I'm trying to make sound using orca and fluidsynth, but I simply can't get orca to recognize the MIDI instrument (it doesn't show up in the menu). The narrow question is: how can I get orca to play nice with pipewire? The more general question, and frankly the one I'm interested in, is how can I get orca to play sounds (i.e., what is the recommended setup?).

I'm on Alpine Linux (musl). I use pipewire.

Thanks.
