# ALSA Scarlett Gen 2/3 Control Panel Installation
## Prerequisites
Linux Kernel with the ALSA Scarlett2 Protocol Driver.
- Use at least version 5.14 for Scarlett Gen 3 support and bug fixes
for the Gen 2 support.
- For Clarett+ 8Pre support, you need 6.1.
- For the other Clarett USB and Clarett+ models, you need 6.7.
- For the level meters to work, you need 6.7.
If you don't have 6.7, you can get the driver from here and build it
for your current kernel:
https://github.com/geoffreybennett/scarlett-gen2/releases/tag/v6.5.11c1
## Enabling the Driver
As of Linux 6.7 the driver is enabled by default and you can skip this
section.
If you're running a kernel before 6.7, the driver needs to be enabled
at module load time with the `device_setup=1` option to
insmod/modprobe. Create a file /etc/modprobe.d/scarlett.conf
containing the appropriate line for your device:
Scarlett Gen 2:
- 6i6: `options snd_usb_audio vid=0x1235 pid=0x8203 device_setup=1`
- 18i8: `options snd_usb_audio vid=0x1235 pid=0x8204 device_setup=1`
- 18i20: `options snd_usb_audio vid=0x1235 pid=0x8201 device_setup=1`
Scarlett Gen 3:
- Solo: `options snd_usb_audio vid=0x1235 pid=0x8211 device_setup=1`
- 2i2: `options snd_usb_audio vid=0x1235 pid=0x8210 device_setup=1`
- 4i4: `options snd_usb_audio vid=0x1235 pid=0x8212 device_setup=1`
- 8i6: `options snd_usb_audio vid=0x1235 pid=0x8213 device_setup=1`
- 18i8: `options snd_usb_audio vid=0x1235 pid=0x8214 device_setup=1`
- 18i20: `options snd_usb_audio vid=0x1235 pid=0x8215 device_setup=1`
Clarett+:
- 8Pre: `options snd_usb_audio vid=0x1235 pid=0x820c device_setup=1`
Or you can use a sledgehammer:
```
options snd_usb_audio device_setup=1,1,1,1
```
to pass that option to the first 4 USB audio devices.
To see if the driver is present and enabled: `dmesg | grep -i -A 5 -B
5 focusrite` should display information like:
```
New USB device found, idVendor=1235, idProduct=8215, bcdDevice= 6.0b
Product: Scarlett 18i20 USB
Focusrite Scarlett Gen 2/3 Mixer Driver enabled pid=0x8215
```
If the driver is disabled you’ll see a message like:
```
Focusrite Scarlett Gen 2/3 Mixer Driver disabled; use options
snd_usb_audio vid=0x1235 pid=0x8215 device_setup=1 to enable and
report any issues to g@b4.vu",
```
## Building and Running
On Fedora, the packages `alsa-lib-devel` and `gtk4-devel` need to be
installed:
```
sudo dnf -y install alsa-lib-devel gtk4-devel
```
On Ubuntu 22.04:
```
sudo apt -y install git make gcc libgtk-4-dev libasound2-dev
```
To download from github:
```
git clone https://github.com/geoffreybennett/alsa-scarlett-gui
cd alsa-scarlett-gui
```
To build:
```
cd src
make -j4
```
To run:
```
./alsa-scarlett-gui
```
You can install it into `/usr/local` (binary, desktop file, and icon)
with:
```
sudo make install
```
And uninstall with:
```
sudo make uninstall
```
Continue on to reading [USAGE.md](USAGE.md) for usage information and
known issues.
## Flatpak
With Flatpak, in any distro:
```
flatpak-builder --user --install --force-clean flatpak-build \
vu.b4.alsa-scarlett-gui.yml
```
Be sure to use `flatpak-build` as the directory where the flatpak is
built or hence you risk bundling the artifacts when comitting!
If you get messages like these:
```
Failed to init: Unable to find sdk org.gnome.Sdk version 45
Failed to init: Unable to find runtime org.gnome.Platform version 45
```
Then install them:
```
flatpak install org.gnome.Sdk
flatpak install org.gnome.Platform
```
If you get:
```
Looking for matches…
error: No remote refs found for ‘org.gnome.Sdk’
```
Then:
```
flatpak remote-add --user --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
```

# ALSA Scarlett Gen 2/3 Control Panel (`alsa-scarlett-gui`)
`alsa-scarlett-gui` is a Gtk4 GUI for the ALSA controls presented by
the Linux kernel Focusrite Scarlett Gen 2/3 Mixer Driver.

Driver.
## About
<img src="src/img/alsa-scarlett-gui-logo.png" align="right">
The Focusrite Scarlett interfaces are class compliant USB audio
interfaces meaning that they work “out of the box” on Linux as audio
and MIDI interfaces (although on Gen 3 you need to disable MSD mode
first). However, the Gen 2 6i6+ and Gen 3 4i4+ interfaces have a bunch
of proprietary functionality that required a kernel driver to be
written specifically for those devices.
The Focusrite USB audio interfaces are class compliant meaning that
they work “out of the box” on Linux as audio and MIDI interfaces
(although on Gen 3/4 you need to disable MSD mode first for full
functionality). However, except for some of the smallest models, they
have a bunch of proprietary functionality that required a kernel
driver to be written specifically for those devices.
Linux kernel support (“ALSA Focusrite Scarlett Gen 2/3 Mixer Driver”)
for the proprietary functionality of Gen 2 devices was first added in
5.4 and Gen 3 devices in 5.14.
for the proprietary functionality was first added in:
- Scarlett Gen 2: Linux 5.4 (bugs fixed in Linux 5.14)
- Scarlett Gen 3: Linux 5.14
- Clarett+ 8Pre: Linux 6.1
- Clarett 2Pre/4Pre/8Pre USB, Clarett+ 2Pre/4Pre: Linux 6.7
Unfortunately, actually using this functionality was quite awful. The
existing applications like `alsamixer` and `qasmixer` become
completely user-hostile with the hundreds of controls presented for
the Gen 3 18i20. Even the smallest Gen 3 4i4 interface at last count
had 84 ALSA controls.

This program is Free Software, developed using my personal resources,

the driver or this control panel in any way. Thanks to Laurent

## Scarlett Gen 4 Support
Focusrite recently released 3 new "Generation 4" interfaces: Solo,
2i2, and 4i4. Thanks to all the Linux Musicians who donated so I could
purchase one of each Gen 4 interface: https://gofund.me/ae997781,
support for these is coming soon.
The overwhelming response to the GoFundMe also got the attention of
Focusrite. They offered to send me any devices that I didn't already
have, and also said that for any future product releases, they will do
their utmost to send me devices in advance.
## Vocaster Support
Vocaster One and Two support will be coming once I've completed the
Scarlett 4th Gen support.
