alsa-project/alsa-ucm-conf pull request #145 was opened from nodens: Arturia Minifuse 2 (https://www.arturia.com/products/audio/minifuse/minifuse2) is an USB audio interface with 2 mono inputs and 2 channel outputs. It uses 1 subinterface with 4 capture and 4 playback channels: Capture channels: - Mic/Line/Inst 1 (Mono) - Mic/Line/Inst 2 (Mono) - Loopback (Stereo, L+R) Playback: - Main (Stereo, L+R) - Loopback (L+R) The Loopback capture and playback are intended to ease recording sound from the computer, e.g if you're doing a podcast and want to record something that plays from the computer. Of course us linux user don't need that, since we have many tools able to do that. However, without a dedicated use case, alsa treats the channels as surround 4.0, which make the card difficult to use. At this stage, no controls are available. TODO/FIXMEs: - add a channel map override on the pcm device ?
