I usually start jack2 like this (works with the other

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.
