alsa-project/alsa-ucm-conf pull request #203 was opened from PatrickLang:
This cleans up the Focusrite Scarlett 2i4 Gen2 device a bit. This device is split into two stereo pairs for output, and has 2 mic/line/instrument inputs. There are no toggles or mixer controls exposed to Alsa.
It has hardware switches for: - Headphones - can monitor line outputs 1+2 or 3+4 - Headphone input/playback mix - Monitor out (Line 1+2) - Each input has a level pot, and switches for pad and Z (line/inst) - There is 1 physical +48v switch
Please let me know if any more info would be helpful. I have captured some more notes showing before/after state at https://gist.github.com/PatrickLang/79a3090eea6f2d640179457b5d428134#scarlet...
I'm planning to write a UCM2 profile for the more complicated Focusrite Scarlett 18i8 Gen2 next which has more inputs, but also multiple mix busses controllable through Alsa
