HiFi Setup

This audio rig is for audio enthusiast looking to step into the world of audiophile on a budget. This setup consists of four components: the music server (RasPi+LMS), the audio playback unit (RasPi+HiFiBerry), the amplifier (NAD D3020), and the speakers (Wharfedale Diamond 10). Currently, the entire setup can be put together for under USD 1,000.

Setting up the Lyrion Music Server (LMS)

Lyrion Music Server (LMS) (formerly Logitech Media Server) is open-source server software which controls a wide range of Squeezebox audio players including HiFiBerry. Lyrion can stream your local music collection, internet radio stations, and content from many streaming services (with and without subscriptions). In this section we will document the installation of LMS on a Raspberry Pi OS Lite.

INSTALLING RASPBERRY PI OS LITE

Download and start the Raspberry Pi imager.
Choose the OS type: Raspberry Pi OS Lite (64 bit)
Choose the target SD card.
From settings preconfigure avaialble options eg. ssh creds, WiFi creds, hostname, etc.. This is essential for headless install.
Login using PuTTy using the preconfigured SSH user and update OS and install essential eg. vim

INSTALLING UFW FIREWALL (OPTIONAL)

NOT NEEDED if unit is inside a firewall.

sudo apt install ufw
Before rebooting make sure you allow SSH: sudo ufw allow 22
Check the status sudo ufw status

MOUNTING EXTERNAL SSD

Find the block device name eg. /dev/sda using the command lsblk
Create a partition (not necessary but highly recommended) using fdisk:
- fdisk -l to list all partitions available.
- fdisk /dev/sda
- n for creating a partition. For creating one Linux partition use the defaults.
- p print the partition for checking.
- w write the partition to disk.
Now you can see the block device for the new partition eg. /dev/sda1 using lsblk
Create a ext4 partition: sudo mkfs.ext4 /dev/sda1
Find the UUID of the partition: blkid /dev/sda1
Create a mount point: sudo mkdir /media/wd220
Create a fstab entry in /etc/fstab:
- UUID=5abdf860-950b-40b8-8799-49f6ce70044c /media/wd220 ext4 defaults,auto,users,rw,nofail 0 0
- FIXME document the options.
sudo mount -a

CREATING A SAMBA SHARE

Could not get a Public share to work. Write permission error from Windows. After trying out lot of ways, following seem to work for a Private share.

Create the share directory: sudo mkdir /media/wd220/Music
Change owner, group and permission to the user that will be a samba user say smbuser:
- sudo chown smbuser /media/wd220/Music
- sudo chgrp users /media/wd220/Music
- sudo chmod 2775 /media/wd220/Music The 2 in the begining makes the folder sticky so users in the group “users” can write to the directory with their ownership.
Install samba : sudo apt-get install samba smb-client cifs-utils
Add the Windows group (eg. WORKGROUP) to the global option in /etc/samba/smb.conf
Add the share folder to /etc/samba/smb.conf:

[Music]
   comment = Public Music Folder
   path = /media/wd220/Music
   read only = no
   guest ok = no
   valid users = smbuser

sudo smbpasswd -a smbuser Add the user as a Samba user. You are going to use this credential when accessing the folder from Windows.
Allow the SMB ports 139,445 in the firewall (if ufw enabled):

LOGITECH MEDIA SERVER (LMS) on RaspberryPiOS

This section documents the steps in installing Logitech Media Server for organizing Music files. Also, this installation was done on the Raspberry Pi OS that is already running OpenMediaVault (OMV) . So all filesystems are managed through OMV.

Followed the LMS part of Harald Kreuzer’s Blog. NOTE There is section in the blog about disabling the swap to increase the longetivity of the SD card. Worth looking into it.

Important steps are listed below:

sudo apt-get update && sudo apt-get upgrade -y followed by sudo reboot
Install LMS Server:

sudo apt-get install libsox-fmt-all libflac-dev libfaad2 
sudo apt-get install libio-socket-ssl-perl 
sudo apt-get install libcrypt-openssl-bignum-perl 
sudo apt-get install libcrypt-openssl-random-perl 
sudo apt-get install libcrypt-openssl-rsa-perl 
wget https://downloads.slimdevices.com/LogitechMediaServer_v8.3.1/logitechmediaserver_8.3.1_arm.deb 
sudo dpkg -i logitechmediaserver_8.3.1_arm.deb

NOTE Check the latest LMS distro available.

sudo ufw allow 9000
The server will now be accessible at http://<IP>:9000/
- NOTE you do not need to create the logitech account. You can skipt.
FIXME Create the appropriate directory structure in OMV and configure that here.
- You can check these links (BegineersGuide, Survey, Organize4DJ-MP3Tags) to see some popular ways to organize folders for music.
- One popular choice is: /<library>/<artist>/<album>/<tracks>
- Organizing Classical Music is different (See BegineersGuideToClassical. A simple tagging (Tagged during ripping) reco from the guide:
  - the folder strategy I am using now is: /<lib>/<composer>/<CDalbum>/<tracks>
  - For Various artiests: /<lib>/<VariousArtist>/<CDalbum>/<tracks>
  - Tag reco:
    - Album tag for Work eg. “Beethoven Symphony no. 5 - Karajan”
    - Artist tag for Composer eg. “Beethoven”
    - Title tag for Movement eg. “Beethoven Symp 5 - 3- Allegro”
You can remove all unnecessary plugins.
It’s worth installing the material plugin which is a responsive plugin so the server will be accessible at https://<IP>:9000/material even from a mobile.

AWS CLI

Check this section for installing aws cli tools.
Note, download the ARM version instead of the x86 version:
- curl "https://awscli.amazonaws.com/awscli-exe-linux-aarch64.zip" -o "awscliv2.zip"

Setting crontab for syncing from AWS S3

00 03 * * 1 aws s3 sync --delete --profile srout s3://linode-vm01-bak /media/wd220/aws-S3/srout/linode-vm01-bak > /home/srout/logs/s3sync-linodevm01.log 2>&1

sudo ufw allow 139
sudo ufw allow 445

sudo systemctl restart smbd Restart the SMB daemon.
Now try accessing from Windows Win+R and entering \\[IP/hostname]/Music
