[Resolved] Focusrite Scarlet 2i2 Gen 2 Audio Interface Driver Install

I have it working but am noticing an annoying amount of playback latency.
From the research I have done it seems like this is an issue because the proper drivers for the device may not be installed.
I don't think Focusrite actually makes a dedicated linux driver for this thing.

Any advice?

You have the driver, chances are focusrite simply violates some specs in some form, or reacts allergic to certain ways of talking to the device.  FWIW they are notorious for issues here and you likely have to play a bit with some of the default knobs used by the tools that query audio devices

Are you using a sound daemon? Which? If pipewire, look at e.g. https://gitlab.freedesktop.org/pipewire … te_1847025 for forcing 441kHz probes for example.

If that didn't help get more specific. What "latency" exactly? When reproducing the issue what's your output of

sudo dmesg | grep snd
aplay -lL
pactl list sinks
pactl list sink-inputs
pw-top

I don't actually remember if I am using Pipewire or Pulse Audio. I *think* it is pipewire.
I am not sure how to mess with device settings actually. My 1st thought was to mess with buffer size but am not certain how to reach that setting.
I am still fairly new to Arch. I know in windows I could right-click on the device from device manager and adjust device properties, but I am not sure how to find the device properties in Arch / KDE Plasma
I guess I could probably google my way through that though.

I gave you outputs to post and a link to a specific configuration example that would answer all of these.

Generally speaking this is an USB device and USB devices generally have a common standard they should be supporting which is the "driver" the kernel ultimately implements but focusrites have been notoriously difficult and constantly pop up for doing things most other devices have no issues with.

Sorry for the late response!

The solution was that I didn't have an issue in the 1st place. (or at least not with my interface)

What I found was that I don't have a delay when I record a mic line into it. Only my guitar was lagging.

The culprit ended up being my Impulse Response for my guitar. I didn't add it properly and that was creating issues.
