Hi there, first post of mine on these forums!
I have an Arturia Audiofuse Studio which was previously working via this patch I made to alsa-ucm-conf based on this git issue, but after running a full system update via sudo pacman -Syu, audio playback doesn't work. The device shows in Sound Settings (KDE Plasma) as "Audiofuse Studio Pro" with 18 channels, but I can't get audio to pass through the inputs or outputs.
What's more, the device monitor and output channels show up in QPWGraph. That said, I don't see any signals in software like Reaper, and I don't get playback on things like youtube videos, vlc audio file playback, etc.
I'm sure I messed something up in my alsa-ucm-conf patch that isn't playing well with the latest updates, but I'm in a bit over my head with it so I figured I'd ask for some help.
Here's the output of pactl list sources:

I'm a musician and this interface working as expected was the last blocker to me actually daily-driving Linux for my work, so I'm eager to get back to that.
Cheers!
