alsa-project/alsa-ucm-conf issue #398 was edited from Slabity:

Prior to version 1.2.10, my Scarlett Solo USB profiles looked like the following, where I could select profiles that explicitly enabled or disabled either the Inputs or Outputs:


As of 1.2.11, these profiles have disappeared and have left only a couple of profiles that do not provide the same functionality:


Other devices like my GPU's HDMI/DP Audio and motherboard's "Starship/Matisse HD Audio Controller" continue to expose the wider variety of profiles. It is only this device that seems to have the issue.

I originally reported this on #346 as I thought it was related, but was told it might be a different issue. What makes me worried is the mention that this is "expected" now despite it breaking my audio setup. I can no longer select the "Digital Stereo (IEC958) Input" to exclusively enable the Input Device *without* enabling the Output Device.

Here's some more information about the device:
