AudioLinux is based on realtime custom kernels and on the work of that part of linux community trying to achieve very low audio and processor latencies. The results are not audiophile subjective suggestions, but real and measurable. You can make a processor latency test yourself clicking on the oscilloscope test inside Realtime Priority folder on the Desktop. No magic hidden code, but only the magic of music. AudioLinux can be used in Audio Pro studio recording because of stability and freedom from glitches. With a powerful CPU is perfect for extreme upsampling (up to DSD 512 or PCM 768 kHz). What about the sound? Clean, transparent, the last veil is removed... and a quick and complete support that no one is giving in Linux. Your system will be fine-tuned for the absolute best performance.

Incredibly low processor latency (average 2-6 microseconds on fairly powerful processors)
Boot time 10/15 s
Maximize option for optimal audio system
Choice between two realtime process priority configurations (Standard or Extreme)
RTIRQ for automatic IRQ priority assignment
RTAPP for automatic audio priority
Compatible audio applications:
HQPlayer and HQPlayer embedded (with CUDA acceleration, if you install nvidia closed source drivers), HQPlayer Network Audio Daemon, MPD (with optional upmpdcli UPnP media renderer), Logitech Media Server + Squeezelite with C-3PO plugin, Kodi (XBMC), Jriver Media Center, Roon.
Audiolinux can be configured as headless server (also with HQPlayer embedded)

If you are a company that is selling a Streamer/Audio PC and you want a custom version of AudioLinux please contact us at

* From version headless 0.7 there are now 4 configuration menus:

--> For general support consult first the wiki at
--> If you have installed to internal drive, you should have also audiolinux on a USB stick, in case of operations that cannot be made from inside (boot problems, hard disk check, etc.)

* For audiolinux lxqt please look inside the directory "Start here" on the Desktop and read all the... read-me files.
You can also configure this version as headless selecting the appropriate default (see below
CHANGING BOOT DEFAULT). In this case you can minimize the system removing completely gvfs with
pacman -R gvfs gvfs-afc gvfs-nfs gvfs-smb
and eventually disabling NoMachine:
systemctl disable nxserver
--> Also in headless mode you can connect to lxqt desktop with NoMachine and return to headless with a logout, see section REMOTE CONNECTION


user, ssh, NoMachine: audiolinux
root, samba: audiolinux0

hqplayerd web interface:
user: audiolinux
password audiolinux (or audiolinux0)


* In audiolinux lxqt you can use pcmanfm-qt file explorer (click on the red icon on the bottom bar for root editing)

An easy method to work with files for edit, copy etc. is to use Midnight Commander. Type
for starting it

otherwise you can use nano
nano full-file-path
nano /etc/fstab


How to switch to root user:
and give the password audiolinux0
You can return to normal user with

For poweroff and reboot, you can use sudo in a user (not root) terminal:
sudo poweroff
sudo reboot

* In audiolinux lxqt you can use the usual shortcuts


* In audiolinux lxqt you can find special shortcuts in
/Start here/Expert/Ramroot/

It is recommended at least 16GB RAM for lxqt version (8 GB for AudioLinux headless)

To load the entire system at boot, type (as root)
ramroot -F enable
To disable ramroot
ramroot remove

--> if you are using Roon, please take into account that Roon database will take some space, please be sure that the drive and ram size are enough

When in ram mode you can use these commands (the first 2 as root):
ramsave --> save the system when in ram mode (otherwise all changes will be lost)
clean --> remove trash files, pacman and system cache
memorytest --> check memory speed

For system modification and system update we suggest however to boot in normal mode answering N to ramroot boot prompt. Modifications to the file /etc/fstab will be saved only in normal mode. For kernel update you must disable ramroot, see section

For reducing ramroot timeout default at boot, you can edit as root /usr/bin/ramroot and change
from 15 seconds to the value you want


* In audiolinux lxqt you can connect to graphical Desktop with NoMachine, if you install it in Windows, Linux, smartphone. With NoMachine remote Dektop you can start headless without graphical Desktop and access AudioLinux in a virtual Desktop identical to the default one. After your configuration is finished, you can switch back to headless with a simple logout.

From version 0.7
you can connect remotely with a browser at the address http://ipaddress:8500

You can access audiolinux headless from another computer with ssh:
ssh audiolinux@ip-address
If you want to use a file browser from another pc, you can use the protocol sftp
--> you can check the ip address for audiolinux with
ip addr show

--> From Windows you can use Putty
--> From Android JuiceSSH


* In audiolinux lxqt you can control your system from your smartphone or tablet with unified remote. See

To enable it, start lxqt configuration, go to Session settings/Autostart and enable "Unified Remote"
Unified remote is started with the command:
opt/urserver/urserver --daemon


* Audiolinux lxqt (from version 3.1.0) is using systemd network as headless version. If you want to switch to Network Manager you can type as root user:
systemctl disable
systemctl enable
and reboot
--> Using Network Manager is not recommended if you are using a license for hqplayer embedded

Audiolinux headless 0.5 has an automatic configuration that will permit to connect immediately after booting the first time.
However, for a more stable network configuration, follow the steps reported below.
---> if you have more than one card, add a second configuration file in /etc/systemd/network/

Look for your network name with
[audiolinux@archlinux ~]$ networkctl
 1 lo               loopback           carrier     unmanaged 
 2 enp3s0           ether              routable    configured

If your network is enp3s0 (yours will be most probably different) change as root /etc/systemd/network/ from






Delete (as root) /etc/systemd/network/ with
rm /etc/systemd/network/
and reboot

DHCP=yes will allow both ipv4 and ipv6
See wiki at

You can change from DHCP to a static address modifying the file /etc/systemd/network/ from






--> change Address, Gateway and DNS to your preferred values.

For WiFi, provided that your adapter is recognized by linux, a simple how-to can be found here
The relevant wiki section is here:
For wpa-supplicant:


* In audiolinux lxqt you can find some nice shortcuts for enabling/starting/disabling services inside Start here. MPD, LMS and squeezelite are already installed.

In audiolinux headless Roon and HQPlayer embedded are already installed.
The new Menu is already prepared for MPD, LMS and squeezelite. For installing these applications, go to the section OTHER AUDIO APPLICATIONS

With systemctl you can stop, start, restart or enable the services at boot. In the commands where there is not "--user" you must switch to root user (see above)


Starting and enabling hqplayerd:
systemctl --user start hqplayerd
systemctl --user enable hqplayerd

Starting and enabling Roon:
systemctl start roonserver
systemctl enable roonserver

Starting and enabling naa:
systemctl --user start networkaudio
systemctl --user enable networkaudio

You can stop or disable, changing start to stop and enable to disable.

If you need to enable samba:
systemctl enable smb
systemctl enable nmb

and reboot
Note: the directories /home/audiolinux/Downloads and /home/audiolinux/Music are already set as samba share

--> For showing enabled systemd services:
systemctl list-unit-files | grep enabled
For user services:
systemctl --user list-unit-files | grep enabled

Note 1: You can add some delay in starting hqplayerd or networkaudio. For this, go as root to
and take out the # in front of the line
# ExecStartPre=/bin/sleep 30
Default is 30 seconds, you can change this to a different value.

Note 2: When configuring hqplayerd at http://localhost:8088/auth or http://localhost:8088/config please be sure to select Scope --> user at top left, since audiolinux is using the user directory /home/audiolinux/.hqplayer/ for configuration files and license

Note 3: If you are using Roonbridge in more than one computer take into account that: "RoonBridge generates and writes out a unique id into its data directory on first run and uses that to identify itself to RoonServer. Clear out /var/roon on the second device (or hunt down and delete the RAATServer/Settings/unique_id file) and it will generate itself a new one next time it starts up."

Note 4 for lxqt version < 3.1.0: If hqplayerd is changing hardware signature after reboot, you must change network manager to systemd network. See NETWORK section


For updating a single application:
pacman -Sy (update the database)
pacman -S name-of-application
if this application is in AUR database (as HQPlayer, Roon, etc.)
pamac build name-of-application
Example for updating hqplayerd and roon:
pamac build hqplayer-embedded roonserver roonbridge

For updating the system (expert users)
pamac update

For system modification and system update we suggest to boot in normal mode answering N to ramroot boot prompt.


* In audiolinux lxqt mpd, logitechmediaserver and  squeezelite are already installed

Squeezelite + LMS installation:
pamac build logitechmediaserver-git squeezelite-git
Configuration file for squeezelite: /etc/squeezelite.conf
For listing available devices:
squeezelite -l

If you want to install the standard git version of Squeezelite, download the package from here and install it with
pacman -U squeezelite-git-1.9.0-1-x86_64.pkg.tar.xz
Take into account that the new configuration file will be /etc/squeezelite.conf and and that the systemd service can be started with
systemctl start squeezelite

From version 0.7 you have the option to install Squeezelite and LMS from update menu

MPD and UPnP installation:
pamac build mpd upmpdcli
Configuration file for MPD: /home/audiolinux/.mpdconf

Please note that these commands will install the application and many dependencies, so audiolinux size will increase and as a consequence boot time in ram mode.


* In audiolinux lxqt go to with Chromium, download the files and install with pacman -U followed by the names of the packages

From version 0.7 you can update kernel from audiolinux update menu

Installing new audiolinux realtime kernel.
Go to and download at least linux-rt-bfq-* and linux-rt-bfq-headers-*
After nstall the new kernel with pacman -U followed by the names of the packages.

*** If you are running in ram mode, reboot answering N at boot prompt to boot in normal mode.
If you cannot connect to a monitor/keyboard you must disable ramroot before updating the kernel:
1) DISABLE ramroot with
ramroot remove
2) Reboot
3) Install the new kernel
4) Reboot
5) Eventually re-enable it with
ramroot -F enable
6) Reboot


* In audiolinux lxqt you have 2 more options:
audiolinuxBFQcl (headless command line boot)
audiolinuxEXTREMEcl.conf and  audiolinuxEXTREME2cl.conf (headless command line boot, extreme mode)

For changing boot default you can edit as root the file
and change the line
default audiolinuxBFQ
default archlinux (standard archlinux kernel, if installed)
default audiolinux-fallback (realtime kernel bfq, if you have problems at boot because of missing drivers)
default audiolinux  (standard rt kernel, if installed)
default audiolinuxEXTREME (realtime kernel bfq with some parameters that prevent cpu sleep. High CPU temperature)
default audiolinuxEXTREME2 (as EXTREME but with an additional kernel parameter for exceptional cpu latency.  Very high CPU temperature)


* In audiolinux lxqt you can find some shortcuts in /Start here/Expert/Realtime Priority/ for changing Realtime priority

For testing:

For checking realtime status:

For checking audio cards parameters and irq assignements:

Manual realtime priority is controlled by rtirq and rtapp. In standard /etc/rtirq.conf priority is given to all usb devices:
but, if checking with rtstatus and rtcards shows that your dac is using xhci_hcd, you can change it to:

Suggested realtime configurations:

1) Standard

2) Extreme

Max possible priority is set system-wide at 98


* In audiolinux lxqt you can install all the nvidia packages with
pacman -S nvidia-dkms nvidia-settings nvidia-utils opencl-nvidia

--> This is necessary for enabling CUDA acceleration in HQPlayer, if you have a nvidia card.

You can install the nvidia proprietary drivers with
pacman -Sy
pacman -S nvidia-dkms nvidia-utils opencl-nvidia
After you should add the section "Device" to /etc/X11/xorg.conf.d/

Section "ServerFlags"
      Option "BlankTime" "0"
      Option "StandbyTime" "0"
      Option "SuspendTime" "0"
      Option "OffTime" "0"

Section "Device"
        Identifier "Nvidia Card"
        Driver "nvidia"
        VendorName "NVIDIA Corporation"
        Option "NoLogo" "true"
        Option "Coolbits" "4"

Optionally you could blacklist the open source driver "nouveau" creating the file /etc/modprobe.d/blacklist.conf with the following content:
blacklist nouveau

Understanding audiolinux 1 INSTALLATION

--> For audiolinux headless change

audiolinux_mini_150.img.gz to  audiolinux_360.img.gz    --> audiolinux headless (and lxqt from version 2.2.0) will boot only in UEFI mode

--> You cannot install audiolinux on a single partition but only to the full hard disk (audiolinux image has 2 partitions, UEFI fat32 and linux ext4)

To install audiolinux on external USB stick (32 GB) or internal Hard disk, if you already have linux installed in internal drive or  in external media (liveCD or liveUSB, for Ubuntu you can install this way and omit stage 2):
1) Boot from your linux installation and download the image
2) Open a terminal window and type
and then enter the password (audiolinux0 for audiolinux installation)
3) Verify that the image file is not corrupted with
4) Find the hard disk address by typing
fdisk -l
on Ubuntu: sudo fdisk -l
5) If, for example, the HD is /dev/sda, copy the image with
gunzip -c
audiolinux_mini_150.img.gz | dd of=/dev/sda
on Ubuntu: gunzip -c audiolinux_203.img.gz | sudo dd of=/dev/sda
(this will delete the hd, it is not necessary to format it previously)
6) Launch gparted and extend the ext4 partition until covering the remaining part of the hard disk (this will fix also GPT size errors. note that you will need more than the default size for Roon database)
--> If you will use ramroot later, leave some unallocated space on the hdd for an extra partition or add another drive, otherwise, if you copy the music files into audiolinux partition, the size will become too big for booting to ram.
7) Power off the PC, unplug previous external linux installation and boot from the new HD/USB stick.

--> If you have problems booting, consult our Booting Checklist

If you install from MAC, see the guide here
If you install from Windows, you can use
Rufus version 2.18 with option "dd" or Etcher
--> In this case you will miss step 6) of installation guide above. For a possible solution see
this guide case 1)  but installation with these applications is not recommended.

This is the official how-to, You can use also other methods that allow the cloning of an image with multiple partitions.

*  In lxqt version you can enable auto-mount enabling Mount in pcmanfm-qt file explorer --> Edit --> Preferences --> Volume

To auto-mount the hard disk at boot you need to edit the file /etc/fstab.
You can use a root teminal (type su and after give root password audiolinux0) with
nano /etc/fstab
You can also use pcmanfm-qt file explorer root (red icon on the bottom bar) and edit the file from there.
I suggest to mount in a subfolder of /media where there are some folders with the right permissions already set.
Don't mount outside of /media subfolders if you are using ramroot!
It is better to test the mount line before adding it to /etc/fstab. For example:
mount -t ntfs-3g UUID=
myuuid /media/samba -o uid=1000,gid=100,forceuid,forcegid
Please be careful. If /etc/fstab has a wrong line, the sytem could not boot.

To find LABEL or uuid type
in a terminal
Substitute mylabel, myuuid, servername, password etc. with your values.

Example for linux internal hard disk
LABEL=mylabel /media/linux1 ext4 nofail,noatime,rw 0 2
UUID=myuuid /media/linux1 ext4 nofail,noatime,rw 0 2

...For the full guide click here

In Audiolinux realtime priority is assigned by 2 services: rtirq for irq priority and rtapp for application priority.

1) RTIRQ configuration

The default configuration file is /etc/rtirq.conf
The important section is this one
In the default configuration it will give the defined priority to all usb devices. This is not a good choice if you have other USB equipment connected to your computer.
To check the realtime priorities you can use rtstatus...

Audiolinux for experts 1 NETWORK BRIDGE

If you need a Network Bridge it is advisable to use systemd network instead of NetworkManager, because "NetworkManager can create bridges, but currently will not auto-connect to them or slave/attached interfaces" cfr.:

Note: from version 0.4 of Audiolinux headless the step below is not necessary
First we must remove net.ifnames=0 from all the configurations files inside /boot/loader/entries/
You can use mc (Midnight Commander) or nano
nano /boot/loader/entries/audiolinuxBFQ.conf
After you must reboot

Now let's go to /etc/systemd/network/
cd /etc/systemd/network/
We remove the previous files, if any
rm /etc/systemd/network/*

You can check the names of network interfaces with:
ip addr show
In the examples that will follow we have 2 network interfaces, enp3s0 and enp4s0. Your names can be different.
--> In my test enp4s0 is connected to the router (and internet) and enp3s0 is connected directly from pc (with a normal ethernet cable) to a BeagleBone Black naa running archlinuxarm

...For the full guide click here 

Roon Database can be huge.
This how-to can be applied in these cases:
1) Drive space is insufficient because you did not resize the ext4 partition after installation.
2) Ram size is not enough for booting in ram mode

...For the full guide click here
You can use Audiolinux for audio in the following combinations:

1) HQPlayer Desktop
2) Roon (headless)
3) Roon wth HQPlayer Desktop upsampling
4) Roon with HQPlayer embedded (headless)
5) Jriver with HQPlayer embedded
6) HQPDcontrol or BubbleUPnP or Mconnect on Android
with HQPlayer embedded (headless)
7) Mpd directly to Alsa or with Jack. In the first case sox PCM upsampling available
8) Logitech Media Server (LMS)
with C-3PO plugin and squeezelite.  PCM and DSD upsampling possible with many different filters (same as in Daphile, headless)
9) Jriver Media Center
10) Kodi media center

Roon with HQPlayer

Tidal music streaming is already integrated in Roon, BubbleUPnP, LMS and Mconnect. Qobuz is available on
BubbleUPnP, LMS and Mconnect. Spotify and Qobuz applications already installed (upsampling not possible).

With NoMachine remote Dektop you can start headless without graphical Desktop and access AudioLinux from smartphone or PC in a virtual Desktop identical to the default one. After your configuration is finished, you can switch back to headless with a simple logout.

AudioLinux processor latency test

We have made some tests of the real performance of AudioLinux.
You can make this test yourself clicking on the the oscilloscope test inside Realtime priority folder on the Desktop

1) Realtime test in AudioLinux with "hackbench -l 10000" and "cyclictest -t1 -n -p99 -i100 -o10 -v | oscilloscope -s1000 >/dev/null" with Intel i7-4770
Results upsampling with HQPlayer at the same time are not different!

Latest news

14/10/2019 IMPORTANT notice about update:
The updating in Audiolinux is done with
1) Audiolinux menu
2) Kernel. This is compiled by audiolinux with some changes if necessary (Note: A full system update could be necessary)
3) System update, not controlled by Audiolinux. This is normal Archlinux update.
A normal user does not need to make a system update. Audiolinux menu update is enough
Audiolinux will release a new version every 2 months with full package update, if the user want to reinstall an updated OS.
Single packages like HQPlayer, Roon and some other can be updated in Console without problems with the command
yaourt -Sy package-name
(with menu 126
pamac build package-name

Taking into consideration what is reported above, the last system update from version 1.5.0 is problematic for normal users. ...And also kernel update will not work correctly without a system update.

This is a normal occurrence in linux "rolling release" like Audionlinux/Archlinux, it is not relative to a bug in Audiolinux scripts.

Linux expert users could fix this, other should wait Audiolinux version 2.0 coming the 1st November

11/10/2019 New menu 126 needs a manual intervention, see
03/10/2019 New kernel RT BFQ 5.2.17 with rt9 realtime patch is out now
02/10/2019 Audiolinux 2.0 is coming 1st November with an increased price (not too much...) Until 30 October there is a SPECIAL OFFER: 1) You will have the possibility of buying at the old price of 49 $ for the first subscription 2) All users with a subscription will have to pay 25 $ for downloading Audiolinux 2.0, but before 30 October this payment will add a year to the subscription. For example if you have already bought it (or added extra year) in March your new subscription will stop in March 2021! 3) It is also possible to change from yearly to unlimited time support paying the difference of only 50 $ -> Note that all passwords will be reset from 1st November to a different system and next menu updates will be also password protected. If in doubt contact support!
02/10/2019 New menu version 125 with 1) Switch from yaourt to a special version of pamac for install/update, since yaourt is not developed any more 2) Some fixes to kernel installation script 3) From next big menu update (see news about Audiolinux 2.0) the menu update will be password-protected
14/09/2019 New update version 0.7 for Audiolinux Raspberry Pi3
04/09/2019 To avoid problems upgrading from kernel 4.19.x to 5.2.x, I suggest, when updating the kernel, to go to Audiolinux update menu and 1) System update (before was update all other packages) 2) Roon update (this is because roon is distributing the linux package without build number) 3) Update kernel 4) Select Clean on the main menu 5) Reboot

This way you can set to Extreme only selected cores and leave the other in standard mode. This method will disable the other one.
