alsa-project/alsa-ucm-conf issue #104 was opened from craftyguy:

I'm using a ucm2 config that is not yet upstream (see [1]), and 1e6297b650114cb2e043be4c677118f971e31eb7 has caused devices to get renamed; they are now prefixed with `_ucm0001.`:

This breaks things [like pulseaudio config](https://source.puri.sm/Librem5/librem5-base/-/blob/pureos/byzantium/default/audio/pulse/librem5.pa) that expects specific device names. Was this renaming intentional?
