What is the AV Linux MX Edition (AVL-MXE) distribution, and how do you download, install, and configure it?

What is AV Linux MXE?

AV Linux MX Edition (AVL-MXE)is a Linux distribution specifically designed for multimedia content creation—particularly music production, audio recording, video editing, streaming, and graphics work.

It is essentially a specialized MX Linux/Debian-based system with AV Linux's multimedia customizations rather than a completely independent Linux family. The project describes the relationship as MX Linux providing the underlying system and AV Linux providing the multimedia focus, customizations, and kernels. Sstudylib.net+1

Its intended users include:

• Musicians and recording engineers

• ️ DAW users working with Ardour and other audio software

• MIDI and virtual-instrument users

• Video editors and content creators

• Streamers

• Graphic designers

• ‍ Users who need a Linux workstation already prepared for multimedia work

AV Linux has traditionally included applications such as Ardour, Kdenlive, OBS Studio, Blender, GIMP, Inkscape, and other multimedia tools. It also provides specialized low-latency/realtime kernel options and audio infrastructure intended for production work. Sstudylib.net

One important point: AV Linux MXE is not simply "MX Linux with some applications installed." It changes parts of the system specifically for multimedia—for example, kernel and audio configuration, realtime/low-latency behavior, and specialized repositories and packages. Sstudylib.net

1. Check your hardware first

AV Linux is intended to run directly on physical hardware. Older AVL-MXE documentation specifically cautions against using it in VirtualBox/VMware-style virtual machines, because virtualization can defeat some of the low-latency audio benefits. Sstudylib.net+1

For a serious audio workstation, I'd particularly check:

• 64-bit Intel/AMD processor

• At least 8 GB RAM; 16 GB+ is preferable for large projects

• SSD

• Adequate disk space for audio/video projects

• USB/Thunderbolt audio interface if you're doing recording

• GPU compatibility, especially if you have NVIDIA/AMD hardware

The graphics-driver situation deserves attention because the realtime kernel configuration has historically had restrictions concerning some third-party graphics drivers. Sstudylib.net

2. Download AV Linux

The project recommends obtaining the ISO from the official AV Linux website/mirrors, rather than random ISO-hosting sites. The AV Linux manual specifically recommends downloading from its official mirrors and verifying the accompanying checksums. Sstudylib.net

Official AV Linux website

The current AV Linux line is AV Linux MX Edition 25.x; Linux Audio's current project information lists AVL-MXe 25.2 "Ease", released May 30, 2026. WWiki Linux Audio

Download the appropriate 64-bit ISO for your machine.

You'll generally obtain something like:

AVL-MXE-...-x86_64.iso

along with checksum files.

---

3. Verify the ISO

Don't skip this step, particularly when installing an operating system.

Suppose the downloaded file is:

AVL-MXE-25.2-x86_64.iso

You can calculate its SHA-512 checksum with:

sha512sum AVL-MXE-25.2-x86_64.iso

Compare the result with the SHA-512 value supplied alongside the ISO.

You can also calculate MD5 if the release provides an MD5 checksum:

md5sum AVL-MXE-25.2-x86_64.iso

The AVL-MXE documentation specifically recommends checking the supplied MD5/SHA checksums before using the ISO. Sstudylib.net+1

---

4. Create a bootable USB

You'll need a USB flash drive—the process will erase the drive.

On another Linux machine, you can use a graphical tool such as Balena Etcher or GNOME Disks.

With dd, you can do it from the command line, but be extremely careful to select the correct device:

lsblk

Suppose the USB is /dev/sdb. Then:

sudo dd if=AVL-MXE-25.2-x86_64.iso of=/dev/sdb bs=4M status=progress oflag=sync

Do not use /dev/sdb1 here if /dev/sdb is the USB device—the ISO is written to the whole device.

Then:

sync

---

5. Boot the AV Linux Live system

Insert the USB into the target computer and reboot.

Open the computer's boot menu—often using a key such as:

F12
F11
Esc

The exact key depends on the manufacturer.

Select the USB drive.

AV Linux can be run as a Live system, allowing you to test hardware before installing. This is particularly useful for an audio workstation because you can check:

• Sound output

• Audio interface

• MIDI devices

• Wi-Fi

• Graphics

• Displays

• USB devices

• Basic performance

The AV Linux manual specifically documents using the ISO as a Live environment before installation. Sstudylib.net

---

6. Install AV Linux

Once you've booted into the Live desktop, launch the MX Installer.

The general installation procedure is similar to MX Linux because AVL-MXE uses MX's installation infrastructure. The AVL-MXE documentation describes the MX Installer as one of the major advantages of the MX-based design. Sstudylib.net

You'll be asked for things such as:

1. Installation disk

2. Partitioning method

3. User name

4. Computer name

5. Password

6. Bootloader configuration

7. Time zone/locale

If using the whole disk

For a dedicated AV Linux workstation, the simplest configuration is usually:

EFI System Partition
        ↓
/
        ↓
swap (optional)

Letting the installer automatically partition the disk is generally easiest for a dedicated machine.

Dual boot

If you're keeping Windows or another Linux distribution, do not select an option that erases the entire disk.

Back up important data first and carefully verify which partitions belong to which operating system.

---

7. Reboot into the installed system

When installation finishes:

Reboot

Remove the USB when prompted.

You should then boot into the installed AV Linux system.

---

8. Update the system

Once you've logged in, update the system.

You can use the graphical MX Updater, or from a terminal:

sudo apt update
sudo apt upgrade

Then reboot if the update installed a new kernel or other system components:

sudo reboot

MX Linux's documentation confirms that its normal update mechanism is based on APT and that MX Updater provides a graphical/system-tray way of handling updates. MMX Linux

---

9. Run the AVL-MXE Assistant

One of the important AV Linux-specific utilities is the AVL-MXE Assistant.

It's designed to expose configuration options that are particularly useful for a multimedia workstation.

The exact options vary between releases, but this is where you should look for AV Linux-specific configuration rather than blindly modifying system configuration files yourself.

In particular, investigate:

Dual boot

If you're keeping Windows or another Linux distribution, do not select an option that erases the entire disk.

---

7. Reboot into the installed system

Reboot

You should then boot into the installed AV Linux system.

---

8. Update the system

You can use the graphical MX Updater, or from a terminal:

sudo apt update
sudo apt upgrade

Then reboot if the update installed a new kernel or other system components:

sudo reboot

---

9. Run the AVL-MXE Assistant

It's designed to expose configuration options that are particularly useful for a multimedia workstation.

The exact options vary between releases, but this is where you should look for AV Linux-specific configuration rather than blindly modifying system configuration files yourself.

In particular, investigate:

• Kernel selection

• Performance configuration

• Audio configuration

• CPU governor

• Demo/commercial software options

• Other AV Linux-specific system tweaks

AVL-MXE has historically configured the CPU governor for performance and included realtime/low-latency tuning intended for audio production. Sstudylib.net

---

10. Configure the audio system

This is probably the most important configuration step if you're installing AV Linux for music production.

Linux audio can involve several layers:

Audio application
       ↓
JACK / PipeWire / PulseAudio
       ↓
ALSA
       ↓
Audio hardware

Historically, AVL-MXE has made extensive use of ALSA + JACK + PulseAudio integration, with JACK providing low-latency audio routing between applications and hardware. Sstudylib.net

Your audio interface should appear in the available audio devices.

You can inspect ALSA devices with:

aplay -l

and recording devices with:

arecord -l

For MIDI:

aconnect -l

---

11. Configure JACK/QjackCtl when needed

If you're using JACK-based applications, open QjackCtl.

Typical settings include:

Interface:      your audio interface
Sample Rate:    48000 Hz
Frames/Period:  128
Periods/Buffer: 2

These are starting points, not universal requirements.

For example:

Low-latency recording

48 kHz
128 frames
2 periods

can give relatively low latency.

Heavy projects

You may need:

48 kHz
256 frames
2 periods

or even:

512 frames

Increasing the buffer generally reduces the chance of xruns/dropouts but increases latency.

So don't simply choose the smallest buffer available.

---

12. Test for xruns

An xrun occurs when the audio system cannot process audio quickly enough, resulting in a dropout, click, or pop.

Start with a conservative buffer:

256 samples

Then gradually lower it:

256 → 128 → 64

while monitoring stability.

For recording vocals or instruments, low latency is valuable.

For mixing a very large project, stability may be more important than extremely low latency.

---

13. Configure your DAW

AV Linux is particularly useful because much of the multimedia software is already installed.

For example, Ardour can be configured to use your audio interface and JACK/audio subsystem.

A typical workflow is:

Audio interface
       ↓
     ALSA
       ↓
JACK / audio server
       ↓
    Ardour
       ↓
Plugins / instruments

You can then connect:

• Microphones

• Instruments

• MIDI controllers

• Software synthesizers

• Effects

• Monitors/headphones

---

14. MIDI configuration

Connect your MIDI keyboard/controller and check:

aconnect -l

You should see MIDI clients/devices.

You can then use your audio application's MIDI configuration to connect the controller to:

MIDI keyboard
      ↓
DAW
      ↓
Software instrument
      ↓
Audio output

For music production, this is one of the areas where AV Linux's preconfigured multimedia environment can save considerable setup time.

---

15. Install additional software

Because AV Linux is based on MX Linux/Debian, it uses the Debian package ecosystem and APT.

For example:

sudo apt update
sudo apt install git

You can also use MX's graphical package tools. MX Package Installer provides access to Debian/MX packages and, depending on configuration, Flatpaks and other package sources. MMX Linux

For third-party software, however, be cautious about blindly adding repositories. AV Linux already integrates specialized multimedia repositories, and mixing arbitrary Debian/Ubuntu repositories can create dependency problems.

In particular, don't treat Ubuntu PPAs as interchangeable with Debian/MX repositories.

---

16. Graphics drivers

This is an area where you should check your hardware before changing kernels.

AV Linux has provided different kernel choices, including realtime and low-latency configurations. The project documentation notes that certain default realtime kernels have limitations with third-party AMD/NVIDIA graphics drivers, while alternative low-latency kernels can provide better driver compatibility. Sstudylib.net

So if you have an NVIDIA GPU, for example, don't immediately install a proprietary driver without checking which AV Linux kernel you're running.

You can see your current kernel with:

uname -r

and inspect the GPU with:

lspci | grep -Ei 'vga|3d|display'

---

17. A sensible first-day configuration

After installation, I'd use this sequence:

# Update
sudo apt update
sudo apt upgrade

# Check kernel
uname -r

# Check hardware
lspci
lsusb

# Check audio
aplay -l

# Check recording devices
arecord -l

# Check MIDI
aconnect -l

Then:

1. Run AVL-MXE Assistant.

2. Configure your network.

3. Configure your display/GPU if necessary.

4. Connect the audio interface.

5. Confirm ALSA sees it.

6. Configure JACK/audio routing.

7. Open Ardour or your preferred DAW.

8. Test recording/playback.

9. Test MIDI.

10. Gradually reduce the audio buffer until you find a stable latency.

The important difference from ordinary Linux

With a conventional Debian/MX installation, you might have to build your multimedia environment yourself:

Linux
 ├── audio drivers
 ├── low-latency configuration
 ├── JACK/PipeWire configuration
 ├── DAW
 ├── plugins
 ├── MIDI tools
 └── video applications

AVL-MXE aims to provide much of that environment already configured:

       ├── Audio production
       ├── MIDI
       ├── Video editing
       ├── Streaming
       └── Graphics

That's its primary purpose: it is a ready-made multimedia workstation rather than a generic desktop distribution.

One caveat is important: the exact desktop, kernel, audio stack, included applications, and installation screens have changed between AVL-MXE generations. Therefore, use the manual corresponding to the ISO you're actually installing rather than following an older tutorial verbatim. The current project information identifies the 25.x series, while many online AVL-MXE tutorials still describe 21.x/23.x releases. Sstudylib.net+1
