UCM for Behringer UMC204HD broken

[GitHub issues - opened]

alsa-project/alsa-ucm-conf issue #177 was opened from gregory112:

This is related: [https://github.com/alsa-project/alsa-ucm-conf/pull/128](https://github.com/alsa-project/alsa-ucm-conf/pull/128).
I came from this issue I filed in Pipewire: [https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/2471](https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/2471).

So previously a while back, Behringer UMC204HD was detected as a single stereo input channel. This sound card has two inputs. However, just recently, the channel was separated into two mono channels, which was perfect. However, with the most recent update (I don't know if it's pipewire, pipewire-alsa, alsa-card-profiles, or alsa-ucm), it reverted back into the stereo single input (left/right) mode. What can I do to bring back the previous correct settings (apart from the bugs I filed in Pipewire)? I did not modify any ALSA UCM files.
