# ALSA Scarlett Gen 2/3 Control Panel Installation
|
||
|
||
## Prerequisites
|
||
|
||
Linux Kernel with the ALSA Scarlett Gen 2/3 mixer 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, and for Clarett 8Pre
|
||
USB see
|
||
https://github.com/geoffreybennett/scarlett-gen2/commits/scarlett-gen3
|
||
for kernel patches. Clarett+ 4Pre is coming soon. For support for
|
||
other Clarett devices, please contact me.
|
||
|
||
As of Linux 6.5, the driver is still disabled by default and 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 USB:
|
||
|
||
- 8Pre: `options snd_usb_audio vid=0x1235 pid=0x8208 device_setup=1`
|
||
|
||
Clarett+:
|
||
|
||
- 4Pre: `options snd_usb_audio vid=0x1235 pid=0x820b device_setup=1`
|
||
- 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)
|
||
