Scarlett 16i16 4th Gen: fcp-tools not finding the card #2

Description

@grinness

Hi,

I hope you can help me figure this out.
I have been following the instructions as in the git repo

I am on Arch linux liquorix kernel 6.14.1:

> uname -a     
Linux gemini 6.14.1-lqx1-1-lqx #1 ZEN SMP PREEMPT_DYNAMIC Mon, 07 Apr 2025 13:31:00 +0000 x86_64 GNU/Linux

I have built from git a package and installed:

>  pacman -Ql fcp-support-git
fcp-support-git /usr/
fcp-support-git /usr/local/
fcp-support-git /usr/local/bin/
fcp-support-git /usr/local/bin/fcp-server
fcp-support-git /usr/local/bin/fcp-tool
fcp-support-git /usr/local/lib/
fcp-support-git /usr/local/lib/systemd/
fcp-support-git /usr/local/lib/systemd/system/

fcp-support-git /usr/local/share/fcp-server/fcp-alsa-map-821c.json
fcp-support-git /usr/local/share/fcp-server/fcp-alsa-map-821d.json

when I turn on the card journalctl -f shows:
