Does anyone know what the root cause of this digital in/out appearing? Is it within ALSA or is there something wrong with the USB AudioControl interface descriptor being returned by the USB audio device? I ask because I have a custom USB audio device with this issue.

USB headsets and mics which are analog only show up with a digital profile as well. While this is probably not a 12.04 regression, with the revamp of the sound settings UI this becomes annoying, as seen in the attached screenshot.
