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
# Odroid C4 with Armbian

$ sudo systemctl enable armbian-resize-filesystem

```
$ sudo reboot
```

# Raspberry PI 4 with RaspPI OS, simply run raspi-config and select Advanced Options > Expand Filesystem and reboot

```
$ sudo raspi-config
```

# 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
# click this link to read the tutorial to expand your disk with GParted

# First, ensure your system is up-to-date in it’s current release.

I2S DAC Support

September 27, 2022July 30, 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

DAC+ ADC Pro

dtoverlay=hifiberry-dacplusadcpro

Digi+

dtoverlay=hifiberry-digi

Digi+ Pro

dtoverlay=hifiberry-digi-pro

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 (C2) or overlay_hifishield2 (C4) and uses that section by the overlay_profile variable.

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

For C4 Only:

; Device Tree Overlay
overlay_resize=16384
overlay_profile=hifishield2
overlays="spi0 i2c0 i2c1 uart0"
 
[overlay_custom]
overlays="i2c0 i2c1"
 
[overlay_hktft32]
overlays="hktft32"
 
[overlay_hktft35]
overlays="hktft35"
 
[overlay_hifishield2]
overlays="hifishield2"

For C2 only:

; Device Tree Overlay
overlay_resize=16384
overlay_profile=hifishield
overlays="spi0 i2c0 i2c1 uart0"
 
[overlay_custom]
overlays="i2c0 i2c1"

Reboot and That’s It!

TROUBLESHOOTING: Static IP

May 14, 2003March 9, 2023 Linux Audio Team

# TS7

# Static IP not working
# assign IP to eth0 interface

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

```
$  ip link show
```

# ON RASPBERRY PI

1: lo:  mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000

2: eth0:  mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000

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: lo:  mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000

2: enp3s0:  mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000

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

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

```
$ sudo systemctl status mpd

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

# 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:

```
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:

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

TIDAL Connect Installation

May 12, 2003March 9, 2023 Linux Audio Team

# OPTIONAL: install Tidal Connect For Raspberry PI 4 only,

# for amd64 and odroid platform use an upnp client with Tidal plugin (see upnp renderer tutorial for more info)

# using your DAC to listen music from Tidal

Tidal Connect is a service similar to Spotify Connect. Using the Tidal app to play a song you can easily click the device selector icon (top right) to select the Musiclounge Streamer audio server.

We are going to install it on MusicLounge Audio Server for Raspberry PI 4 as Tidal connect linux binary seems to be only available on arm 32bit (Raspberry PI). This installation is based on https://github.com/shawa github repo.

# if install pkg ends with error:
# “Failed to start The PHP 7.3 FastCGI Process Manager”
# type the cmd below to create the missing directory:

```
$ sudo mkdir /var/run/php
```

# add stretch repo to sources list
# we need to temporary add it to install old libavformat.so.57

# add line:

deb http://archive.raspbian.org/raspbian stretch main

```
$ sudo nano /etc/apt/sources.list
```

CTRL+X and y to save

# update pkgs list

```
$ sudo apt update
```

# install dependencies

$ sudo apt install -y libavformat57 libportaudio2* libflac++6v5*

# edit again /etc/apt/sources.list to disable (place # to comment) debian stretch repo after the installation of the libs

```
$ sudo nano /etc/apt/sources.list
```

#deb http://archive.raspbian.org/raspbian stretch main

# CTRL+X and Y to Save

# install other dependencies

$ sudo curl -k -O -L http://security.debian.org/debian-security/pool/updates/main/o/openssl/libssl1.0.0_1.0.1t-1+deb8u12_armhf.deb

# create working folder

```
$ sudo mkdir /usr/ifi

# enter directory

```
$ cd /usr/ifi
```

# clone git repo inside the directory

$ sudo git clone https://github.com/shawaj/ifi-tidal-release

# fix file permissions

$ sudo chmod +x /usr/ifi/ifi-tidal-release/bin/tidal_connect_application

$ sudo chmod +x /usr/ifi/ifi-tidal-release/pa_devs/run.sh

# deploy tidal service

$ sudo ./ifi-tidal-release/file-deploy.sh

# get your device name

```
$ aplay -l
```

# in this example the USB DAC detected is a Topping D90 MQA on card 1

card 0: Headphones [bcm2835 Headphones], device 0: bcm2835 Headphones [bcm2835 Headphones]
  Subdevices: 8/8
  Subdevice #0: subdevice #0
  Subdevice #1: subdevice #1
 ...
card 1: MQA [D90 MQA], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

# edit the tidal connect service to update your device name

# change parameter -f and –model-name with Musiclounge Streamer
# if your DAC supports MQA set parameter –codec-mqa and –enable-mqa-passthrough to true
# and change (or add) parameter –playback-device with your USB DAC name followed by “: USB Audio (hw:x,0)”
# x corresponding to the card number: (hw:1,0) for card 1
