## Prerequisites
|
||||
|
||||
### Linux Kernel
|
||||
|
||||
You need to be running a Linux Kernel that has the ALSA Scarlett2
|
||||
Protocol Driver. Use `uname -r` to check what kernel version you are
|
||||
running.
|
||||
You need to be running a Linux Kernel that contains the appropriate
|
||||
driver for your interface. Use `uname -r` to check what kernel version
|
||||
you are running.
|
||||
|
||||
- For reasonable functionality of Scarlett 2nd and 3rd Gen and Clarett
|
||||
interfaces, you need at least Linux kernel version 6.7
|
||||
- For Scarlett 4th Gen support and firmware updates from Linux, you
|
||||
need at least 6.8
|
||||
- For Vocaster support, you’ll need to build an updated
|
||||
`snd-usb-audio` driver (or wait for 6.10)
|
||||
Check the following table to see which driver your interface uses and
|
||||
the first kernel version that the driver was included in:
|
||||
|
||||
If you’ve got a Vocaster, or if your distribution doesn’t include a
|
||||
recent-enough kernel for your interface, you can get the latest driver
|
||||
from here and build it for your current kernel:
|
||||

| Scarlett 1st Gen | 6i6, 8i6, 18i6, 18i8, 18i20 | Scarlett 1st Gen Mixer Driver | 3.19+ |

| Scarlett 2nd Gen | Solo, 2i2, 2i4 | N/A* | Any |

|
||||
\* The small 1st Gen and 2nd Gen models don’t have any proprietary
|
||||
software controls so they don’t need a driver beyond the standard ALSA
|
||||
USB Audio driver. This means that this application (alsa-scarlett-gui)
|
||||
is not needed, useful, or supported for these models.
|
||||
|
||||
#### Enabling the Driver
|
||||
If your distribution doesn’t include a recent-enough kernel for your
|
||||
interface, you can get the latest driver from here and build it for
|
||||
your current kernel if it's not too old (the Scarlett2 and FCP drivers
|
||||
are both maintained in the same tree here):
|
||||
https://github.com/geoffreybennett/linux-fcp/releases
|
||||
|
||||
As of Linux 6.7 the driver is enabled by default. Check the driver
|
||||
Kernel 6.7 and later have the Scarlett2 driver enabled by default. The
|
||||
Scarlett 1st Gen driver and the FCP drivers are always enabled.
|
||||
|
||||
#### Enabling the Scarlett2 Driver
|
||||
|
||||
Some kernels before 6.7 have an earlier version of the Scarlett2
|
||||
driver which is disabled by default. If this is you, check the driver
|
||||
status (after plugging your interface in) with this command:
|

### Firmware
|

|

As of Linux 6.8, firmware updates of all the supported interfaces can
|
||||
be done through Linux. This is mandatory for Scarlett 4th Gen and
|

Vocaster interfaces (unless you’ve already updated it using the

manufacturer’s software), and optional for Scarlett 2nd and 3rd Gen,

#### Scarlett2 Driver
|

|

As of Linux 6.8, firmware updates of all supported interfaces from the

2nd Gen onwards can be done through Linux. This is mandatory for
|
||||
Scarlett 4th Gen and Vocaster interfaces (unless you’ve already

interfaces.
|

|

Download the firmware from
|
||||
https://github.com/geoffreybennett/scarlett2-firmware and place it in
|

`/usr/lib/firmware/scarlett2` or use the RPM/deb package.
|

#### FCP Driver
|
||||
|
||||
Firmware updates for the big Scarlett 4th Gen interfaces is currently
|
||||
only possible through the CLI `fcp-tool` utility available in the
|
||||
[fcp-support](https://github.com/geoffreybennett/fcp-support). You
|
||||
need to install this package and update the firmware before
|
||||
alsa-scarlett-gui will work.
