then fix gpt backup header/table on the target disk

```
$ sudo sgdisk -e /dev/sda
```

# unmount /media

```
$ cd /
```
```
$ umount /media
```

# now launch GParted app to resize the root partition (3) of your internal disk (/dev/sda3)

# double-check and APPLY all changes

# expand partition 3 (minimum 16GB)

# shutdown your HTPC
# remove both GParted live usb and imgdisk usb drive

# congrats! You are now ready to enjoy your distribution

PART1: Cloning AMD64 UEFI Image Disk From Windows (Rufus)

April 26, 2023April 26, 2023 Linux Audio Team

# we assume you have a PC with Windows system with 7zip (or Winrar) and Rufus installed
# an USB Drive with GParted Live USB bootable

# more info on GParted website to create your a bootable Live system)

# and an USB3 To SATA adapter cable

# if you do not have the cable, follow the instructions of SOLUTION 2

WINDOWS PC

# download the distribution from our website/github and extract it with 7zip or Winrar

# IMPORTANT: check the integrity of the image disk
# and compare the result with the corresponding SHA256 line on website

# run powershell (i.e. Windows Terminal) and type:

Get-FileHash C:\path\to\imagedisk.img

# if this doesn’t match then your image disk is corrupted, you can’t go further until your img disk is clean
# connect your SSD (or 2.5″ Hard drive) to your PC with the Startech USB3 To SATA adapter

# then run Rufus and select the image disk, tick the “List USB Hard Drives” and select your SSD
# clone from image disk to your internal disk
#ALL DATA IN INTERNAL HARD DRIVE/SSD WILL BE ERASED

# After the cloning, close Rufus, disconnect the adapter cable from the PC and mount the SSD inside your Barebone PC/NUC

BAREBONE PC (HTPC)

# insert the the GParted Live USB, plug a keyboard (and optionally a mouse)
# and turn the HTPC ON
# quickly hit F10 (NUC) or F12 to show up the boot menu
# boot UEFI:disk corresponding to GParted live USB
# GParted app should be opened so you can identify easily
# your internal hard drive (/dev/sda)
# Fix the GPT backup header/table if GParted prompts to do so

# resize the root partition of your internal disk (/dev/sda3)

# double-check and APPLY all changes

# expand partition 3 (minimum 16GB)

# shutdown your HTPC
# remove both GParted live usb

# congrats! You are now ready to enjoy your distribution

expand partition with gparted

February 23, 2023April 23, 2023 Linux Audio Team

Expand Your Main Partition With GParted

# Armbian and Raspi OS come with a nice utility to expand your partition (read the Musiclounge installation for more info) but what about Debian/Ubuntu?
# for this distro you need to do it manually but don’t worry

# with the great GParted it’s very easy

# grab the gparted live iso, make a bootable sd card or usb stick to expand your hard drive
https://gparted.org/livecd.php

# so you already created your image disk of MusicLounge audiophile server for amd64 on hard drive, usb stick or SD card

# boot with GParted Live USB key and run GParted (the software should startup automatically)

# select on top-right menu your musiclounge device disk (here it’s /dev/sdc)

# in edition 2023 the root partition is the last.
# so it is very easy, unmount root partition and expand it

# may need to fix the GPT table backup due to the different size of the hard drive.

# if GPT partions table is corrupted, open terminal and fix gpt with

# assuming it is on /dev/sda disk

```
$ sudo sgdisk -e /dev/sda
```

# that’s it!
# your MusicLounge Audiophile Server distro is now ready

# however if your root partition is before the swap do the following

# right-click the main partition to unmount musiclounge device

# click the swap partition and right-click to select Resize/Move

# select Align To Cylinder and
# move the partition to the end (or put zero in free space following)
# then click Resize/Move button

# click the main partition and right-click to select Resize/Move

# resize the partition to the end
# then click Resize/Move button

# apply changes

# that’s it!
# your MusicLounge Audiophile Server distro is now ready

Cloning AMD64 UEFI Image Disk From Windows

February 23, 2023April 30, 2023 Linux Audio Team

# cloning large UEFI image disk (5GB+) from Windows to internal hard drive (or SSD) may cause of corrupt installation
# also due to GPT structure, cloning to another disk is not enough, you need to rewrite the GPT backup header/table on the last 33 sectors of your target disk
# finally you really need to resize the root partition to get enough space for using the distribution

# here are the instructions to make this from Windows and with GParted Live on Linux side.

SOLUTION 1 Requirements

This way is very easy but requires to remove the hard drive/SSD from the Barebone PC/NUC and a special USB3.0 to SATA adapter cable (ref. USB3S2SAT3CB from StartTech).

Windows PC with Rufus and 7-Zip (or Winrar) Installed
1 USB Drive with Bootable GParted Live

1 USB3 To SATA adapter cable

SOLUTION 1

SOLUTION 2 Requirements

Windows PC with Rufus and 7-Zip (or Winrar) Installed
1 USB drive for the image disk
1 USB Drive with Bootable GParted Live

SOLUTION 2

Upgrade MusicLounge Server Editon 2021 To Editon 2023

# Important Notice: The image disk of the 2023 edition for Raspberry PI 4, Odroid C4 and amd64 platform are available for download HERE.
#
# follow the instructions below to upgrade your edition 2021 of MusicLounge. The audiophile server must be already installed and operational.
#
# be sure your data partition is resized

# expanding your partition during the boot can take a while (depending the size of your SD Card) so be patient,

# at first boot you should see

Usage of /: 71% of 3.7G

# after expansion on 16GB SD Card

Usage of /: 19% of 14G

# for debian amd64 expand your hard drive if needed using gparted on live distro or from desktop PC is easy
# first move the swap sda2 to end and then resize sda1

I2S DAC Support

September 27, 2022February 13, 2023 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

CTRL+X to SAVE

Reboot and That’s It!

Now check if card number is 1 using aplay -l

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

overlay_profile=hifishield

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

May 14, 2003March 26, 2023 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

```
$ sudo apt update -y
```
```
$ 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

```
~# su - root
```
```
~# apt install sudo
```
```
~# usermod -aG sudo pi
```

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

```
$ su - root
```
```
$ 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

```
exit
```

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

```
$ sudo apt install openssh-server -y
```

# active service

```
$ sudo systemctl start ssh
```
```
$ 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

```
$ 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

```
$ sudo update-grub
```

that’s it!

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

```
$ 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:

```
$ aplay -l
```

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

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

# list devices to see if your DAC is recognized

```
$ aplay -l
