alsa-project/alsa-ucm-conf pull request #128 was opened from brndd: Adds a profile for the Behringer UMC204HD to split a 4-channel output into two outputs, and a 2-channel input into two inputs, as per the physical layout of the device. I have very little idea what I'm doing, so let me know if something looks incorrect (there's one thing that looks incorrect even to me which I shall point out in a comment below). The config does at least work, though.
