I usually start jack2 like this (works with the
other device):
jackd -P98 -dalsa -dhw:2 -p512 -n3 -o2 -r44100
Have you verified the device number? The device number can change between
reboots even, so definitely could change when reinstalling your OS.
Easiest to check using aplay -l to list all ALSA devices, perhaps hw:2 is
no longer your UMC interface.
I find it's safer to use device names rather than numbers (unless you have two
identical ones).
My MIDI keyboard identifies as 'Hua Xing'
and audio is 'HW:K6'

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
