+# FAQ for the Scarlett2 Mixer Driver and `alsa-scarlett-gui`
+
+## What is this?
+
+The Scarlett2 Protocol Driver (also known as the Scarlett2 Mixer
+Driver) is a part of the Linux kernel, enhancing the ALSA kernel
+driver with additional controls for Focusrite Scarlett and Clarett
+interfaces.
+
+To check your current version or for upgrade instructions, see the
+[Control Panel Installation Prerequisites — Linux
+Kernel](https://github.com/geoffreybennett/alsa-scarlett-gui/blob/master/INSTALL.md).
+
+`alsa-scarlett-gui` is an easy-to-use application to adjust those
+controls.
+
+## Do I need the driver for my Focusrite interface?
+
+In order to get audio working? No. Focusrite USB interfaces are
+“plug-and-play” — they are USB Audio Class Compliant, meaning they
+work out-of-the-box with the standard ALSA USB audio driver[^1].
+
+[^1]: To get full functionality on Scarlett 3rd/4th Gen interfaces,
+first deactivate MSD mode for by holding down the 48V button while
+powering it on (MSD is the virtual disk on the Scarlett that has a
+link to the Focusrite product registration page; until you turn that
+off not all features will be available).
+
+## What is the purpose of the driver then?
+
+This driver is for users who want more control over their interface.
+It allows for detailed manipulation of internal audio routing and
+settings specific to Scarlett devices, beyond the basic audio I/O
+functionality. Also, being able to monitor the audio levels seen by
+interface is really useful.
+
+## What interfaces are supported?
+
+- All Scarlett 2nd Gen interfaces with software controls (there are no
+  software controls on the 2nd Gen Solo and 2i2, so the mixer driver
+  is irrelevant).
+
+- All Scarlett 3rd Gen interfaces.
+
+- All Clarett USB and Clarett+ interfaces.
+
+## Where are the options to set the sample rate and buffer size?
+
+It’s important to note that the Scarlett2 driver and
+`alsa-scarlett-gui` have nothing to do with audio input/output to and
+from the device. This task is managed by the generic part of the ALSA
+USB soundcard driver.
+
+Audio settings like the sample rate and buffer size are chosen by the
+application which is using the soundcard. In most cases, that is a
+sound server such as PulseAudio, JACK, or PipeWire.
+
+Note that not all features are available at higher sample rates; refer
+to the user manual of your interface for more information.
+
+## Scarlett Gen 4? Vocaster?
+
+Support coming soon. Email me if you want to help test.
