Improved Realtime and Isolated Cores options in System menu
Since an IRQ could change after a reboot now you must give the
'address' of the device, for example xhci-hcd:usb1, 02:00.0, end0
etc.
Network IRQ configuration is now integrated with option 3)
Configure IRQ priority, systemd service rtnet and
/etc/rtpriority/rtnet.conf have been removed
Because of this you must re-configure realtime priority and
Isolated cores if enabled
Remember that you may need to reboot and wait at least 1 min. to
apply a new realtime/Isolated cores configuration

16/10/2025
Released kernel 6.17.3 for Audiolinux Classic, V3, V4
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. 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 DSD1024 or PCM 1536 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.
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_v3_750.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_v3_750.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.
You can
use Audiolinux for audio in the following combinations (but you
can install all applications available for linux, since you will
have full access to the OS)
1) HQPlayer
embedded controlled by HQPlayer client or Jriver or HQPDcontrol, BubbleUPnP,
Mconnect on smartphone/tablet
2) HQPlayer Desktop (lxqt version)
3) Roon
4) Roon wth HQPlayer Desktop or HQPlayer embedded
7) MPD controlled by
Cantata or many other control points on smartphone/tablet if
you enable UPnP for MPD
8) Logitech Media Server (LMS) and Squeezelite. Many control points on smartphone/tablet
available
9) Jriver
Media Center (lxqt version only)
10) Spotify
with the audio sevice raspotify, controlled by
official
Spotify on smartphone/tablet/PC
11)
NEW! Audirvana Studio or Origin controlled by remote Audirvana
app
Tidal and Qobuz music streaming services are already integrated in
HQPlayer client, Roon, LMS, Audirvana, BubbleUPnP and
Mconnect.

We
have made some tests of the real performance of AudioLinux.
You can make a similar test yourself selecting Realtime test in
Audiolinux Status menu.
