14/03/2025 Released
new versions 7.1.0 of Audiolinux headless and 9.1.0 of
Audiolinux lxqt
The great
advantage is that now the service checking every minute if the
application is assigned to the right group of cores is no more
necessary
You must have a kernel with cgroup v2 enabled
(Users of Ravenna daemon and kernel module should update driver with the option in Audio extra menu to fix compatibility with kernel 6.12)
-> You must re-configure isolated cores with the option in System menu
You must reboot after each change in isolated cores configuration
NEW realtime priority framework using systemd CPUSchedulingPriority
The great advantage is that now the rtapp service checking every minute if an application process has the right priority is no more necessary
rtapp will start however if the application does not accept systemd priority, but only for that specific application
-> You must re-configure realtime priority with the option in System menu
You must restart your active audio services or reboot after the update and after each priority change

Audiolinux V4 released!
You can buy a V4 upgrade or the new
Audiolinux V4 in Audiolinux shop
All other images will NOT be
discontinued since avx512 extension set is available only on
a limited number of CPU
The price for upgrade is 50$*
Audiolinux V4 can be installed only if you have a CPU supporting avx512 extension, for example all Ryzen 7000 series, Intel rocketlake, Intel i3-1115G4, Intel i7-1165G7 etc.

Why
should you buy Audiolinux?
1) Audiolinux kernel with the
realtime patch will give audio applications a very high
priority with record CPU latency that can arrive at less
than 1 microsecond average on some systems2) Audiolinux V3/V4 kernels are compiled with x86_64_v3/ x86_64_v4 architecture, LTO FULL, 2000 Hz frequency and many patches including Audiolinux ones for a performance uplift from 10% to 36%!
Moreover pre-compiled optimized kernels are available for many architectures. If your CPU is not on the list you can ask support for a new optimized kernel that after will be updated regularly or you can compile the kernel automatically yourself
3) In V3/V4 versions applications and libraries are compiled with x86_64_v3/x86_64_v4 architecture
4) The proprietary application RTPRIORITY can assign specific realtime priority to your audiocard, audio application and network (rtirqs, rtapp, rtnet)
5) With proprietary application PPOWER you can choose and configure your CPU governor driver: acpi, intel pstate, amd pstate or amd pstate epp
6) A menu with more than 120 options with which even a system without a graphical desktop is easy to use
7) With ramroot option you can load the entire system to RAM for a record reactivity and general performance. This way you can run a system without drives
8) Full access to root will allow to install all applications available on linux and apply special configurations
9) Fast email support and remote Desktop support with AnyDesk if necessary
10) You can access Audiolinux from another PC with ssh/sftp, Web interfaces from a browser and NoMachine remoteDesktop in lxqt version
Audiolinux versions
Audiolinux classic headless is without graphical Desktop but a full set of menus. A little better in performance because of less memory used and less processes activeAudiolinux classic lxqt is with
graphical LXQt Desktop and all audio applications already
installed and tested. Audiolinux menus are included
Audiolinux headless and LXQt V3/V4
are completely rebuild OS with most applications and libraries
compiled with x86_64_v3 or x86_64_v4 and LTO with kernel optimized
for your specific CPU

MINI GUIDE
(clik on
images for full size display)
Main menu
INSTALLATION
--> 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). The target drive will be deleted. Recommended minimum size is 32 GB.
We recommend to install Audiolinux first to USB stick and after copy the installation to internal drive with the option "COPY/BACKUP current installation to another drive" in System menu. Keep this USB installation, it will be useful if you want to install to a second PC or for emergency fix.
LINUX
To install audiolinux on external USB stick or internal Hard Disk, if you already have linux installed (-> change name to your version file name):
1) Boot from your linux installation and download the image
2) Verify that the image file is not corrupted with
sha256sum audiolinux_mini_700.img.gz
3) Find the hard disk address by typing
sudo fdisk -l
4) If, for example, the HD is /dev/sda, copy the image with
gunzip -c audiolinux_mini_700.img.gz | sudo dd of=/dev/sda bs=1M status=progress
(this will delete the hd, it is not necessary to format it previously)
5) 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 plan to 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.
6) Power off the PC, unplug previous external linux installation and boot from the new HD/USB stick.
WINDOWS
If you install from Windows, you can use Rufus version 2.18 with option "dd"
MAC
If you install from MAC, see the guide here or you can use Etcher
HOW TO RESIZE AUDIOLINUX PARTITION
a) If you have Audiolinux LXQt: make a second installation on a USB stick, boot from the new installation and extend the ext4 partition on the old installation with gparted (easy, because the application has a GUI)
b) If you don't have Audiolinux LXQt: enable ramroot, reboot, select the option resize in system menu.
If you want to switch back to normal mode: reboot answering N to ramroot boot prompt at the beginning of boot, disable ramroot, reboot
--> If you have problems booting, consult our Booting Checklist
This is the official how-to, You can use also other methods that allow the cloning of an image with multiple partitions.
