That has prevented the crash. I can have tested it and the input now can
be selected and functions (using sound out via internal into UF0202).

The Behringer UF0202 works in both "line" and "phono" as it is internal
to the device. However it is displayed as two separate input and two
separate output devices. A "Digital Output (S/PDIF)" and "Analogue
Output" with "Analogue Input" and "iec958-stereo-input". Both input
devices work when selected, both proving the same audio. I cannot test
the output at the moment. The UF0202 has no SPDIF interface (documented)
however I have the suspicion that it is the same hardware as the
"U-CONTROL UCA222". Can this quirk be put in ALSA to prevent confusion
and can there be a standardisation on "iec958" and "S/PDIF"?

Please feel free to ask for any more testing.
