Arturia AudioFuse support
I own Arturia AudioFuse. I am on Linux Mint and I got faux "Analogue Surround 7.1 Output" probably since Linux Mint 20. The version before that was property split input multiple devices in the system sound settings. Not a big deal, but occasionally I want just plug it in to listen to music on a good DAC and headphone (without setting up Jack and ingestigating XRUNs). I didn't find a simple workaround and just used Jack (in my instrument/recording setup).
I recently updated to Linux Mint 22.1 (based on Ubuntu 24.04) and wanted to explore if there's a solution, since LM's audio is now based in PipeWire. Out of the box I got the same "Analogue Surround 7.1 Output". After a lot of searching, I found that some Arturia products are already in my /usr/share/alsa/ucm2/USB-Audio/Arturia (alsa-ucm-conf 1.2.10-1ubuntu5.4).
Then I just applied https://github.com/alsa-project/alsa-ucm-conf/commit/b68aa52, cp Minifuse-12.conf Audiofuse.conf, cp Minifuse-12-HiFi.conf Audiofuse-HiFi.conf, added an include in USB-Audio.conf and s/minifuse12/audiofuse in the files. systemctl --user restart pipewire pipewire-pulse wireplumber and viola -- I've got the split back! :-) I'm only interested in "Main Output L/R AudioFuse", which is working. The rest may not, and I still plan to use Jack for recording. But I'm happy to validate things on the interface.
Attaching my patch over Minifuse-12 for completeness.
