ramroot 2.0.4
Please
make a full system update or update the package with
sudo

the problem after last system update should be fixed
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.

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 interface from a browser and NoMachine remoteDesktop in lxqt version
Audiolinux versions
Audiolinux headless versions are without graphical Desktop but a full set of menus. A little better in performance because of less memory used and less processes activeAudiolinux lxqt versions are with
graphical LXQt Desktop and a full set of menus
Audiolinux 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_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.

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
This menu will install rtpriority 2.6, necessary for the new applied changes
Option Audio Extra menu -> DIRETTA target installation/configuration -> Enable/Disable Diretta Target will load/remove new diretta_direct kernel module
